Devi Lal Kikraliya* (Scholar) Dr. U.N. Shukla** (Major advisor) ABSTRACT A field experiment entitled “Bio-efficacy of sorghum extract and herbicide on growth, yield and quality of wheat (Triticum aestivum L.)” was conducted at Instructional Farm, College of Agriculture, Jodhpur (Rajasthan) during rabi season of 2021-22. Field experiment was laid out in randomized block design (RBD) with eleven treatment combinations and replicated thrice. The treatments taken in the investigation were W1-sorghum extract (1:1), W2- Sorghum extract (1:2), W3- Sorghum extract (1:3), W4-Sorghum extract (1:4), W5-Ready mix of clodinafop + metsulfuron 64 g/ha, W6-Sorghum extract (1:1) + ready-mix of clodinafop + metsulfuron 64 g/ha, W7- Sorghum extract (1:2) + ready-mix of clodinafop + metsulfuron 64 g/ha, W8- Sorghum extract (1:3) + ready-mix of clodinafop + metsulfuron 64 g/ha, W9- Sorghum extract (1:4) + ready-mix of clodinafop + metsulfuron 64 g/ha, W10- Weed free and W11- Weedy check. According to treatments, different ratio of sorghum extract applied either alone or with ready-mix herbicide. Results indicated that post-emergence and sequential application of sorghum extract (1:3) + ready-mix of clodinafop + metsulfuron 64 g/ha (W8) significantly reduced weed density and dry weight of C. murale L., C. album L., Rumex dentatus L., Asphodelus tenuifolius L. and Cyperus rotundus L. results in obtaining higher weed control efficiency at all the growth stages of crop that improved weed index and also lesser nutrient removals (N, P, K) recorded at 60 DAS and at harvest. Owing to reduction in weed infestation which improved growth attributes viz. final plant population including tillers (442/m2 ) at harvest, plant height (51.69, 83.72 and 90.49 cm), number of tillers (464, 453 and 442/m2 ), dry matter accumulation (374.24, 781.46 and 964.44 g/m2 ) at 60, 90 and at harvest, respectively, while SPAD chlorophyll meter reading (51.23 and 50.09) was significantly recorded at 60 and 90 DAS, respectively due to application of sorghum extract (1:3) + ready mix of clodinafop + metsulfuron 64 g/ha (W8) as compared to their higher concentration of sorghum extracts applied either alone or with ready-mix herbicide including weedy check (W11) during field experimentation at all growth stages except 30 DAS, where none of the treatments showed significant effects. Similarly, significantly higher number of effective tillers (414/m2 ), length of spike (17.50 cm), number of grains/spike (43.33) and 1000-grain weight (44.45 g) were recorded under post-emergence and sequential application of sorghum extract (1:3) + ready-mix of clodinafop + metsulfuron 64 g/ha (W8) resulted in production of higher grain yield (4543 kg/ha.), straw yield (5103 kg/ha.) and biomass yield (9646 kg/ha.) and also showed their efficacy in recording higher protein yield (438 kg/ha) and contents of N, P and K in grains and straw as well as their uptakes by wheat. Improved in grain yield that resulted in higher monetary advantages in terms of gross return (`1,20,351/ha), net return (` 87,830/ha) and B: C ratio (3.70) by the application of sorghum extract (1:3) + ready-mix of clodinafop + metsulfuron 64 g/ha (W8) as compared to weedy check (W11). Among alone application of sorghum extracts, application of sorghum extracts (1:3) significantly reduces weeds and recorded higher growth, yield attributes, yield, nutrients uptakes and economics as well as higher microbial population as compared weedy check (W11).ThesisItem Open Access Effect of Agronomic Biofortification of Zinc and Iron on Growth and Yield of Chickpea (Cicer arietinum L.)

Shukla, Assistant Professor, Department of Agronomy, College of Agriculture, JodhpurApplication of ZnSO4 @ 25 kg/ha (SA) + 0.5% FeSO4 (FA) significantly increased growth attributes of chickpea viz. plant height (36.81, 68.54 and 70.64 cm), dry matter accumulation/plant (6.11, 15.72 and 26.04 g/plant), number of primary branches/plant (5.56, 6.53 and 6.41) and secondary branches/plant (17.36, 22.15 and 24.69) at 60, 90 DAS at harvest, respectively, while SPAD chlorophyll meter reading (44.94 and 44.89), number of nodules/plant (42.12 and 32.83), fresh weight of nodules (429.00 and 140.17 mg/plant) and dry weight of nodules (173.20 and 60.06 mg/plant) at 60 and 90 DAS, respectively and increased yield attributing characters viz. number of pods/plant (45.16), number of seed/pod (2.18) and 100-seed weight (15.98 g) resulted in higher seed (1,827 kg/ha), stover (3,449 kg/ha) and biological yield (4,876 kg/ha) along with harvest index (37.47 %) over rest of the treatments. Similarly, Application of ZnSO4 @ 25 kg/ha (SA) + 0.5% FeSO4 (FA) significantly improved contents of nitrogen (3.56 and 1.38%) in seed and stover, respectively with their uptakes, while significantly higher contents of zinc (37.46 and 22.95 mg/kg) in seed and stover with their uptakes (60.98 and 667.03 g/ha) in seed and stover, respectively resulted in total uptake of zinc (728.01 g/ha) under application of ZnSO4 @ 25 kg/ha (SA) + 0.5% ZnSO4 (FA). However, application of FeSO4 @ 25 kg/ha (SA) + 0.5% FeSO4 (FA) significantly improved contents of iron (69.17 and 390.83 mg/kg) in seed and stover with their uptakes (93.91 and 1,040.43 g/ha) in seed and stover, respectively resulted in total uptake of iron (1,134.34 g/ha) during investigation. Improvements in yield of chickpea, which subsequently improved gross return ( 1,04,327 and 94,122/ha), net return ( 77,648 and 67,491/ha) and B: C ratio (3.91 and 3.53) under the application of ZnSO4 @ 25 kg/ha (SA) + 0.5% FeSO4 (FA) followed by ZnSO4 @ 25 kg/ha (SA) + 0.5% ZnSO4 (FA), respectively during investigation.ThesisItem Open Access EFFECT OF DATE OF SOWING AND PLANT GEOMETRY ON GROWTH AND YIELD OF CHIA (Salvia hispanica L.)”(Agriculture University, Jodhpur, Jodhpur, 2018-05-25) Ms. Anjali Jingar; Dr. Moola Ram; Kumhar S.R, U.N. Shukla, B. R. ChoudharyThesisItem Open Access Effect of Jiwamrita on Growth and Yield of Organic Mungbean [Vigna radiata (L.) Wilczek](Agriculture University, Jodhpur, 2021-09-04) Swami, Anil; Ram, Moola; Mehriya, M. L.; Meena, R. C.A field experiment “Effect of Jiwamrita on Growth and Yield of Organic Mungbean [Vigna radiata (L.) Wilczek]” was conducted at Agricultural Research Station, Mandor during Kharif 2020 in loamy sand soil, low in nitrogen, medium in phosphorus and high in potassium content with pH 8.2. Treatments in main plots were mode of application, M1: Soil application, M2: Foliar application and M3: Soil and foliar application and in sub plots were doses of Jiwamrita: S1: Control, S2: 50 ml/l, S3: 100 ml/l and S4: 150 ml/l which were replicated thrice in split plot design. Results revealed that Jiwamrita as combined soil and foliar application (M3) significantly increased the plant height, number of pods/plant and number of grains/pod of organic mungbean over soil application alone (M1) whereas number of branches/plant and grain yield were recorded significantly higher under combined soil and foliar application (M3) as compared to soil application alone (M1) and foliar application alone (M2). The maximum growth and yield attributes were recorded with the dose of Jiwamrita @ 150 ml/l of solution (S4) which was found statistically at par with the dose of Jiwamrita @ 100 ml/1 of solution (S3). However, the maximum benefit cost ratio (3.2) was recorded with the dose of Jiwamrita @ 100 ml/1 of solution (S3). From the study, it was concluded that Jiwamrita was found effective in organic mungbean under combined soil and foliar mode of application and a dose of Jiwamrita @ 100 ml/l of solution was found beneficial in terms of increasing growth attributes, yield attributes and economic return of organic munbean. These results are based on one year experiment hence requires validation through further experiments to formulate recommendation.ThesisItem Open Access Effect of Levels of Sulphur and Antioxidants on Sustainable Cumin (Cuminum cyminum L.)

Field experiment was laid out in factorial randomized block design (FRBD) with sixteen treatment combinations and replicated thrice. The treatments were taken in the investigation viz. control (N0), Seed Treatment with 5ml/kg nano DAP (N1), Seed treatment with 5ml/kg nano DAP + one foliar spray of nano urea (2 ml/l of water) at 25 DAS (N2), Seed treatment with 5ml/kg nano DAP + Two foliar spray of nano urea (2 ml/l of water) at 25 and 35 DAS (N3) under nano fertilizers, however, control (F0), 100% RDN (F1), 75% RDN (F2), 50% RDN (F3), under RDN levels. Results revealed that application of Seed treatment with 5ml/kg nano DAP + Two foliar spray of nano urea (2 ml/l of water) at 25 and 35 DAS (N3) of sesame significantly had higher growth attributes viz. plant height (32.3, 69.1 and 99.6 cm), dry matter accumulation (1.78, 6.84 and 11.86 g/plant), chlorophyll content in leaves (SPAD value) (36.0, 50.3 and 70.3 SPAD-Value), number of branches (1.65 and 2.77), number of leaves (18.5, 49.8 and 81.3/plant) at 30, 45 and 60 DAS, respectively, as well as significantly increases yield attributing characters viz. length of capsule (2.6 cm), width of capsule (0.82 cm), number of capsules/plant (33.0/plant), weight of capsule (18.68 g/plant), number of seed/capsule (48.5/capsule), seed yield (888 kg/ha), straw yield (2079 kg/ha) and biological yield (2911 kg/ha) along with harvest index (30.42%) followed by the treatment with Seed treatment with 5ml/kg nano DAP + one foliar spray of nano urea (2 ml/l of water) at 25 DAS (N2). Similar trends were also observed with nitrogen and phosphorus content in seed (3.53 and 0.553%) and straw (1.77 and 0.283%) results in higher uptake of nitrogen and phosphorus by seed (33.42 and 4.62 kg/ha) and straw (32.91 and 5.76 kg/ha), respectively as well as protein content (22.03%) of sesame and showed significant superiority over rest of the treatments. Increase in seed and straw yield, which subsequently improved gross returns ( 67756 and 61413/ha), net returns ( 41857 and 36207/ha) and B C ratio (2.59 and 2.31) due to application of seed treatment with 5ml/kg nano DAP + Two foliar spray of nano urea (2 ml/l of water) at 25 and 35 DAS (N3) and seed treatment with 5ml/kg nano DAP + one foliar spray of nano urea (2 ml/l of water) at 25 DAS (N2), respectively. Results further revealed that among different levels of RDN, 100% RDN (F1) was remained at par with 75% RDN (F2) with respect to all parameters taken during experiment. Application of 100% RDN (F1) significantly increases growth attributes of sesame viz. plant height (33.3, 69.9 and 100.3), dry matter accumulation (1.85, 6.71 and 11.31 g/plant), chlorophyll content in leaves (SPAD value) (36.3, 49.6 and 69.8 SPAD value), number of branches (1.61 and 2.63/plant), number of leaves (18.2, 50.7 and 82.5/plant) at 30, 45 and 60 DAS, respectively, that enhanced yield attributing characters viz. length of capsule (2.6 cm), width of capsule (0.84 cm), number of capsules/plant (32.2/plant), weight of capsule (20.08 g/plant), number of seed/capsule (49.2/capsule), seed yield (922 kg/ha), straw yield (2161 kg/ha) and biological yield (3026 kg/ha) along with harvest index (30.59%) over its lower dose i.e. 75% RDN (F2), 50% RDN (F3) and control (F0). It was also recorded significantly higher nitrogen and phosphorus content in seed (3.08 and 0.552%) and straw (1.36 and 0.233%) results in higher uptake of nitrogen and phosphorus by seed (33.38 and 4.39 kg/ha) and straw (36.28 and 5.52 kg/ha), respectively as well as protein content (22.42%) of sesame over rest of the treatments, but remained at par with 75% RDN (F2). Improvement in yield of sesame, which subsequently improved gross returns ( 71566 and 59541/ha), net returns ( 46002 and 34116/ha) and B C ratio (2.80 and 2.26) under the treatment 100% RDN followed by 75% RDN, respectively. Based on net return and B C ratio, application of 75% RDN (F2) with seed treatment with 5ml/kg nano DAP + Two foliar spray of nano urea (2 ml/l of water) at 25 and 35 DAS (N3) was more remunerative treatments in sesame as compared to rest of the treatments.ThesisItem Open Access Effect of Nano Fertilizers on Productivity of Wheat (Triticum aestivum L.)(Agriculture University, Jodhpur, 2024-03-16) Borana, Hitesh; Singh, IshwarA field experiment was carried out to study the “Effect of nano fertilizers on productivity of wheat (Triticum aestivum L.)” at Instructional Farm, College of Agriculture, Jodhpur (Agriculture University, Jodhpur, Rajasthan) during Rabi seasons of 2021-22 and 2022-23. The field experiment was laid out in randomized block design (RBD) with fourteen treatments replicated thrice. The treatments comprised of T1-100% RDF + two foliar spray of nano N at 35 & 55 DAS, T2-100% RDF + foliar spray of nano P at 35 DAS, T3-100% RDF + ST with nano P at 5 ml/kg seed and two foliar spray of nano N at 35 & 55 DAS, T4-75% RDF + two foliar spray of nano N at 35 & 55 DAS, T5-75% RDF + foliar spray of nano P at 35 DAS, T6- 100% RDF + ST with nano P at 5 ml/kg seed and two foliar spray of nano N at 35 & 55 DAS, T7-50% RDF + two foliar spray of nano N at 35 & 55 DAS, T8-50% RDF + foliar spray of nano P at 35 DAS, T9-50% RDF + ST with nano P at 5 ml/kg seed and two foliar spray of nano N at 35 & 55 DAS, T10-Foliar spray of nano P at 35 DAS + two foliar spray of nano N at 35 & 55 DAS, T11-ST with nano P at 5 ml/kg seed + foliar spray of nano P at 35 DAS + two foliar spray of nano N at 35 & 55 DAS, T12- ST with nano P at 5 ml/kg seed + two foliar spray of nano N at 35 & 55 DAS, T13- 100% RDF through conventional fertilizers and T14-Control. Findings based on pooled analysis indicate that the highest plant height (93.5 cm) and dry matter accumulation (1004.7 g/m2 ) at harvest stage were recorded with the application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS which was statistically at par with 100% RDF + two foliar spray of nano N at 35 & 55 DAS. Similarly, the highest values of CGR between 40-80 DAS (16.40 g/m2/day) and 80 DAS-at harvest (3.86 g/m2/day) were also recorded with application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS, on pooled basis. Application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS substantially improved yield attributing characters viz., number of tillers/m2 (431), no. of spikes/m2 (414), spike length (17.03 cm), no. of grains/spike (45.24) and test weight (46.32 g) over control. Application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS recorded significantly higher grain yield (4,399 kg/ha), straw yield (5,525 kg/ha) and biological yield (9,923 kg/ha) and crude protein content (10.45%) over control on pooled basis. Considerably higher N (25.97 & 83.10 kg/ha) and P (4.39 & 19.81 kg/ha) uptake by wheat plant at 40 & 80 DAS were recorded under application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS over control, respectively. However, it remained at par with 100% RDF + two foliar spray of nano N at 35 & 55 DAS. Significantly higher nitrogen and phosphorus uptake by grain (80.63 & 15.39 kg/ha) and straw (27.99 & 10.47 kg/ha) were recorded by 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS over control, on pooled basis. Post-harvest soil fertility analysis of wheat crop revealed that application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS significantly enhanced available nitrogen (182.49 kg/ha), phosphorus (24.14 kg/ha) and potassium (323.23 kg/ha) recorded in soil after harvest of wheat over 50% of RDF in combination with nano fertilizers and control, on pooled basis. The microbial population of bacteria (55.55 × 107 CFU/g of soil) and fungi (29.07 × 104 CFU/g of soil) recorded at post-harvest stage were the highest with application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS which was on par with 100% RDF + two foliar spray of nano N at 35 & 55 DAS. Economic analysis predict, that application of 100% RDF + ST with nano P and two foliar spray of nano N at 35 & 55 DAS gave maximum grain yield (4,399 kg/ha), net return (₹ 79,814/ha) and B: C ratio (2.94). Thus, based on the data of two years, it can be concluded that wheat grown under the agro-climatic condition of Zone-Ia, can be fertilized with 100% RDF (90 kg N/ha, 40 kg P2O5 and 20 kg K2O/ha) along with seed treatment with nano P @ 5 ml/kg of seed and two foliar spray of nano N @ 4 ml/L of water at 35 & 55 DAS for higher production and net return from wheat.ThesisItem Open Access Effect of phosphorus and biofertilizers on growth and yield of mungbean [Vigna radiata (L.)

The field experiment was comprised of four levels of drip irrigation (1.0, 0.8, 0.6 and 0.4 PEF) in main plots, two planting methods (Direct sowing and Transplanting) in sub plots and three mulches (No mulch, Straw mulch and Plastic mulch) in sub-sub plots. The trial was laid out in split plot design with three replications and 24 treatment combinations. The results revealed that progressive increase in levels of drip irrigation from 0.4 to 1.0 PEF significantly improved growth parameters, yield attributes and yield, N, P and K absorption by the crop. Plant height, dry matter accumulation, total chlorophyll content and relative water content at 70, 105 DAS and at harvest, number of branches/plant at 70 DAS and at harvest were significantly higher with drip irrigation at 1.0 PEF on pooled basis. However, significantly higher root growth parameters viz. root length, root volume and root dry matter were recorded with drip irrigation at 0.6 PEF in both the seasons as well as on pooled basis. Drip irrigation applied at 1.0 PEF produced seed yield of 2482 kg/ha, which was significantly higher by 13.23, 32.09 and 79.85 percent over 0.8 (2192 kg/ha), 0.6 (1879 kg/ha) and 0.4 PEF (1380 kg/ha), respectively. The volatile oil yield (34.84 kg/ha) and protein yield (252.23 kg/ha) were significantly higher at this level of drip irrigation compared to its lower levels. The gross monetary returns (2,62,013 ₹/ha), net monetary returns (1,96,058 ₹/ha) and benefit cost ratio (3.99) were also highest under this treatment. The maximum consumptive use of water (590.1 mm) was computed with highest drip irrigation volume (1.0 PEF), whereas water use efficiency (5.24 kg/m3 ) and water productivity (557.32 ₹/m3 ) was maximum with lowest level of drip irrigation (0.4 PEF). Further, transplanting method consistently outperformed direct sowing resulting to enhanced growth parameters viz. plant height, dry matter accumulation, total chlorophyll content, root volume and root dry matter at 35, 70, 105 DAS and number of branches/plant at 70 DAS and at harvest and yield attributes viz. number of umbels/plant (16.0), number of umbellets/umbel (14.1), number of seeds/umbellet (18.3), number of seeds/plant (4177), test weight (7.20 g), seed yield/plant (26.15 g/plant) and seed yield (2141 kg/ha), stalk yield (4954 kg/ha) and biological yield (7095 kg/ha) on pooled basis. Additionally, N, P and K absorption as well as their uptakes by crops, volatile oil content (1.60 percent) and its yield (33.62 kg/ha), protein content (9.34 percent) and respective yield (204.58 kg/ha) were also significantly higher with transplanting method compared to direct sowing. In terms of economic returns, transplanting gave maximum gross monetary returns (2,25,778 ₹/ha), net monetary returns (1,58,294 ₹/ha) and benefit cost ratio (3.35). Moreover, consumptive use of water was not significantly varied due to planting methods. However, maximum water use efficiency (5.00 kg/m3 ) and water productivity (529.89 ₹/ha) were highest under transplanting method. Among mulches, straw and plastic mulches recorded significantly higher growth and yield attributes over no mulch in both the seasons. However, the use of straw mulch recorded significantly improved growth attributes, yield attributes and yield, NPK content and their uptake by fennel, volatile oil yield and protein yield compared to plastic mulch and no mulch in both the seasons of experimentation. The significantly higher seed yield (2233 kg/ha), stalk yield (5216 kg/ha), biological yield (7449 kg/ha), volatile oil content (1.59 percent) and yield (34.98 kg/ha), protein content (9.35 percent) and protein yield (213.01 kg/ha) were recorded with the application of straw mulch. The maximum consumptive use of water was computed under no mulch (451.5 mm). Whereas, maximum water use efficiency (5.16 kg/m3 ) and water productivity (542.70 ₹/m3 ) were calculated with the use of straw mulch. Further, the highest gross monetary returns (2,35,790 ₹/ha), net monetary returns (2,07,060 ₹/ha) and benefit cost ratio (3.65) were recorded with straw mulch. The interaction effect between levels of drip irrigation and planting methods, levels of drip irrigation and mulches, planting methods and mulches were found significant in both the seasons as well as on pooled basis. Drip irrigation at 1.0 PEF superimposed with transplanting recorded significantly higher plant height and dry matter accumulation at 105 DAS and harvest, yield attributes viz. number of umbels/plant (19.7), number of umbellets/umbel (17.0), number of seeds/umbellet (20.8), number of seeds/plant (5429), seed yield/plant (31.20 g/plant) and seed yield (2685 kg/ha), stalk yield (5776 kg/ha), biological yield (8461 kg/ha), volatile oil yield (38.29 kg/ha), protein yield (278.31 kg/ha) over rest of the combination. NPK uptakes by seed (44.59, 14.24 and 8.92 kg/ha) and stalk (47.02, 12.12 and 86.45 kg/ha) of fennel, respectively were also significantly enhanced with this combination. Among the interaction between the combination of levels of drip irrigation and mulches, drip irrigation at 1.0 PEF and straw mulch recorded significantly higher yield attributes viz. number of umbels/plant (19.0), number of umbellets/umbel (16.8), number of seeds/umbellet (19.7), number of seeds/plant (5133), seed yield/plant (33.22 g/plant) and seed yield (2796 kg/ha), stalk yield (6123 kg/ha) and biological yield (8919 kg/ha). This combination also enhanced volatile oil yield (40.18 kg/ha) and protein yield (290.41 kg/ha) as well as NPK uptake by seed (46.47, 15.06 and 9.29 kg/ha) and stalk (50.42, 13.09 and 91.79 kg/ha) of fennel, respectively. Likewise, when transplanting combined with straw mulch, it also significantly improved seed yield (2348 kg/ha), stalk yield (5338 kg/ha), biological yield (7687kg/ha). Moreover, volatile oil yield (37.34 kg/ha), protein yield (228.11 kg/ha) and uptake of NPK by crop were also significantly higher with this combination over rest of the treatment combinations.ThesisItem Open Access Effect of Seed Priming and Foliar Spray of Stress Mitigating Chemicals on Growth and Yield of Mungbean [Vigna radiata (L).

Variety ‘MH-421’ (V2) recorded higher nitrogen contents in seed and stover (3.74 and 1.22%), phosphorus content in grain and stover (0.431 and 0.235%) and potassium content in grain and stover (0.97 and 1.64%) as compared to ‘GM-7’ (V1). Similar trends was apparent with respect to NPK uptake by grain and stover. Increase in grain and stover yield, which subsequently improved gross return ( 93,629/ha), net return ( 70,120/ha) and benefit: cost ratio (3.98) under variety ‘MH-421’ (V2) as compared to ‘GM-7’ (V1). Results further revealed that among treatments of stress mitigating chemicals, application of seed priming with thiourea @ 500 ppm + foliar spray @ 500 ppm at flower initiation stage (C3) of mungbean significantly higher dry matter accumulation/plant (16.56 and 27.62 g), number of trifoliate leaves/plant (15.55 and 10.52) and chlorophyll content (2.39 and 1.29 mg), root length (14.8 and 16.6 cm), root volume (7.02 and 11.90 ml) and number of major rootlets/plant (15.59 and 17.76) at 50 and at harvest stage as well as number of nodules/plant (33.79) and dry weight of nodules/plant (105.52 mg) at 50 DAS. Significant improvement was recorded in yield attributing characters viz. pod length (11.2 cm), number of pods/plant (31.3), numbers of grains/pod (11.3) and 1000-grains weight (40.84 g) resulted in higher grain yield (1136 kg/ha), stover yield (2456 kg/ha) and biological yield (3592 kg/ha) as well as harvest index (31.62 %) over other treatment. However, seed priming with thiourea @ 500 ppm + foliar spray @ 500 ppm at flower initiation stage (C3) and seed priming with salicylic acid @ 75 ppm + foliar spray @ 75 ppm + 2% urea at flower initiation stage (C5) were statistically at par with each others with respect to yield attributes and yield of mungbean. Higher nitrogen contents in grain (3.90%) and stover (1.30%), phosphorus content in grain (0.452%) and stover (0.247%) and potassium content in grain (1.02%) and stover (1.76%) as well as their uptakes in grain (44.30, 5.13 and 11.59 kg/ha) and stover (24.58, 6.06 and 43.22 kg/ha) of mungbean, respectively as well as protein content in grain (24.37%) and protein yield (276.84 kg/ha) of mungbean and showed significant superiority over rest of the treatments. Increase in grain and stover yield, which subsequently improved gross returns ( 1,02,809/ha), net return ( 78,487/ha) and B C ratio (4.22) due to application of seed priming with thiourea @ 500 ppm + foliar spray @ 500 ppm at flower initiation stage (C3). On the basis of net return and B C ratio, application of seed priming with thiourea @ 500 ppm + foliar spray @ 500 ppm at flower initiation stage (C3) under the variety ‘MH-421’(V2) was found more remunerative treatment in mungbean compared to rest of the treatments.ThesisItem Open Access Effect of Stress Mitigating Chemicals and Sulphur on Growth and Yield of Mungbean [Vigna radiata (L.) Wilczek](Agriculture University, Jodhpur, 2020) Bijarnia, Koushal Kishor; Shukla, U.

Taub](Agriculture University, Jodhpur, 2019-07-26) BORANA, HITESH; Singh, Ishwar; Ram, Moola; Shukla, U.N.A field experiment was conducted at Agricultural Research Station, Mandor, Agriculture University, Jodhpur during kharif season of 2018 to study the “Effect of Weed Management Practices on Growth and Yield of Clusterbean [Cyamopsis tetragonoloba (L.) Taub]”. The Field experiment was laid out in randomized block design (RBD) with ten treatments of replicated thrice. The treatments comprises of W1-Weedy Check, W2-Weed free, W3-Pendimethalin 750 g ha-1 (PE), W4- Imazethapyr 40 g ha-1 (Early post-emergence), W5-Pendimethalin + imazethapyr 750 g ha-1 (PE), W6-Imazethapyr + imazamox 50 g ha-1 (Early post-emergence), W7- Pendimethalin 750 g ha-1 (PE) + one hand weeding at 25 DAS, W8-Imazethapyr 40 g ha-1 (Early post-emergence) + one hand weeding at 35 DAS, W9-Pendimethalin + imazethapyr 750 g ha-1 (PE) + one hand weeding at 25 DAS, W10-Imazethapyr + imazamox 50 g ha-1 (Early post-emergence) + one hand weeding at 35 DAS. According to treatments, pendimethalin and its ready mix with imazethapyr was applied as pre-mergence (within 2 DAS), while imazethapyr and its ready mix with imazamox was applied as early post-emergence (20 DAS). Among treatments, application of imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS significantly reduced weed density of narrow and broad-leaved weeds and weed dry matter at 40, 60, 80 DAS and at harvest however, it was found at par with imazethapyr 40 g ha-1 (early post emergence) + one hand weeding at 35 DAS. Similarly, higher weed control efficiency was also obtained under these treatments which resulted in reduction of weed index as well.The plant height, no. of branches plant-1, dry matter accumulation (g plant-1) as well as yield attributing characters viz., no. of pods plant-1, no. of seeds pod-1 and 1000-seed weight of clusterbean were produced significantly higher under application of imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS. Due to better growth, higher number of yield attributes and less weed index, this treatment resulted in maximum seed yield of 1180 kg ha-1 which was statistically at par with weed free season long plot (1237 kg ha-1). Application of imazethapyr 40 g ha-1 (early post-emergence) + one hand weeding at 35 DAS produced seed yield of 1120 kg ha-1 which was statistically at par with imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS (1180 kg ha-1). The highest amount of total nitrogen uptake by crop (112.1 kg ha-1) was recorded with weed free treatment which remained at par with imazethapyr + imazamox 50 g ha-1 + one hand weeding at 35 DAS (106.5 kg ha-1). The lowest amount of nitrogen removal by weeds (22 kg ha-1) was obtained with the application of imazethapyr + imazamox 50 g ha-1 + one hand weeding at 35 DAS followed by imazethapyr 40 g ha-1 + one hand weeding at 35 DAS. The highest net monetary return and B:C ratio of 49,693 and 3.23 were obtained with imazethapyr + imazamox 50 g ha-1 (early post-emergence) + one hand weeding at 35 DAS, respectively followed by imazethapyr 40 g ha-1 (early post emergence) + one hand weeding at 35 DAS.ThesisItem Open Access Effect of Zinc and Iron Application on Growth and Yield of Mungbean [Vigna radiata (L.) Wilczek](Agriculture University, Jodhpur, 2019-06-19) Gehlot, Navratan; Ram, Moola; Choudhary, B.R.; Raiger, P.R.Field experiment was conducted at Agricultural Research Station, Mandor, Agriculture University, Jodhpur during kharif season of 2018 on sandy loam soil of low nitrogen, phosphorus, zinc and iron and medium potassium content with 7.8 pH of soil. The experiment was laid out in randomized block design (RBD) with 3 replications. The treatments comprised of T1- RDF (common to all treatments), T2- Soil application of zinc sulphate at 25 kg/ha, T3- Foliar application of zinc sulphate at 0.5% at 35 DAS, T4 = (T2+T3), T5- Soil application of ferrous sulphate at 25 kg/ha, T6- Foliar application of ferrous sulphate at 0.5% at 35 DAS, T7 = (T5+T6), T8- Soil application of zinc sulphate and ferrous sulphate each at 25 kg/ha, T9 = (T8+T3), T10 = (T8+T6). The results in terms of plant height, dry matter accumulation, number of branches/plant, number of pods/plant, number of seed/pod, test weight, seed and stover yield of mungbean increased significantly due to soil application of zinc sulphate and ferrous sulphate each at 25 kg/ha (T8) over control. The maximum increment in the growth and yield attributes were due to application of T10 followed by T9 but these were statistically at par with T8. The significantly higher seed yield (1323 kg/ha) and higher net returns ( 83,128/ha) was recorded with application of T8 which was further increased due to T9 and T10 but BC ratio remained highest (4.52) with T8. Therefore, it was concluded that soil application of zinc sulphate and ferrous sulphate each at 25 kg/ha can be used for higher grain yield, net return and BC ratio of mungbean in western Rajasthan conditions. These results are based on one year experiment hence requires validation through further experiments to formulate recommendation.ThesisItem Open Access Efficacy of Herbicides in Fenugreek (Trigonella foenum-graecum L.)(Agriculture University, Jodhpur, 2022-11-26) Meena, Vikash; Mehriya, M.L.The field experiment entitled “Efficacy of Herbicides in Fenugreek (Trigonella foenum-graecum L.)” was conducted at experimental field of the Agricultural Research Station Mandor, Jodhpur during Rabi season of 2021-22.

Similarly, higher weed control efficiency was also obtained under these treatments which resulted in reduction of weed index as well. The plant height and crop dry matter accumulation as well as yield attributing characters viz., number of pods/plant, pod yield/plant, number of kernels/pod and seed index of groundnut were enhanced significantly under application of pendimethalin + imazethapyr at 1.0 kg/ha (PE) + one manual weeding and pendimethalin at 1.0 kg/ha (PE) + imazethapyr at 75 g/ha at 20 DAS. Due to better growth and yield attributes and less weed index, these treatments resulted in higher pod, haulm, kernel and biological yields which were found statistically at par with weed free condition. Pre emergent application of pendimethalin + imazethapyr at 1.0 kg/ha + one manual weeding at 30 DAS and pendimethalin at 1.0 kg/ha (PE) + imazethapyr at 75 g/ha 20 DAS caused to increase the total nitrogen uptake by crop, protein content in kernel and oil out-turn compared to other treatments, but was found at par with weed free plot. These treatments also led to the lowest amount of nitrogen removal by weeds. The highest net returns (` 1,47,438/ha) and B: C ratio (3.44) were obtained under pendimethalin at 1.0 kg/ha (PE) + imazethapyr at 75 g/ha 20 DAS followed by pendimethalin + imazethapyr at 1.0 kg/ha (PE) + one manual weeding at 30 DAS (net returns ` 1,47,285/ha and B: C ratio 3.36 ).ThesisItem Open Access Efficacy of Herbicides on Growth and Yield of Chia (Salvia hispanica L.)(Agriculture University, Jodhpur, 2022) Kumar, Anuj; Ram, MoolaThe field experiment entitled “Efficacy of herbicides on growth and yield of chia (Salvia hispanica L.)” was conducted at Research Farm of ARS, Mandor, Jodhpur, Agriculture University, Jodhpur during Rabi season of 2021-22. The treatments consisting of ten treatments of weed management viz. bentazon 48% SL 500 g/ha at 30 DAS (T1), bentazon 48% SL 750 g/ha at 30 DAS (T2), fluazifop–p butyl 11.1% SL 100 g/ha at 30 DAS (T3), fluazifop–p-butyl 11.1% SL 200 g/ha at 30 DAS (T4), sulfentrazon 39.6% SC 50 g/ha as pre-emergence (T5), sulfentrazon 39.6% SC 75 g/ha as pre-emergence (T6), pendimethalin 38.7% CS 200 g/ha pre-emergence (T7), pendimethalin 38.7% CS 400 g/ha pre-emergence (T8), weed free (T9) and weedy check (T10) were laid out in randomized block design with three replications. Results revealed that post-emergence application of bentazon 48% SL 750 g/ha recorded significantly lower density of total weeds, total dry weight of weeds, weed index and higher weed control efficiency, growth attributes, yield attributes, yield, net returns and BC ratio as compared to weedy check. Among pre-emergence applied herbicides, sulfentrazon 39.6% SC 75 g/ha (T6) and pendimethalin 38.7% CS 400 g/ha (T8) were statistically at par and recorded significantly higher growth and yield attributes and lower total dry weight of weeds, weed index and higher weed control efficiency. Therefore, bentazon 48% SL 750 g/ha as post-emergence (30 DAS) herbicide and sulfentrazon 39.6% SC 75 g/ha or pendimethalin 38.7% CS 400 g/ha as pre-emergence can be used for weed control in chia crop.ThesisItem Open Access Efficacy of Herbicides on Growth and Yield of Isabgol (Plantago ovata Forsk.)(Agriculture University, Jodhpur, 2021-07-08) Kumar, Virender; Mehriya, M.L.; Shukla, U.N.; Raiger, P.R.A field experiment was conducted at Agricultural Research station, Mandor, Agriculture University, Jodhpur during rabi, 2019-2020 to study the “Efficacy of Herbicides on Growth and Yield of Isabgol (Plantago ovata Forsk.)”. The Field experiment was laid out in randomized block design (RBD) with ten treatments of replicated thrice. The treatment comprises of T1- Weedy check, T2- Weed free, T3- oxadiargyl at 40 g/ha (PoE), T4- oxadiargyl at 50 g/ha (PoE), T5- oxadiargyl at 70 g/ha (PoE), T6- oxyfluorfen at 40 g/ha (PoE), T7- oxyfluorfen at 50 g/ha (PoE), T8- oxyfluorfen at 70 g/ha (PoE), T9- sulfosulfuron at 20 g/ha (PoE) and T10- sulfosulfuron at 25 g/ha (PoE). Among treatments, application of postemergence herbicides i.e. oxadiargyl at 70 g/ha and oxyfluorfen at 70 g/ha significantly reduced weed density and total weed dry matter at 30, 60, 90 DAS and at harvest which was at par on 50 g/ha doses of these herbicides. Similarly, higher weed control efficiency was also obtained under these treatments which resulted in reduction of weed index as well. The plant height and crop dry matter accumulation as well as yield attributing characters viz., spikes/plant, length of spikes, and seeds/spikes of isabgol were enhanced significantly under PoE application of oxadiargyl and oxyfluorfen each at 50 g/ha over their lower dose (40 g/ha) and both doses of sulfosulfuron but found on par to oxyfluorfen and oxadiargyl each at 70 g/ha. Due to better growth and yield attributes and less weed index, these treatments resulted in higher seed, husk, straw and biological yields which were found statistically at par with weed free condition. PoE application of oxadiargyl and oxyfluorfen each at 50 g/ha caused to increase the total nitrogen uptake by crop compared to other treatments, but found at par with their higher dose (70 g/ha) and weed free environment. These treatments also led to the lowest amount of nitrogen removal by weeds. Oxadiargyl and oxyfluorfen each at 50 g/ha at 20 DAScomputed comparatively higher net returns 62663 and 62026 ₹/ha, and B: C ratio 3.05 and 3.10.
