ThesisItem Open Access Herbicidal weed management in chickpea (Cicer arietinum L.)(Agriculture University, Jodhpur, 2022-07-25) Yadav, Manisha; Singh, IshwarA field experiment entitled “Herbicidal weed management in chickpea (Cicer arietinum L.)” was conducted at Instructional Farm, Mandor, Jodhpur during Rabi season of 2021-22. Field experiment was laid out in randomized block design (RBD) with Ten treatments and replicated thrice. The treatments taken in the investigation were T1- Imazethapyr @ 50 g/ha at 20 DAS, T2- Propaquizafop+imazethapyr @ 50 g/ha at 20 DAS, T3- Sodium Acifluorfen+clodinafop propargyl @ 200 g/ha at 20 DAS, T4- Fomesafen+fluazifop-p-butyl @ 200 g/ha at 20 DAS, T5- Bentazon @ 750 g/ha at 30 DAS, T6- Pendimethalin+imazethapyr @ 750 g/ha as PE, T7 – Pendimethalin @ 750 g/ha as PE, T8- Sulfentrazone @ 75 g/ha as PE, T9- Weed Free and T10- Weedy Check. Among treatments, application of pendimethalin+imazethapyr @ 750 g/ha as PE significantly reduced weed density of Chenopodium murale L., Chenopodium album L. and Rumex dentatus L. as well as total density and dry weight of weeds at 30, 60, 90 DAS and at harvest. Similarly, higher weed control efficiency and Weed index was also obtained under these treatments. Weed free recorded significantly higher growth and yield attributing characters and yields over rest of the treatments. Among herbicidal treatments, plant height, no. of branches/plant, dry matter accumulation (g/m2) as well as yield attributing characters viz., no. of pods/plant, no. of seeds/pod, 100-seed weight and seed yield/plant of chickpea were produced significantly higher under application of pendimethalin+imazethapyr @ 750 g/ha as PE resulted in higher seed and stover yield. Despite higher yield and net returns, returns per rupee of investment (B:C ratio) were low with weed free treatment due to higher labour wages. Increase in seed and stalk yield, which subsequently improved gross returns, net returns and B: C ratio also and recorded highest under pendimethalin+imazethapyr @ 750 g/ha as PE.ThesisItem Open Access Effect of nano fertilizers on growth, yield and quality of sesame (Sesamum indicum L.)(Agriculture University, Jodhpur, 2023-10-03) Meena, Lal Chand; Ramawat, NaleeniA field experiment entitled “Effect of nano fertilizers on growth, yield and quality of Sesame (Sesamum indicum L.)” was conducted at Instructional Farm, College of Agriculture, Jodhpur (Rajasthan) during kharif season 2022.

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 Efficacy of Post-emergence Herbicides on Growth and Yield of Mungbean [Vigna radiata (L).

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 Effect of Planting Methods, Mulches and Drip Irrigation Scheduling on Fennel (Foeniculum vulgare Mill.)(Agriculture University, Jodhpur, 2024-01-30) Kumar, Sunil; Mehriya, M. L.; Mehriya, M. L.A field investigation was undertaken to study the effect of planting methods, mulches and drip irrigation scheduling on fennel (Foeniculum vulgare Mill.) at Instructional Farm of College of Agriculture, Agriculture University, Jodhpur during the Rabi seasons of 2020-21 and 2021-22. 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 Bio-efficacy of Sorghum Extract and Herbicide on Growth, Yield and Quality of Wheat (Triticum aestivum L.)(Agriculture University, Jodhpur, 2022-07-20) KIKRALIYA, DEVI LAL; Shukla, U.N.; Mehriya, M.L.; Raiger, P.R.Bio-efficacy of Sorghum Extract and Herbicide on Growth, Yield and Quality of Wheat (Triticum aestivum L.) 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).
