ThesisItem Open Access Effect of phosphorus and biofertilizers on growth and yield of mungbean [Vigna radiata (L.) Wilczek](Agriculture University, Jodhpur, 2019-06-19) Mandiwal, Mukesh; Shukla, U. N.; Mehriya, M. L.; Raiger, P. R.A field experiment entitled “Effect of phosphorus and biofertilizers on growth and yield of mungbean [Vigna radiata (L.) Wilczek]” was conducted at Agricultural Research Station, Mandor, Jodhpur during kharif season of 2018. A field experiment was laid out in randomized block design (RBD) with nine treatments and replicated thrice. The treatments taken in the investigation were Control (F0), 20 kg P2O5 ha-1 (F1), 40 kg P2O5 ha-1 (F2), 20 kg P2O5 ha-1 + PSB (F3), 40 kg P2O5 ha-1 + PSB (F4), 20 kg P2O5 ha-1 + Aspergillus awamori (F5), 40 kg P2O5 ha-1 + Aspergillus awamori (F6), 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8). According to treatments, seeds of mungbean were inoculated with PSB + Aspergillus awamori, while different doses of phosphorus were applied in the soil. Among growth attributes viz. plant height (14.73, 46.08 and 49.48 cm), dry matter accumulation plant-1 (3.02, 21.45 and 24.63 g) at 30, 60 DAS and at harvest, respectively, while final plant population (3.29 lakh ha-1), number of branches plant-1 (7.81) as well as yield attributing characters viz. number of pods plant-1 (48.34), seeds pod-1 (12.57) and 1000-seeds weight (44.66 g) resulted in higher seed yield (1583 kg ha-1) and stover yield (3504 kg ha-1) were recorded significantly under treatment applied with 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) followed by 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7). However, 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg P2O5 ha-1 + Aspergillus awamori (F6) were statistically at par with each others with respect to growth attributes, yield attributes and yield of mungbean.Similarly, integrated application of 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) recorded significantly higher phosphorus content in seeds (0.477%) and stover (0.273%) results in higher uptake of phosphorus by seeds (7.56 kg ha-1) and stover (9.56 kg ha-1) of mungbean and showed significant superiority over rest of the treatments. However, 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg P2O5 ha-1 + Aspergillus awamori (F6) were statistically at par with each others with respect to phosphorus content and uptake by seeds and stover. Increase in seed and stover yield, which subsequently improved gross returns ( 1,31,440 and 1,20,787 ha-1), net returns ( 1,08,671 and 98,960 ha-1 ) and B: C ratio (5.77 and 5.53 ) and recorded highest under 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) followed by 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7), respectivelyThesisItem Open Access Effect of Weed Management Practices on Growth and Yield of Clusterbean [Cyamopsis tetragonoloba (L.) 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 on Growth and Yield of Pearl millet [Pennisetum glaucum (L.)

Wilczek] Varieties(Agriculture University, Jodhpur, 2020-07-20) Dev, Pushkar; Singh, Ummed; Ram, Moola; Singh, L. N.A field experiment was conducted at Instructional Farm, College of Agriculture, Jodhpur during kharif season of 2019 to study the “Optimization of Zinc in Mungbean [Vigna radiata (L.) Wilczek] Varieties”. The experiment was laid out in factorial randomized block design where in, four varieties of mungbean (‘GM 4, GAM 5, GM 6 and IPM 02-3’) and seven levels of zinc (control, 1, 2, 3, 4, 5 and 6 kg/ha) were undertaken and replicated thrice. Among mungbean varieties, ‘GM 6’ recorded substantially taller plants (48.88 cm), greater dry matter accumulation (20.15 g/plant), more number of primary (7.67/plant) and secondary branches (3.92/plant) at harvest stage of the crop. Further, the variety ‘GM 6’ also recorded significant improvement in number of nodules/plant (21.15 and 26.48) and nodule dry weight (47.59 and 73.19 mg/plant) at 25 and 50 DAS of growth stages over rest of the varieties. Likewise, crop growth rate at 25-50 DAS (17.60 g/m2 /day) and 50 DAS-at harvest (6.21 g/m2 /day) interval was also noticed significantly higher by the variety ‘GM 6’ over other varieties. Recording of SCMR and LAI at 25, 50 DAS and at harvest stage were also improved significantly by the variety ‘GM 6’ over other varieties and the values fetched were 43.08, 52.44 and 36.88 for SCMR and 0.67, 3.33 and 3.17 for LAI, respectively. Interaction effect of varieties and zinc levels on LAI in mungbean was found significant at 50 DAS growth stage, zinc application at 5 kg/ha with ‘GM 4’, GAM 5’, ‘GM 6’ and ‘IPM 02-3’ varieties were found significant interaction. Significant improvement in yield attributes of mungbean viz., pod length (10.42 cm), number of pods/plant (32.52), number of grains/pod (11.46) and 1,000- grains weight (50.63 g) were attained by the variety ‘GM 6’ over rest of the varieties undertaken in the experimentation. Similarly, significantly higher grain (1,313.72 kg/ha) and stover (3,016.63 kg/ha) yield were also recorded by the variety ‘GM 6’ over other varieties. Markedly higher zinc content at harvest stage in root (34.25 mg/kg) and leaf (38.40 mg/kg) were recorded by ‘IPM 02-3’, however, in stem (36.97 mg/kg) it was recorded by ‘GAM 5’. Further, substantially higher zinc content in grain (46.60 mg/kg) and stover (35.96 mg/kg) were recorded by the variety ‘GM 4’ over rest of the varieties. The same variety ‘GM 4’ also recorded statistically higher uptake of zinc by grains (52.07 g/ha) and stover (99.57 g/ha) over other varieties Economic evaluation of treatment (varieties) fetched highest gross return (`98,650/ha), net return (`77,176/ha) and B: C ratio (4.59) by ‘GM 6’ followed by ‘GM 4’ variety of mungbean. Among varying levels of zinc applied to mungbean, application of zinc at 5 kg/ha substantially enhanced growth attributes viz., plant height (15.00, 43.85 and 48.16 cm), dry matter accumulation (3.09, 15.58 and 19.41 g/plant), SCMR (42.70, 51.93 and 36.70), leaf area index (0.64, 3.45 and 3.28) at 25, 50 DAS and at harvest, respectively. Furthermore, crop growth rate (16.66 and 6.38 g/m2 /day), number of nodules/plant (21.81 and 26.65), nodules dry weight (48.23 and 73.82 mg/plant) at 25 and 50 DAS and number of primary and secondary branches (6.96 and 3.63/plant) at harvest stage were also recorded substantially higher over preceding levels of zinc. Moreover, significant improvement in yield attributing characters viz., pod length (9.97 cm), number of pods/plant (30.06), number of grains/pod (10.49), 1,000-grains weight (51.08 g), grain yield (1196.81 kg/ha) and stover yield (2861.93 kg/ha) were recorded with the application of zinc at 5 kg/ha over control and lower levels of zinc. Significantly higher zinc content in root (35.99, 16.91 and 26.49 mg/kg), stem (35.90, 23.18 and 27.73 mg/kg) and leaf (50.65, 56.87 and 35.50 mg/kg) at 25, 50 DAS and at harvest stage, respectively, were recorded with application of zinc at 6 kg/ha, the highest level of treatment. Additionally, significant improvement in zinc content in pod wall (21.18 mg/kg), grain (39.64 mg/kg) and stover (29.24 mg/kg) and N content in pod wall (0.82%), grain (3.92 %), stover (2.52%) and protein content (24.55%) in grain were also recorded with the highest dose of zinc applied at 6 kg/ha. Marked improvement in zinc uptake by grain (45.85 g/ha) and stover (82.72 g/ha) was recorded at 5 and 6 kg Zn/ha over preceded levels. All these improvements in terms of content, uptake and quality parameters were significantly higher over preceded levels of zinc. Interaction effect of varieties and zinc levels on N per cent in grain of mungbean was found significant. Zinc application at 6 kg/ha with ‘GAM 5’ and ‘IPM 02-3’ varieties were found significant interaction. Application of zinc at 5 kg/ha fetched gross return (`90,099/ha), net return (`68,174/ha) and B: C ratio (4.11) to the tune of 19.38, 24.31 and 0.45 per cent higher over control, respectively. Quadratic response function suggested highest response at optimum economic dose by the variety ‘IPM 02-3’ (220.99 kg/ha) followed by ‘GM 6’ (215.21 kg/ha), ‘GM 4’ (204.72 kg/ha) and ‘GAM 5’ (203.83 kg/ha).ThesisItem Open Access Efficacy of Herbicides in Kharif Groundnut (Arachis hypogaea L.)(Agriculture University, Jodhpur, 2020-07-15) ., Priyanka; Mehriya, M.L.; Shukla, U.N.; Singh, L. N.A field experiment was conducted at Agricultural Research station, Mandor, Agriculture University, Jodhpur during kharif, 2019 to study the “Efficacy of herbicides in kharif groundnut (Arachis hypogaea L.)”. The Field experiment was laid out in randomized block design (RBD) with thirteen treatments of replicated thrice. The treatments comprises of W1- Pendimethalin 30 EC at 1.0 kg/ha (PE), W2- Pendimethalin 38.7 CS at 1.0 kg/ha (PE), W3- Pendimethalin 30 EC + imazethapyr 2 EC at 1.0 kg/ha (PE) (ready-mix), W4- Imazethapyr 10 SL at 75 g/ha 20 DAS (PoE),W5- Imazethapyr + imazamox (pre-mix) at 70 g/ha 20 DAS, W6- Pendimethalin 30 EC at 1.0 kg/ha (PE) + imazethapyr at 75 g/ha 20 DAS, W7- Pendimethalin 30 EC at 1.0 kg/ha (PE) + quizalofop-p-ethyl at 50 g/ha 20 DAS W8- Sodium aciflourfen 16.5 % + clodinafop propargyl 8 % (ready-mix) at 200 g/ha 20 DAS, W9- Pendimethalin 30 EC + imazethapyr 2 EC at 1.0 kg/ha (PE) (ready-mix) + quizalofop p-ethyl at 50 g/ha 20 DAS, W10- Pendimethalin 30 EC at 1.0 kg/ha (PE) + manual weeding at 30 DAS, W11- Pendimethalin 30 EC + imazethapyr 2 EC at 1.0 kg/ha (PE) (ready-mix) + manual weeding at 30 DAS, W12- Weed free, W13- Weedy check. According to treatments, pendimethalin and its ready-mix with imazethapyr was applied as pre-emergence, while imazethapyr and its ready-mix with imazamox, quizalofop-p-ethyl and Sodium aciflourfen + clodinafop propargyl (ready-mix) were applied as post-emergence (20 DAS). Among treatments, application of pendimethalin + imazethapyr at 1.0 kg/ha (PE) + one manual weeding at 30 DAS and pendimethalin at 1.0 kg/ha (PE) + imazethapyr at 75 g/ha at 20 DAS significantly reduced weed density of broad leaved, grassy and sedge weeds and total weed dry matter at 30, 60, 90 DAS and at harvest. 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 Mungbean [Vigna radiata (L.) Wilczek](Agriculture University, Jodhpur, 2020) DANGA, MUKESH; Mehriya, M. L.; Shukla, U. N.; Meena, R. C.; Ram, MoolaA field experiment was conducted at Agronomy Farm, Agricultural Research Station, Mandor, Agriculture University, Jodhpur during kharif season of 2018 to study the “Efficacy of herbicides on growth and yield of mungbean [Vigna radiata (L.) Wilczek]”. The field experiment was laid out in randomized block design (RBD) with twelve treatments of replicated thrice. The treatments comprises of Weedy check, Weed free, Oxyfluorfen 50 g ha-1 (PoE), Oxyfluorfen 70 g ha-1 (PoE), Imazethapyr 60 g ha-1 (PoE), Imazethapyr 90 g ha-1 (PoE), Pendimethalin 750 g ha-1 (PE), Pendimethalin + Oxyfluorfen 400 g ha-1 (PE), Pendimethalin + Oxyfluorfen 550 g ha-1 (PE), Pendimethalin + Oxyfluorfen 750 g ha-1 (PE), Pendimethalin + Imazethapyr 800 g ha-1 (PE), Pendimethalin + Imazethapyr 900 g ha-1 (PE). According to treatments, pendimethalin and its ready mix with imazethapyr and oxyfluorfen were applied as pre-mergence (within 2 DAS), while alone imazethapyr and oxyfluorfen was applied as early post emergence (20 DAS). Pre emergence application of pendimethalin + imazethapyr 900 g ha-1 significantly reduced weed density and weed dry matter of monocot and dicot weeds at 30, 60 DAS and at harvest however, it was found at par with pre emergence application of pendimethalin + imazethapyr 800 g ha-1. 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 test weight of mungbean were produced significantly higher under pre emergence application of pendimethalin + imazethapyr 900 g ha-1. Due to better growth, higher value of yield attributes and lower weed index, this treatment caused to produce the maximum seed yield of 1197 kg ha-1 which was statistically at par with weed free plot (1206 kg ha-1) and pre emergence application of pendimethalin + imazethapyr 800 g ha-1 (1170 kg ha-1). The highest amount of total nitrogen uptake by crop (90.52 kg ha 1 ) was recorded with weed free treatment which remained at par with pre emergence application of pendimethalin + imazethapyr 900 g ha-1 (88.88) and pendimethalin + imazethapyr 800 g ha-1 (86.7 kg ha-1). The lowest amount of nitrogen removal by weeds was obtained with the pre emergence application of pendimethalin + imazethapyr 900 g ha-1 (2.88 kg ha-1). The highest net monetary returns and B:C ratio of ` 73037 and 4.08 were obtained with pendimethalin + imazethapyr (ready mix) 900 g ha-1 PE which was at par with its ready mix 800 g ha-1 PE.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. N.; Singh, Ummed; Choudhary, RakeshA field experiment entitled “Effect of stress mitigating chemicals and sulphur on growth and yield of mungbean [Vigna radiata (L.) Wilczek]” was conducted at Instructional Farm, College of Agriculture, Jodhpur (Rajasthan) during kharif season of 2019. 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 (C0), salicylic acid @ 75 ppm at flower initiation stage + 7 DAFS (C1), salicylic acid @ 75 ppm + 2% urea at flower initiation stage (C2), thiourea @ 500 ppm at flower initiation stage (C3) under stress mitigating chemicals, however, control (S0), 20 kg sulphur/ha (S1), 30 kg sulphur/ha (S2) and 40 kg sulphur/ha (S3) under levels of sulphur. Result indicated that application of thiourea @ 500 ppm at flower initiation stage (C3) of mungbean significantly higher growth attributes viz. plant height (12.66, 44.88 and 57.35 cm), dry matter accumulation/plant (1.61, 16.79 and 21.89 g), SPAD chlorophyll meter reading (41.64, 52.90 and 35.31) at 25, 50 DAS and at harvest, respectively, while number of nodules/plant (24.73), fresh weight of nodules/plant (277.51 mg), dry weight of nodules/plant (41.63 mg), primary branches/plant (7.77) and secondary branches/plant (4.82) as well as significantly increase yield attributing characters viz. pod length (10.40 cm), number of pods/plant (40.78), grains/pod (11.30) and 1000-grain weight (42.40 g) resulted in higher grain (1055 kg/ha), stover (2246 kg/ha) and biological yield (3301 kg/ha) along with harvest index (31.86%) followed by the treatment sprayed with salicylic acid @ 75 ppm + 2% urea at flower initiation stage. However, thiourea @ 500 ppm at flower initiation stage (C3) and salicylic acid @ 75 ppm + 2% urea at flower initiation stage (C2) were statistically at par with each others with respect to yield attributes and yield of mungbean. Similar trends were also observed with nitrogen and sulphur contents in grain (3.86 and 0.287%) and stover (1.45 and 0.116%) results in higher uptake of nitrogen and sulphur by grain (40.72 and 3.04 kg/ha) and stover (32.57 and 2.63 kg/ha), respectively as well as protein content (24.13%) of mungbean and showed significant superiority over rest of the treatments. Increase in grain and stover yield, which subsequently improved gross returns ( 78,870 and 77349/ha), net returns ( 55,031 and 53735/ha) and B: C ratio (3.31 and 3.28) due to application of thiourea @ 500 ppm at flower initiation stage (C3) and salicylic acid @ 75 ppm + 2% urea at flower initiation stage (C2), respectively. Results further revealed that among doses of sulphur, 40 kg sulphur/ha (S3) was remain at par with 30 kg sulphur/ha (S2) with respect to all parameters taken during experimentation. Application of 40 kg sulphur/ha (S3) significantly increased growth attributes mungbean viz. plant height (13.01, 43.44 and 54.48 cm), dry matter accumulation/plant (1.70, 16.38 and 21.69 g), SPAD chlorophyll meter reading (42.41, 52.27 and 34.52) at 25, 50 DAS and at harvest, respectively, while number of nodules/plant (25.17), fresh weight of nodules/plant (267.43 mg), dry weight of nodules/plant (40.62 mg), number of primary branches/plant (7.26) and secondary branches/plant (4.71) that enhanced yield attributing characters viz. pod length (10.35 cm),number of pods/plant (40.38), number of grains/pod (11.42) and 1000-grain weight (42.33 g) resulted in higher grain (1062 kg/ha), stover (2297 kg/ha) and biological yield (3359 kg/ha) along with harvest index (31.62%) over its lower dose i.e. 30 kg sulphur/ha (S2), 20 kg sulphur/ha (S1) and control (S0). It also recorded significantly higher nitrogen and sulphur contents in grain (3.73 and 0.269%) and stover (1.33 and 0.105%) results in higher uptakes of nitrogen and sulphur by grain (39.61 and 2.89 kg/ha) and stover (30.56 and 2.44 kg/ha), respectively as well as protein content (23.31%) of mungbean over rest of the treatments, but remained at par with 30 kg sulphur/ha (S2). Improvements in yield, of mungbean, which subsequently improved gross returns ( 79448 and 78355/ha), net returns ( 53603 and 53732/ha) and B: C ratio (3.07 and 3.18) under the treatment of 40 kg sulphur/ha followed by 30 kg sulphur/ha, respectively. On the basis of net return and B: C ratio, application of thiourea @ 500 ppm at flower initiation stage (C3) along with 30 kg sulphur/ha was more remunerative treatment in mungbean as compared to rest of the treatments.ThesisItem Open Access Micro-irrigation and Fertigation Management in Cumin (Cuminum cyminum L.)(Agriculture University, Jodhpur, Jodhpur, 2018-06-28) Mr. Kailash Chand Dalal; Dr. M L Mehriya; Bhardwaj R.L, Shukla U.N, and Raigar, P R
