    Herbicidal weed management in chickpea (Cicer arietinum L.)
    (Agriculture University, Jodhpur, 2022-07-25) Yadav, Manisha; Singh, Ishwar
    A 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.

    A 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. 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.

    A field experiment entitled “Effect of seed priming and foliar spray of stress mitigating chemicals on growth and yield of mungbean [Vigna radiata (L.) Wilczek] varieties” was conducted at Instructional Farm, College of Agriculture, Jodhpur (Rajasthan) during kharif season of 2022. Field experiment was laid out in factorial randomized block design (FRBD) with twelve treatment combinations and replicated thrice. The two factor were taken in the investigation, Factor A having two varieties i.e., ‘GM-7’ (V1) and ‘MH-421’(V2) and Factor B having six treatments viz. control (C0), seed priming with thiourea @ 500 ppm (C1), seed priming with salicylic acid @ 75 ppm (C2), seed priming with thiourea @ 500 ppm + foliar spray @ 500 ppm at flower initiation stage (C3), seed priming with salicylic acid @ 75 ppm + foliar spray @ 75 ppm at flower initiation stage (C4) and seed priming with salicylic acid @ 75 ppm + foliar spray @ 75 ppm + 2% urea at flower initiation stage (C5) under stress mitigating chemicals. Results indicated that variety ‘MH-421’(V2) recorded significantly higher growth attributes viz. dry matter accumulation/plant (3.91, 14.55 and 25.73 g/plant), number of trifoliate leaves/plant (13.62 and 9.88), chlorophyll content (2.25 and 1.24 mg/g), root length (12.5 and 14.5 cm), root volume (5.66 and 9.72 ml) and number of major rootlets/plant (13.68 and 15.82) at 50 DAS and at harvest stage and total number of branches/plant (6.2 and 7.4) at 50 DAS and at harvest stage and number of nodules/plant (30.09) and dry weight of nodules (93.09 mg/plant) at 50 DAS as well as significantly increase yield attributing characters viz. pod length (10.6 cm), number of pods/plant (28.5), number of grains/pods (10.2) and 1000-grains weight (39.48 g) resulted in higher grain yield (1025 kg/ha), stover yield (2361 kg/ha), biological yield (3386 kg/ha) and harvest index (30.27%) as well as protein content (23.31%) and protein yield (238.92 kg/ha). 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.

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), respectively

    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.
