Abstract
A field experiment entitled, “Effect of land configuration and weed management on mungbean productivity under temperate conditions of Kashmir” was conducted during Kharif seasons of 2014 and 2015 under AICRP on MULLaRP. The soil of the experimental field was silty clay in texture, low in organic carbon and medium in nitrogen, phosphorus potassium. The experiment consisted of two treatments of land configuration viz., Flat Bed Method (FBM) and Ridge method (RM) in main plot and four weed management treatments viz., Weedy check, Pendimethalin @ 1.0 kg a.i/ha PE, Imazethapyr 10 % SL @ 55 g/ha at 15 – 20 DAS and Pendimethalin 30 EC PE fb imazethapyr 10 % SL @ 55 g/ha at 15-20 DASlaid out in strip plot design (SPD) with three replications. The experimental results revealed that the grain yield of Flat Bed Method (L1) was at par with Ridge Method (L2) and there was non-significant difference with respect to yield attributing characters. Weed density (No./m2) and weed dry matter (g/m2) also exhibited non-significant difference at 30 and 60 days after sowing (DAS) of crop. Among weed management practices, weedy check recorded the lowest grain yield of 552 kg/ha and showed significant difference when compared with rest of the treatments, whereas highest grain yield of 818.75 kg/ha was recorded with pendimethalin 30 EC @ 1.0 kg/ha-PE followed by imazethapyr 10 % SL @ 55 g/ha at 15-20 DAS, imazethapyr 10 % SL @ 55 g/ha at 15-20 DAS and pendimethalin 30 EC @ 0.75/1.0 kg a.i /ha PE in decreasing order. Pendimethalin 30 EC @ 1.0 kg/ha-PE fb Imazethapyr 10 % SL @ 55 g/ha at 15-20 DAS, imazethapyr 10 % SL @ 55 g/ha at 15-20 DAS and Pendimethalin 30 EC @ 0.75/1.0 kg a.i /ha PE recorded 48.04 %, 33.92% and 18.62% increase in grain yield respectively than weedy check. The major weeds identified in the experimental field were Cynodon dactylon, Sorghum halepense, Conyza spp., Matricaria spp., Poa spp. among Grassy weeds; Convolvulus arvensis, Amaranthus viridis, Chenopodium album among broadleaved weeds and Cyperus rotundus among sedges. Highest monetary returns and B: C ratio (Rs. 68500/ha and 1.96) was recorded in pendimethalin 30 EC @ 0.75/1.0 kg a.i. /ha PE fb imazethapyr 10 % SL @ 55 g/ha at 15-20 DAS (W4) and lowest monetary returns and B: C ratio (Rs. 46160/ha and 1.07) was recorded in weedy check. Among weed management practices, uncontrolled weedy check resulted in 32.58 per cent reduction in grain yield of mungbean.
