Title: Weed management by sowing methods and herbicides in soybean
Abstract: A field experiment was conducted at Jabalpur to evaluate the different sowing methods and weed control practices for higher grain yield of soybean. The dominated weed species among monocot weeds were Cyperus iria, Ehinochloa colona and Cynodon dactylon, however among dictot weed species Eclipta alba, Commelina diffusa, Alternenthera sessilis and Phylanthus niruri were observed during the growing season.The results revealed that the weed density of monocot (25.1/m2) and dicot (18.7/m2) weed was lowest in broad bed furrow (BBF) sowing method and application of pendimethalin (0.75 kg/ha) fb imazethapyr (0.75 g/ha. Maximum weed control efficiency (80.0%) was observed with the application of pendimethalin (0.75 kg/ha) fb imazethapyr (0.75 kg/ha). BBF sowing method also recorded highest yield attributes and grain and straw yield (1.47 and 1.51 t/ha). The BBF sowing method of soybean gave maximum net monetary returns and B:C ratio (`16,584/ha and 1.87, respectively).
