Organic and Inorganic Weed Management Practices in Soybean Under Different Land Configurations

The present research work was conducted in monsoon season during 2022–23 for three different land soil bed preparations (land configurations). The study aims to investigate influence of microclimate and weed management approaches on soybean growth and productivity. The experimentation was in split plot technique with main plot treatments comprised of three land configurations (two row broad bed furrow, four row broad bed furrow, flat bed) and four different techniques to control weeds (PE Sulfentrazone 28% + Clomazone 30% WP 350 + 375 g.a.i./ha, PoE Fomesafen 12% + Quizalofop ethyl 3% w/w SC @180 + 45 g.a.i./ha, weedy check and mechanical weeding) in sub plot replicated three times. The results indicated that growing soybean on BBF of four rows (L2) and two row BBF (L1) was productive as well as profitable and found efficient in storing more soil moisture and maintaining canopy temperature over sowing soybean on flat. The lowest weed population of both monocot and broad leaf weeds as well as more soybean seed yield was observed in mechanical weeding and PoE Fomesafen 12% + Quizalofop ethyl 3% w/w SC @ 180 + 45 g.a.i./ha.
