A field experiment was conducted during the rainy season of 2006 at Instructional farm, College of Agriculture, Junagadh Agriculture University, Junagadh on clayey soil to study the efficacy of post-emergence herbicides on soybean under different fertility levels and their residual effects on succeeding crops of sorghum, bajra, barley and ragi. Among the weed management practices, the weed free treatment produced significantly higher grain yield (2336 kg/ha) and stover yield (2772 kg/ha). The next best treatment to control the weeds at initial growth stage was pendimethalin 0.5 kg/ha pre-em + HW + IC at 30 DAS. The treatment imazethapyr 75 g/ha post-em. at 25 DAS +HW +IC 45 DAS ) recorded the lowest no. of weeds/m2. Among the fertilizer levels the treatments F3 40:80:40 and F2 30:60:30 N, P2O5, K2O kg/ha recorded equally the higher grains (2006 kg/ha and 1973 kg/ha) and stover yield (2321 kg/ha and 2228 kg/ha, respectively).The crops like sorghum, bajra, barley and ragi can be sown safely as succeeding crops after harvesting the kharif soybean. In soybean the effective weed management up to 60 DAS and fertilizing the crop with 30:60:60 N, P2O5, K₂O kg/ha gave higher grains and stover yield and had no residual effect on succeeding crops
