Abstract

A field experiment was conducted during kharif season 2012 and 2013 at Rajmata Vijayaraje Scindia Krishi Vishwa Vidhyalaya RVSKVV, College Farm Gwalior (M.P.) to asses the suiTable method for weed control in soybean. On the basis of two years pooled data results weeding twice at 20 and 40 DAS significantly highest growth, yield attributes and seed yield as compared to the un-weeded control and was at par with pendimethalin (750 g a.i./ha) + one hand weeding, trifluralin (1000 g a.i./ha) + one hand weeding at 20 DAS and imezathapyr(100 g a.i./ha) + one hand weeding at 40 DAS. These treatments also recorded lower weed dry biomassand higher weed control efficiency.  Pendimethalin (750 g a.i./ha) + one hand weeding at 20 DAS resulted higher net return (` 63500) and B:C  (2.58) ratio followed by trifluralin + one hand weeding and hand weeding twice at 20 and 40 DAS. In addition to hand weeding twice, pre emergence herbicide Pendimethalin (750g a,i/ha) + one  hand weeding at 20 DAS can be effectively used as an alternative for controlling weeds for obtaining optimum seed yield in soybean.
