A field experiment was carried out during kharif, rabi and zaid seasons of 2015-16 and 2016-17 to study the effect of soybean [Glycine max (L.) Merrill] based cropping systems on weed dynamics and productivity of soybean and subsequent crops of the system at the research farm of Krishi Vigyan Kendra, Dhar, . Among the all 16 soybean based cropping systems under Kharif, in soybean Echinochloa crusgalli was the most dominating weed contributing % of total weed intensity at most critical period (25 DAS) while Celosia argentea topped at harvest stage ( %). | Effect of soybean [Glycine max (L.)
