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, M.P. Among the all 16 soybean based cropping systems under Kharif, in soybean Echinochloa crusgalli was the most dominating weed contributing 27.35 % of total weed intensity at most critical period (25 DAS) while Celosia argentea topped at harvest stage (28.9 %). | Effect of soybean [Glycine max (L.)
