Abstract:
A field experiment was carried out at the Breeder Seed Production Unit, Department of Agronomy, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) during the 2019 Kharif season, to assess the density and weed control effectiveness, as well as the bio-efficacy of herbicide combinations against mixed weed flora. The findings showed that monocot weeds like Echinochloa colona (44.7%) were the most common weeds in the experimental field. However, other monocot weeds like Cyperus iria (10.91%), Commelina benghalensis (13.36%), and dicot weeds like Alterenanthera philoxiroides (15.12%) and Mollugo pentaphylla (16.54%) were also associated with soybean in lesser numbers. When Fenoxaprop-p-ethyl 6% + Chlorimuron ethyl was applied post-emergence, the reduction in weed density and dry weight was more noticeable.
