Effect of supplemental nitrogen sources and fertilizer nitrogen on weed density and growth in maize+soybean-wheat cropping sequence

Field experiment conducted during 1983–84 and 1984–85 a(Hiftiachaf Pradesh Krishi Vishvavidyalaya, Pafempur, revealed that the application! of FYM either alone or in combinationwiih biofertilzer or homoeopathic fertilizer resulted irt significantly more weed density and their growth interms of drymatter accumulation. Increase in nitrogert upto 120kg/hs increased the weed growth significantly during, both the years of experimentation
