摘要

A field experiment was conducted during rainy season of 2009-10 at Research Farm, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to study the bio-efficacy of post-emergence herbicides on weeds in soybean. Earlypost-emergence applications of imazethapyr with adjuvant and ammonium sulphate (100 g + 750 ml + 1 kg/ha) was most effective in paralyzing the weed growth and producing significantly higher yield attributing characters and seed yield (2.6 t/ha). The sametreatment recorded the maximum net monetary returns ( 39,109/ha) and B:C ratio (3.20). The minimum seed yield (1.3 t/ha) was recorded under weedy check.
