Abstract:

A field experiment was conducted during Kharif season of 2009-10 at Research Farm, Adhartal, JNKVV, Jabalpur to study the effect of early post-emergence herbicides against weeds in soybean (Glycine max L.). The density and dry weight of weeds were higher under weedy check treatment. However, identical reduction in density and dry weight of weeds were observed when weeds were controlled chemically. Significantly higher weed control efficiency (81.82%) and seed yield (2.9 t/ha) was observed under Odyssey (mixture of imazethapyr + imazamox) + adjuvant (87.5 g + 1000 ml/ha). The maximum net profit ( 43233/ha) and B: C ratio (3.67) were also recorded under the same treatment.
