ABSTRACT
A field experiment was conducted during rainy season (kharif) of 2015 at College Farm, Agricultural College, Polasa, Jagtial to find out the effectiveness of sequential application of herbicides in soybean (Glycine max (L.) Merril). Pre emergence of (PE) application of pendimethalin @ 2.5 l/ha followed by imazethapyr @ 75 g/ha at 20 DAS resulted in the lowest weed dry matter and maximum weed control efficiency followed by PE application of pendimethalin @ 2.5 l/ha followed by imazethapyr + imazamox @ 100 g/ha at 20 DAS. This treatment also recorded highest seed yield of soybean and also it was found to be economical with high B:C ratio.
Key words: Herbicides, Pre-emergence, Post-emergence, Soybean, Weed management, Yield.
