ABSTRACT
A field experiment was conducted during kharif season of 2015 at College Farm, Agricultural College, Polasa, Jagtial to study the effect of sequential application of pre and post-emergence herbicides on growth, yield attributes and yield of soybean (Glycine max (L.) Merril). Among these sequential treatments, Growth parameters, yield attributes and yield of soybean was higher with the Pre emergence of (PE) application of pendimethalin @ 2.5 l/ha followed by imazethapyr @ 75 g/ha at 20 DAS (T12) followed by PE application of pendimethalin @ 2.5 l/ha followed by imazethapyr + imazamox @ 100 g/ha at 20 DAS (T8). This treatment also recorded highest seed yield of soybean with taller plants, more number of pods/plant and seeds/pod. The test weight was not influenced by the herbicides. Similarly, Pre emergence of (PE) application of pendimethalin @ 2.5 l/ha followed by imazethapyr @ 75 g/ha at 20 DAS (T12) was found to be economical with high B:C ratio.
Key words: Herbicides, Pre-emergence, Post-emergence, Yield attributes, Soybean, Yield.
