ABSTRACT

A field experiment was conducted to study the efficacy of pre- and post-emergence herbicides and their combination to control the weed in soybean during summer season of the year 2014. Among the various herbicidal treatments Fluazifop-p-butyl @ 0.125 kg a.i./ha + Quizalofop ethyl @ 0.075 Kg a.i./ha (Tank mix) recorded lowest weed density (36.05/m2), dry matter (30.59 g/m2), weed index (10.78 %) and maximum weed control efficiency (64.38 %) at harvest. It also found superior in respect of yield attributes and highest seed yield (1101 kg/ha). Maximum gross monetary return (37102 Rs. /ha) and net monetary return (21000 Rs. /ha) and B:C ratio (2.30) were recorded in Fluazifop-p-butyl @ 0.125 kg a.i./ha + Quizalofop ethyl @ 0.075 Kg a.i./ha (Tank mix).
Key words: Herbicides, Sunflower, Seed Yield, Summer
