Root nodules, yield and quality of soybean (Glycine max L. merrill) as influenced by foliar application of growth regulator

Abstract

A field experiment was conducted during kharif season of 2015-16 on, yield and quality of soybean as influenced by growth regulator, at farm department of soil science and agricultural chemistry, college of agriculture Latur. This experiment was laid out in randomized block design with eight treatments of foliar application of growth regulator (NAA and GA) and KNO3 with RDF. The maximum no of root nodules, fresh and dry weight of root nodules, yield and quality attributes of soybean was found at application of RDF+ NAA @ 40 ppm + GA3 @ 40 ppm (20 and 35 DAS) + KNO3 @1% (30, 45 and 60) was found significantly superior over RDF alone. This showed that the foliar application of growth regulator NAA @ 40 ppm + GA3 @ 40 ppm (20 and 35 DAS) + KNO3 @1% (30, 45 and 60) along with RDF enhancing root nodules, yield and quality attributes of soybean.
