Effect of foliar nutrition on, light interception, production efficiency, productivity rating index and energetic of soybean [Glycine max (L.) Merrill]

Abstract

The present investigation entitled ‘‘Effect of foliar nutrition on light interception, production efficiency, production rating index and energetic of soybean [Glycine max (L.) Merrill]’’ was carried out at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur during Kharif season of 2016. Experiment was laid out in Randomized Block Design (RBD) with three replications. The soybean variety JS-97 52 tested under different foliar application of nutrients. The result revealed application of RDF + spray of DAP @ 2% at pre flowering and pod initiations stages of crop resulted significantly higher percentage of Productivity rating index and production efficiency. The higher Energy use Efficiency (MJ 10-3 ha-1) recorded under the spray of RDF + Urea 2% spray at pod initiation and light interception getting non-significant of all the treatments.
