Response of groundnut (Arachis hypogaea L.) to foliar nutrition of urea phosphate

A field investigation entitled “Response of Groundnut (Arachis hypogaea L.) to foliar nutrition of urea phosphate” was conducted in summer season of 2024 at the AICRP on Groundnut, Mahatma Phule Krishi Vidyapeeth, Rahuri to study effect of foliar nutrition of urea phosphate in summer groundnut. The experiment was laid out in randomized block design (RBD) with three replications. The experiment consists of eight treatments viz., The experiment consists of eight treatments viz, T₁: 100% RDNP, T₂: 75% RDNP, T₃: T₁ + Foliar application of urea phosphate @ 1% at flowering and peg formation stage, T₄: T₁ + Foliar application of urea phosphate @ 2% at flowering and peg formation stage, T₅: T₂ + Foliar application of urea phosphate @ 1% at flowering and peg formation stage, T₆: T₂ + Foliar application of urea phosphate @ 2% at flowering and peg formation stage, T₇: T₁ + Foliar application of DAP @ 2% at flowering and peg formation stage, T₈: T₂ + Foliar application of DAP @ 2% at flowering and peg formation stage. As regards yield attributing characters, significantly higher dry pod yield (40.11 q ha^-1), kernel yield (25.99 q ha^-1), haulm yield (49.07 q ha^-1), biological yield (89.18 q ha^-1) were recorded under treatment T₄: 100% RDNP+ Foliar application of urea phosphate @ 2% at flowering and peg formation stage Significantly the highest gross monetary returns (₹188848ha^-1) was obtained in T₄: 100% RDNP+ Foliar application of urea phosphate @ 2% at flowering and peg formation stage which also recorded a significantly maximum net monetary returns (₹124884ha^-1) and B:C ratio (2.95) than other treatments. While, T₂: 75% RDNP obtained minimum gross monetary returns, net monetary returns and B:C ratio among all the treatments.
