Yield and economics of green gram (Vigna radiata L.) as influenced by foliar application of nano urea and nano-DAP

Abstract

A field experiment was conducted during Kharif 2024 at the Experimental Farm, Department of Agronomy, VNMKV, Parbhani, to evaluate the effect of foliar-applied nano urea and nano-DAP on the performance of green gram (Vigna radiata L.). The experiment was laid out in a randomized block design with seven treatments and three replications. The treatments comprised of different combinations of RDF (Recommended Dose of Fertilizer) with foliar applications of nano urea and nano-DAP. The results of the experiment revealed that application of 25:50:25 NPK kg ha⁻¹ (100% RDF) recorded significantly higher yield attributes, seed yield and economic returns of green gram, however it was comparable with 75% RDF + 0.4% nano urea at 25 DAS + 0.4% nano DAP at 45 DAS and 75% RDF + 0.4% nano DAP at 45 DAS.
