Interaction effect of irrigation scheduling, mulching and integrated nutrient management on summer groundnut (Arachis hypogaea L.) yields under subtropical conditions of eastern Uttar Pradesh

Abstract

The study aimed to evaluate the interaction effect of irrigation scheduling, mulching and integrated nutrient management on yields of summer groundnut under sub-tropical condi-tions. An experiment of summer groundnut involving three irrigation scheduling, two mulching and four integrated nutrient management treatments was undertaken for con-secutive two years at Agricultural Research Farm, Institute of Agricultural Sciences, Ba-naras Hindu University, Varanasi, India in a split-plot design with three replications Treat-ments significantly influenced pod, kernel, haulm, and biological yield of groundnut. Irriga-tion scheduling at 60 CPE (cumulative pan evaporation) with paddy straw mulch and 75% recommended dose of nitrogen (RDN) + 25% N through farmyard manure (FYM)] + 60 kg S through gypsum recorded highest pod (3611 kg ha-1), kernel (2254 kg ha-1), haulm (5185 kg ha-1), and biological yield (8743 kg ha-1). Further this treatment combination was found better for increasing summer groundnut yields under subtropical conditions.
