Integrated Nutrient Management on Yield Maximization of Irrigated Groundnut

A field experiment was conducted during rabi-summer season of 2009–10 and 2010–11 at Agronomy Main Research farm, Orissa University of Agriculture and Technology, Odisha to study the effect of integrated nutrient management on maximizing the yield of groundnut crop under irrigated condition. The result of pooled analysis of two years data revealed that application of 100% recommended dose of fertilizer as basal plus 50% recommended dose of fertilizer nitrogen at 30 DAS along with FYM @7.5t/ha recorded the maximum pod yleld of 2200kg/ha which was comparable with 75% recommended dose of fertilizer as basal and 75% recommended dose of fertilizer nitrogen at 30DAS with or without FYM @7.5 t/ha and 100% recommended dose of fertilizer as basal plus 50% recommended dose of fertilizer nitrogen at 30 DAS without FYM@7.5 t/ha. The yield maximization was due to improvement in growth parameters and yield attributes. Similar trend was also observed in respect of maximum gross return (Rs. 48629/ha), net return (Rs. 23274/ha) and benefit-cost ratio (1.935) with the same treatment.
