Abstract
A field experiment was carried out during kharif season of 2010 at Mirzapur (Uttar Pradesh) to determine the effect of inorganic fertilizers and organic manure on growth, yield and nutrient uptake by green gram (Vigna radiata L. cv. HUM-12). Integrated application of 50% RDF + 100% poultry manure (T6) recorded significantly higher dry matter (39.11 g plant-1), seed yield(1002 kg ha-1), straw yield(3102 kg ha-1) and nutrient uptake in grain (28.13, 3.72 and 10.06 NPK kg ha-1, respectively) of greengram, consequently resulted maximum gross return (75110 ha-1), net return (59263 ha-1) and benefit: cost ratio (4.56). Thus, combined application of inorganic fertilizer and organic manure was found to be the best for higher productivity and profitability of greengram cultivation in custard apple-based agri-horti system under rainfed condition.
