Synergistic effects of integrated nutrient management and gypsum on productivity and profitability of Groundnut [Arachis hypogaea (L.)]

A field study was carried out during the kharif season of 2024 at the Agricultural Research Farm of Suresh Gyan Vihar University, Jaipur (Rajasthan) on loamy sand soil. The experiment was laid out in factorial randomized block design with integrated nutrient management practices and gypsum levels in groundnut. The experiment consisted sixteen treatments viz., two factors with where 4 levels of integrated nutrient management and four levels of gypsum with three replications, using groundnut variety ‘HNG‑10’. Results clearly showed that application of N3: 75% RDF+2.5 ton/ha significantly increased plant height at harvest, plant dry matter at harvest, LAI, pod yield, haulm yield, protein and oil content registered over control. However; highest net returns and B:C was significantly increased due to application of N2: 50% RDF+5 ton FYM over control. Furthermore, application of G3: 250 kg/ha recorded significantly higher growth, yield and quality parameters over control. Further; net returns and B:C were also affecting significantly highly under G3: 250 kg/ha.
