Effect of Date of Sowing and Integrated Nitrogen Management on Growth and Yield of Summer Groundnut (Arachis hypogaea L.)

A Field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to find out the Effect of Date of Sowing and Integrated Nitrogen Management on Growth and Yield of Summer Groundnut (Arachis hypogaea L.) The result showed that growth parameters of Groundnut viz., maximum plant height (72.00 cm), dry weight (41.54 g/plant), crop growth rate (15.05 g/m2/day), relative growth rate (0.014 g/g/day) and yield and yield attributes viz., number of pods/plant (48.00), number of seeds/pod (2.13), seed index (43.66 g), seed yield (3.14 t/ha), haulm yield (7.03 t/ha) and harvest index (30.62%) were recorded significantly higher with application of treatment 5 S1(1ST April) + 50% RDN (inorganic) + 50% RDN (Vermicompost). The maximum net returns (90,793 ₹/ha) and B:C ratio (2.73) was recorded with application of S1(1ST April) + 50% RDN (inorganic) + 50% RDN (Vermicompost).
