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

A Field experiment was conducted during Zaid 2022 with a goal to evaluate the effect of date sowing and integrated nitrogen management on growth yield summer groundnut (Arachis hypogaea). The laid out in Randomized Block Design ten treatments each replicated thrice at Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology Sciences (SHUATS), Prayagraj - 211007, (U.P.) which is located 25.28oN latitude, 81.54oE longitude 98 m altitude above Mean Sea Level (MSL) for 100 days. soil experimental plot sandy loam texture, nearly neutral reaction (pH 7.4), low organic carbon (0.58%), available N (225 kg.ha-1), P (32.30 kg.ha-1) K (350 kg.ha-1). treatment consists 5 levels INM [100% RDN through inorganic, 100% FYM, Vermicompost, 50% (inorganic) + (FYM), (Vermicompost)] as basal application 2 Dates Sowing (1st 15th April), whose observed groundnut. result showed that parameters Groundnut viz., maximum plant height (72.00 cm), dry weight (41.54 g/plant), crop rate (15.05 g/m2/day), relative (0.014 g/g/day) attributes number pods/plant (48.00), seeds/pod (2.13), seed index (43.66 g), (3.14 t/ha), haulm (7.03 t/ha) harvest (30.62%) recorded significantly higher S1(1ST April) (Vermicompost). net returns (90,793 ₹/ha) B:C ratio (2.73)
