An experiment was conducted at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during summer season of the year 2019 to study Effect of irrigation scheduling and nitrogen management on growth and yield of summer groundnut (Arachis hypogaea L.). The experiment were four irrigation schedules (IW: CPE ratios 0.4, 0.6 and 0.8 and irrigation at critical growth stages flowering, branching, pod formation and pod development stages) and five nitrogen management treatments were tried. Irrigation level I? (0.8 IW: CPE ratio) recorded higher pod yield and haulm yield, nitrogen content in seed and haulm, nitrogen uptake by seed and haulm. The highest water use efficiency was recorded under treatment I?. Nitrogen management treatment N? (50% RDN through chemical fertilizer + 50% RDN through vermicompost) recorded significantly increase pod yield, haulm yield, nitrogen content in seed and haulm, nitrogen uptake by seed and haulm. The treatment combination I?N? recorded higher pod yield, haulm yield, nitrogen uptake by seed and haulm, net realization. Significantly higher WUE was recorded under treatment combination I?N?.
