Abstract:
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 soil of experimental field was loamy sand in texture having good drainage, low in available nitrogen (166.52 kg/ha), low in available phosphorus (44.53 kg/ha) and medium in available potassium (286.28 kg/ha) with 8.15 soil ph. 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 viz. N₀ (Control), N₁ (100% RDN through chemical fertilizer), N₂ (75% RDN through chemical fertilizer + 25% RDN through vermicompost), N₃ (50% RDN through chemical fertilizer + 50% RDN through vermicompost), N₄ (100% RDN through vermicompost) were tried. Higher value growth characters and yield characters were recorded under treatment I₂ (0.8 IW: CPE ratio). Nitrogen management treatment N₃. (50% RDN through chemical fertilizer + 50% RDN through vermicompost) recorded significantly increase growth characters, pod yield and haulm yield. The treatment combination I₂N₃ (0.8 IW: CPE ratio and 50% RDN through chemical fertilizer + 50% RDN through vermicompost) recorded higher pod yield and Haulm yield.
