Productivity of Irrigated Groundnut as Influenced by Potassium and Sulphur Nutrition in Sandy Clay Loam Soil

Field experiments were conducted during the Kharif and rabi season of 2021 in farmer’s field Perampattu Village, Tirupattur Taluk & District, TN, India to study effect K S management groundnut. The soil experiment belongs sandy clay loam, available nitrogen (133.4 kg ha-1), phosphorus (16.8 potassium (113.1 sulfur (4.80 mg kg-1), respectively. laid out Randomized Block Design (RBD) with eight treatments viz., T1-Control, T2–RDF (Blanket Recommendation as 25:50:75 NPK T3- RDF + Add 0.25% through MOP (Foliar Application), T4– 0.5% T5– SOP T6– T7– KNO3 T8– Application) replicated thrice. Higher yield groundnut 3103 Kg ha-1 2895 ha-1, respectively, percent increase T4 was 3.9 5.63 over other also maximum gross income, net benefit-cost ratio obtained (T4) applied treatment both seasons. lowest achieved T1.
