Effect of Irrigation Scheduling and Foliar Organic Nutrition on Growth and Yield of Summer Groundnut (Arachis hypogaea L.)

Abstract

A field experiment was conducted during summer season of 2022 at Crop Research Farm (CRF). Department of Agronomy, SHUATS, Prayagraj (UP) on soil with sandy loam in texture with Organic carbon 0.48%, Available Nitrogen 278.93 Kg/ha, Available Phosphorus 19.03 Kg/ha, Available Potassium 238.1 Kg/ha, Soil Ph 7.4, EC 0.47 ds/m to investigate the effect ofrrigation scheduling and foliar organic nutrition on growth and yield of Zaid Groundnut. The treatments consist of three irrigation schedulings viz., I1: 3 irrigations (25,45,70 DAS), I2: 2 irrigations (25,45 DAS), I3: 2 irrigations (25,70 DAS) and three foliar organic nutrition F1 – Panchagavya at 3%, F2 – Jeevamrutha at 3%, F3 – Panchamrutha at 3% whose effect is observed on Groundnut (var. Kadiri-6). The experiment was laid out in randomized block design with ten treatments replicated thrice. The treatment with application of 3 irrigations (25,45,70 DAS) + panchagavya-3% recorded significantly higher plant height (60.07cm) and plant dry weight (39.62 g), number of pods per plant (20.33), number of kernels per pod (2.47), seed index (39.84  g), pod yield (2.85 t/ha) and haulm yield (4.4 t/ha) compared to other treatment combinations. It is concluded that 3 irrigations (25,45,70 DAS) and panchagavya-3% accomplished better growth parameters, yield attributes and higher pod yield in groundnut crop.
