Effect of irrigation scheduling and nutrient management on yield, water use efficiency and economics in garden pea (Pisum sativum L.)

Abstract

A field experiment was carried out at Palampur during the rabi season of 2017-18 with 12 treatment combinations of three irrigation levels (I1: Irrigation at 15 days interval at 0.8 CPE Cumulative pan evaporation), I2: Irrigation at 15 days interval at 0.6 CPE and I3: Rainfed) and four nutrient management practices (F1:100% NPK through inorganic sources, F2:10 t FYM + Rhizobium + Jeevamrit at 21 days interval, F3: 5 t FYM +50% NPK through inorganic source and F4:Zero budget farming (seed treatment with Bijamrit + Jeevamrit at 21 days interval) and control (Recommended package of practice + flood irrigation at 10 days interval). Water use efficiency (WUE) was significantly higher under rainfed condition. The higher yield attributes, yield, WUE and net returns were obtained with an irrigation.
