Abstract:
A field experiment was carried out during Rabi season 2017 at the Agrometeorological research farm of College of Agriculture, Orissa University of Agriculture and Technology, Bhubaneswar to evaluate the adequate effect of irrigation & mulching on groundnut (Arachis hypogaea L.) productivity. The experiment was laid out in split plot design with three irrigation levels (I1- Irrigation on 25, 45 & 70 DAS, I2- Irrigation on 25 & 45 DAS & I3- Irrigation on 25 & 70 DAS) as main plots whereas mulching (M1- Mulching with paddy straw, M2- Mulching with FYM @ 5t/ha & M3- No mulch) as sub plots consisting of three replications. I1-Irrigation on 25, 45 & 70 DAS produced highest plant height (57.4cm), more number of pods/plant (14.7), number of seeds/plant (24.2) and dry weight of seeds/plant (9.7gm) whereas more dry weight of pods/plant (14.1gm), fresh weight of pods/ha (2303kg/ha), yield (1161kg/ha), biological yield (8287kg/ha) and harvest index (14.15%) were recorded significantly in treatment I3- Irrigation on 25 & 70 DAS. In M2- Mulching with FYM @ 5t/ha recorded highest in number of pods/plant (14.8), dry weight of pods/plant (14.5gm), number of seeds/plant (22.3), dry weight of seeds/plant (10.3gm), fresh weight of pods/ha (2303kg/ha), yield (1124kg/ha), biological yield (8505kg/ha) and harvest index (13.45%) whereas M1- Mulching with paddy straw recorded highest plant height (59.0cm).
