Influence of planting geometry on growth, yield and nutrient uptake of groundnut (Arachis hypogaea L.) cultivars under broad bed and furrow system

A field study on “Influence of Planting Geometry on Growth, yield and Nutrient Uptake of Groundnut (Arachis hypogaea L.) under Broad Bed and Furrow System” was conducted during rabi season of 2022-23 at the research field of International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Hyderabad, India. The experiment was laid out with 2 × 4 factorial randomised block design with three replications on broad bed furrow. Total sixteen treatment combinations consisted of four planting geometries: 30 cm × 10 cm (P1), 15:15 cm × 10 cm (P2), 20:20 cm × 10 cm (P3), 25:25 cm × 10 cm (P4) in paired row was the first factor and second factor includes four genotypes which were Girnar 4 (V1), Girnar 5 (V2), Avtar (V3), K6 (V4). Among the planting geometries, leaf area index, dry matter production was significantly higher in 25:25 × 10 cm while number of branches plant-1 was found non-significant. Pod yield and nutrient uptake was significantly influenced by 25:25 × 10 cm planting geometry as compared to the other planting geometries. Among the varieties studied, Girnar 5 variety recorded higher plant height, leaf area index, dry matter production, yield and nutrient uptake and it was on par with Girnar 4. From this investigation it can be concluded that, among the planting geometries, 25:25 × 10 cm spacing found best compared to other planting geometries and among the varieties studied Girnar 5 and Girnar 4 varieties were found best among varieties studied.
