Growth analysis in groundnut (Arachis hypogea L.) as influenced by Foliar nutrition
Abstract
A field experiment was conducted during kharif 2013 to Study “Foliar nutrition in groundnut (Arachis hypogea L.)’’at Main Agricultural Research Station, Dharwad under rainfed situation. The experiment was laid out in a randomized complete block Design (RCBD) with three replications and ten foliar treatments of major nutrients. The growth attributes such as plant height (23.94 cm), number of branches (7.82 plant−1), chlorophyll content (43.58), leaf area (8.90 dm2 plant−1), leaf area index (2.97), leaf area duration (40.69 days), total dry matter production (40.22 g plant−1), net assimilation rate (0.136 g dm−2day−1) and crop growth rate (0.124g dm−2 day−1) were higher in foliar spray of 2.0% urea + DAP + MOP combination (T8). Similarly, pod yield (3746 kg ha−1), kernel yield (2905 kg ha−1), haulm yield (4253 kg ha−1) and harvest index (0.36) were higher in foliar spray of 2.0% urea + DAP + MOP combinationat 45 DAS followed by foliar spray of 19: 19: 19 N: P2O5: K2O compared to control (No spray).
