Growth analysis in groundnut (Arachis hypogea L.) as influenced by Foliar nutrition
2017
Kumar, H.M Vinod | Salakinkop, S.R.
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).
