Enhancing productivity and nutritional quality of groundnut (Arachis hypogaea l.) through foliar nutrition

Abstract

The field experiment was conducted during kharif to study “Foliar nutrition in groundnut (Arachis hypogaea L.) At under rainfed situation. The experiment was laid out in a Randomized Complete Block Design with three replications and ten foliar treatments of major nutrients.Among the various foliar treatments net returns ( ₹ 108730 ha-1) and B: C ratios (4.12) were the higher in foliar spray of 2.0% urea + DAP + MOP combination at 45 DAS followed by foliar spray of 19:19:19 ( ₹ 108095ha-1 and 4.12, respectively). Similarly, yield parameters and yield such as 100 pod weight (117.65 g), total number of pods plant-1 (28.37), 100 kernel weight (42.19 g), pod yield (3746 kg ha-1), kernel yield (2905 kg ha-1), haulm yield (4253 kg ha-1) and harvest index (0.36) were also higher in foliar spray of 2.0% urea + DAP + MOP.Oil content (46.73%), protein content (27.65), oil yield (1356kg ha-1) and nutrient uptake (209.66 kg N, 32.25 kg P2O5, and 357.95 kg K2O) were significantly higher in foliar treatment compared to control.
