Effect of seed pelleting and foliar nutrition on root characters, nutrient uptake and yield of summer irrigated sesame


Author(s): Teresa Alex and Dr. K Srinivasan

Abstract: A field experiment was conducted during 2017, to investigate the effect of seed pelleting and foliar nutrition on root growth, nutrient uptake and yield of summer irrigated sesame (Sesamum indicum. L). The experiment was laid out in factorial randomized block design with three replications. Seed pelleting and foliar nutrition were the two factors. Pelleted and non pelleted seeds were the two levels of seed pelleting. Foliar nutrition comprised of Urea (1%), DAP (1%), 19:19:19 (NPK) (1%), MnSOâ‚„ (0.5%), MAP (0.5%), Combined nutrient spray (2%), Salicylic acid (100 ppm) and Control (no spray), which were sprayed at 30 and 45 DAS. Significantly higher root length (12.5 cm), root volume (16.4 cc), root dry weight (8.3 g.plant-1) nutrient uptake (12.2, 2.3, 23.6 kg.ha-1 N, P, K) and yield (659 kg.ha-1) were recorded for seed pelleting. Influence of foliar nutrition on root characters was not significant but was significant with regard to nutrient uptake and yield. Combined nutrient formulation sprayed at 30 and 45 DAS recorded higher nutrient uptake (14.8, 2.8, 28.6 kg.ha-1 N, P, K) and seed yield (719 kg.ha-1) in sesame.
