Abstract
An experiment was conducted at Department of Seed Science and Technology, UAS, GKVK, Bengaluru during kharif-2017 to study the influence of seed treatment and antioxidant spray on crop growth, seed yield and quality in white cowpea. The seed treatment with micronutrient like FeSO4 1 %, CaCl2 1 %, S 1 % and antioxidant spray viz., ascorbic acid, salicylic acid @ 100 ppm and @ 150 ppm with their combinations with a control includes 15 treatments replicated three times under RCBD. The results revealed that seed treatment with (FeSO4 1 % + CaCl2 1 % + S 1 %) and foliar spray of (salicylic acid @ 100 ppm + ascorbic acid @ 100 ppm) has registered higher crop growth, seed yield, quality and nutritional constituents attributes viz., plant height at 30 DAS (15.41 cm), 60 DAS (27.76 cm) and at harvest (35.06 cm), number of leaves plant-1 at 60 DAS (19.20), number of branches plant-1 at 60 DAS (11.07) and at harvest (12.15), numbers of effective nodules at 60 DAS (16.68), seed size (5.86 cm3), no of pods plant-1 (10.47), no of pods cluster-1 (3.27), pod length (14.86 cm), number of seeds pod-1 (10.00) and seed yield plot-1 (0.83 kg), seed germination (92.50 %), field emergence (86.67 %), mean seedling length (38.42 cm), SVI-I (3553), TDH (4.00 A480 nm), lower EC (515.70 μS cm-1), TSP (23.76 %), iron (63.52 mg kg-1), calcium (0.50 %) and sulphur (0.30 %) compared to control and other treatments.
