Influence of Seed Treatment and Antioxidant Spray on Crop Growth, Seed Yield and Quality in White Cowpea Vigna unguiculata (L.) Walp cv. IT - 38956 - 1

摘要

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 and seed yield in white cowpea. The seed treatment with micronutrient like FeS0_41 per cent, CaCl_21 per cent, Sulphur 1 per cent and antioxidant spray viz., salicylic acid, ascorbic 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 (FeS0_4 1 % + CaCl_21 % + Sulphur 1 %) and foliar spray of (salicylic acid @ 100 ppm + ascorbic acid @100 ppm) has registered higher crop growth and seed yield viz., plant height at 30 DAS (15.41 cm), 60 DAS (27.76 cm) and at harvest (35.06 cm), number of leaves plant1 at 60 DAS (19.20), number of branches plant1 at 60 DAS (11.07) and at harvest (12.15), numbers of effective nodules at 60 DAS (16.68), seed size (5.86 cm~3), number of pods plant'1 (10.47), no of pods cluster1 (3.27), pod length (14.86 cm), number of seeds pod1 (10.00), seed yield plot~(-1) (0.83 kg), seed germination (92.50 %), test weight (151.90 g), mean seedling length (38.42 cm), mean seedling dry weight (52.83 mg), SVI-I (3553), SVI-II (4252), TDH (4.00 A_(480) nm) and lower electrical conductivity (515.70 muS cm~(-1)) compared to control and other treatments.
