Abstract:
Mustard [Brassica juncea (L.) Czern & Coss], belongs to the plant family Brassicaceae (Cruciferae) or the mustard family. In India, B. juncea is a predominant species, which accounts for nearly 80% of the production area of the oilseed. The present investigation entitled “Effect of dates of sowing and chemicals spray to mitigate the effect of increasing temperature on seed set, yield and quality of Indian mustard [Brassica juncea (L.) Czern and Coss]” field experiment was carried out at Oilseeds Farm, Kalyanpur, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during rabi season 2015-16 & 2016-17. The experiment consisted of two sowing dates [20^th October (timely sowing), 5^th November (Heat stress) and one variety (Mustard “Rohini”) with seven treatments likewise Control (T₀), Glycine Betaine - 600 ppm (T₁), Salicylic acid – 800 ppm (T₂), Salicylic acid- 400 ppm (T₃), Ascorbic acid- 10 ppm + Citric acid 1.3% (T₄) Alfa Tocopherol-150 ppm (T₅) KCL - 1% (T₆) there by making forty two treatment combinations. The maximum Number of Primary Branches 5.12 and 5.36 were noted for both respective years when crop were shown on first date of sowing. Maximum Number of Primary Branches 5.63 and 6.11 for first and second years respectively were noted with treatment T₂. The maximum Number of Secondary Branches of 16.78 and 16.37 were noted for both respective years when crop were shown on first date of sowing. Maximum Number of Secondary Branches 19.26 and 18.53 for first and second years respectively were noted with treatment T₂. The maximum days to 50% flowering of 67.95 and 68.55 were noted for both respective years when crop were shown on first date of sowing. Maximum days to 50% flowering of 65.33 and 65.50 for first and second years respectively were noted with treatment T₅.
