Abstract:
Mustard [Brassica juncea (L.) Czern & Coss], belongs to the plant family Brassiceae (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 [20th October (timely sowing), 5th November (Heat stress) and one varietiy (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 Germination (%) of 69.76 and 69.61 was noted for first year when crop was shown on first date of sowing. Significantly less Germination (%) of 69.33 in first year and 69.29 in second years was associated with both date of planting. Maximum Germination (%) of 72.52 and 71.12 for first and second years respectively was noted with treatment T5. The maximum Vigour Index – I of 1402.69 and 1419.80 was noted for both respective years when crop was shown on different date of sowing. Maximum vigor Index – I of 1562.09 and 1580.15 for first and second years respectively was noted with treatment T5. The maximum vigor Index – II of 3.27 and 4.20 was noted for both respective years when crop was shown on first date of sowing in first year and second date of showing in second year. Maximum vigor Index – II of 3.5 and 4.65 for first and second years respectively was noted with treatment T6.
