The main plot treatments comprised three sowings, viz. 22 ºC, 20 ºC and 18 ºC and subplots consisted of eight treatments of bio-regulators, viz. control, water spray, SA @ 100 ppm, SA @ 200 ppm, TSA @ 100 ppm, TSA @ 200 ppm, TGA @ 100 ppm and TGA @ 200 ppm. Crop sown at 20 ºC resulted in significantly highest yield and nutrient content over 22 ºC and 18 ºC. Among bioregulators, an application of salicylic acid @ 200 ppm registered significantly highest yield and nutrient content in grain and straw of wheat, thus, hold a great promise in wheat production under heat stress. |
