Abstract: A field experiment was conducted at Agronomy Farm, SKN College of agriculture, Jobner, Jaipur, Rajasthan to evaluate the effect of sowing time, varieties and salicylic acid (SA) application on the yield of Wheat. The experiment was carried out in split plot design and replicated thrice The experiment consisted of two date of sowing 20th November (timely sowing) and 20th December (late sowing) with two varieties Raj-4079 & Raj-4120 and four levels of salicylic acid (Control, SA 50 ppm, SA 100 ppm and SA 150 ppm). Salicylic acid was sprayed at two stages i.e. at first 50 DAS stage and at second 80 DAS. Under this experiment determine the effect of high temperature and SA on various yield parameters like Plant height(cm), number of effective tillers-1, grain yield per plant, test weight, seed, straw, biological yield and harvest index (HI) and this parameters were recorded at harvesting and after harvesting. Results were revealed that yield parameters viz. Plant height (76.94 cm), effective tillers-1(2.28), grain yield (16.37 g/plant), test weight (41.39 g), seed yield (30.22q/ha), straw yield(51.22q/ha), biological yield(81.44q/ha) and harvest index (39.55%) were higher in timely sowing compare to late sowing. In case of varieties all yield parameters found superior in Raj-4079 than Raj-4120. The study thus reveals that adverse effect of temperature on yield & yield attributes of wheat varieties may be improved by treatment with SA (150 ppm) under normal as well as late sown conditions. Salicylic acid (SA) 150 ppm concentration of spray treatment mitigates the effect of high temperature on yield and yield attributes traits in wheat genotypes with better result in yield.
