Abstract
A field experiment was conducted on clay loam soil having medium in available nitrogen and phosphorus and high in available potassium with slightly alkaline in reaction at the Agronomy farm, Rajasthan College of Agriculture, MPUAT, Udaipur during two consecutive rabi seasons of 2021-22 and 2022-23 with the objective to evaluate the response of wheat crop to agro-chemicals for mitigating heat and water stress in wheat under varying thermal regimes. The experiment comprised of two thermal regimes, three water stress treatments and four agro-chemicals thereby involving 24 treatment combinations which were replicated three times in split plot design. The wheat crop sowing at 20±1 ºC significantly enhanced plant height. No water stress as compared to water stress (flowering and milking stage), and foliar application of chitosan (50 ppm) both proved significantly superior in plant height.
