Abstract

Heat stress is now widely accepted as an important ecological factor influencing growth of plants and production. Rising temperatures as a result of global warming cause heat stress, reducing plant development and potential output throughout the entire globe. A field experiment was carried out at Chandra Shekhar Azad University of Agriculture & Technology, Kanpur, to minimize the heat stress induced-losses in chickpea plants with the foliar spray of chemicals during two consecutive years 2021-22 and 2022-23 at Rabi season (November-April). Experimental treatments comprise two chickpea varieties (RVG-202 and RVG-203) sown on same day (15th November). foliar spray of seven chemicals at at vegetative, anthesis and at both stages. The chemcials include Salicylic acid @ 800 ppm, Salicylic acid @ 400 ppm, Ascorbic acid @ 10 ppm, Potassium chloride @ 1%, Thiourea @ 400 ppm, Cycocel @ 400 ppm and Control (no spray). Results suggested that heat stress severely reduced the chickpea growth and productivity. However, foliar application of salicylic acid and thiourea positively affected the plant growth attributes which ultimately increased the final productivity. Concisely, the foliar spray of chemicals particularly, salicylic acid and thiourea modulated the heat stress induced losses in chickpea cultivars, RVG-202 and RVG-203 by improving their antioxidant defense mechanism and enhanced the productivity.
