Abstract

Terminal heat stress poses a significant threat to chickpea (Cicer arietinum L.) production, particularly as climate change increases the frequency and intensity of high-temperature events. This stress adversely affects crop growth, physiological processes, and ultimately yield, necessitating the development of effective mitigation strategies. Therefore, this study was conducted with the objective of assessing how different sowing dates and foliar applications of stress protectants, specifically salicylic acid, potassium nitrate, and thiourea, affect the chickpea performance under terminal heat stress conditions. The study was carried out at the Punjab Agricultural University, Ludhiana, India, during Rabi (winter) season of 2021 − 22 and 2022 − 23. Results indicated that early sowing of chickpea, that is 1st November significantly improved plant height, dry matter accumulation, symbiotic parameters, yield attributes, yield, and nutrient uptake compared to later sowing dates of 20th November and 10th December. Additionally, the application of stress protectants, that is salicylic acid at 100 parts per million (ppm), thiourea at 1000 ppm, and potassium nitrate at 2%, significantly enhanced the crop’s resilience to heat stress, leading to improved growth, symbiotic parameters, yield, and nutrient uptake compared to water spray and no spray. These findings underscore the importance of timely sowing and the application of stress management strategies to optimize chickpea productivity amid increasing terminal heat stress under the changing climatic scenario.
