Abstract: Due to the extensive use of intensive cropping systems, especially in north-western India, late mustard planting is quite widespread, which poses an alarming danger to mustard globally. As a result, mustard crop has to face the problem of terminal heat stress. It alters the morpho-anatomical, physiological, and biochemical aspects of plants, affecting their growth and development and lowering their output. Nonetheless, there exist diverse approaches to enhance yield in mustard following anthesis when exposed to elevated temperatures. The study was conducted at the Students Instructional Farm at Acharya Narendra Deva University of Agriculture and Technology during rabi season 2021-22 and 2022-23. The Maya, NDR-8501, and RH-725 varieties of mustard were used in the experiment. Using chemicals that induce heat tolerance, seeds were sown on three separate dates: (D1) sown on October 15, (D2) sown on October 30, and (D3) sown on November 15. At regular intervals, information on various parameters was gathered. The optimum date of sowing for mustard was observed as October 30th in the Ayodhya district of eastern Uttar Pradesh (North India). In the case of heat tolerance inducing chemicals, the higher growth components, seed yield, and contributing traits were recorded when applying salicylic acid (800 ppm), followed by salicylic acid (400 ppm), and the effect between the date of sowing and heat-inducing chemicals was also observed. Due to terminal heat stress, seed yield and its contributing qualities performed poorly since the planting was delayed. Therefore, the seed yield might be changed by using chemicals that cause heat, even postponing sowing until November, and vice versa.
