The present investigation was carried out during rabi season of 2010-11 at Main Castor and Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Gujarat to study the chemical based management of heat stress in mustard. The foliar spray of chemicals was applied at 60 DAS and 75 DAS. Results revealed that foliar application of 75 ppm salicylic acid with first date of sowing 20th October, 2010 when compared with the control were found superior for plant height (183 cm), number of primary branches per plant (4.38), number of secondary branches per plant (10.25), number of siliqua per plant (403), length of siliqua (5.98 cm), number ofseed per plant siliqua (12.63), biological yield (70), harvest index (19.58%), seed yield (13.71g) and oil content (39.65%).
