An experiment was conducted at Agronomy Laboratory of AMK Campus Mardan, The University of Agriculture Peshawar during kharif 2017 to investigate the influence of seeds priming of salicylic acid on sesame germination and early growth. The experiment was comprised on seed priming with different level of salicylic acid solutions (0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8% and 0.9%). Ten seeds of sesame local black was sown in each petri dish. Seed priming with 0.9%, 0.8% and 0.7% of salicylic acid solutions took less days to germination (7.6) while dry seeds took more days to germination (12.5). Germination percentage was noted maximum (72.3 %) in 0.9% and 0.8% of salicylic acid solutions. Mean germination time was noted higher (1.07) where seeds were not treated to salicylic acid solutions. The taller seedling (8.4 cm) was recorded in 0.9%, 0.8% and 0.6% of salicylic acid solutions. Shoot weight of (0.67 mg plant-1) was found maximum in 0.9% and 0.7% of salicylic acid solutions, similarly root weight (0.38 mg plant-1) was higher in 0.9% of salicylic acid solutions. On the base of consequences it was determined that levels of salicylic acid 0.6% to 0.9% seed priming performed well for rapid germination and vigorously growth and hence it is recommended under agro-climatic condition of Mardan.
