The field experiment was carried out at Scheme for Research on Onion Storage, Department of Horticulture, Mahatma Phule krishi Vidyapeeth, Rahuri during the rabi season of 2015-16 to study the effect of salicylic acid on onion (Allium cepa L.) cv. N-2-4-1. The experiment was laid out in a Factorial Randomized block design with two replications consisting two factors, Factor-A (03) with levels of concentration and water spray and Factor-B (07) with seven levels of time of applications. The result indicated that, there was significant influence of foliar application of salicylic acid on growth parameters viz., plant height (68.28-76.45 cm), number of leaves per plant (13.15-15.30), neck thickness (0.84-1.07) and higher level of chlorophyll content (0.58-0.75 mg 100 g-1 f.w) as compare to water spray. The foliar application of salicylic acid at lower concentration (100 mg/l) gives significantly maximum plant height, number of leaves per plant, total chlorophyll content, bulb diameter, average weight of bulb, total bulb yield, marketable bulb yield as compare to higher dose (150 mg/l) and water spray. Three foliar sprays at 30, 45 and 60 DAT were beneficial for vegetative growth, yield, quality and storability of onion cv. N 2-4-1 than either single or two sprays of salicylic acid.
