The experiment was designed to study on the effect of salicylic acid as a foliar spray on the growth, yield and fruit quality of sweet pepper (Capsicum annum L.) in the net house of Sher-e Bangla Agricultural University, Dhaka, Bangladesh and the treatments included @ 0 (control), 0.3, 0.6, 0.9, 1.2, 1.5 and 1.8 mM of salicylic acid. The single factor experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The vegetative growth, fruit yield and quality of sweet pepper were found positive by the application of salicylic acid. Spraying 1.8 mM salicylic acid showed the highest plant height, branches plant-1 and stem diameter; fruit number, weight, length and diameter; vitamin C content and total soluble solid content and also increased the fruit yield compare to control. Therefore, salicylic acid represents the potentiality to enhance fruit yield and quality of sweet pepper.
