Field experiment was carried out in 2015/ 2016 dry season at the orchard of the Teaching and Research Farm of Bayero University, Kano and National Horticultural Research Institute (NIHORT) Bagauda, progeny orchard Kadawa to study the growth response of sweet pepper to salicylic acid under moisture stress and non stressed conditions. Treatments consists of four rates (0, 0.2, 0.4 and 0.6g/l) of salicylic acid and four moisture stress (no stress, vegetative, flowering and fruit setting) stages. These were laid out in split plot design with three replications. Foliar application of salicylic acid in sweet pepper has significantly influenced all the growth characters measured. The effects however varied among locations with BUK having the best response. Stress stage was also significant in this study, indicating the flowering and the fruiting stages as most critical. Based on this findings hence, exogenous application of salicylic acid could mitigate moisture stress for enhanced growth in sweet pepper. Further work is suggested to justify the rates of SA applied.
