Salicylic acid increase resistance in plants to overcome both biotic and abiotic stresses. Therefore a study was conducted to investigate the effect of drought and foliar application of salicylic acid on growth and development of Gladiolus grandiflorus L at University of Swabi, Khyber Pakhtunkhwa, Pakistan during spring 2019. Two factorial Completely Randomized Design (CRD) was used having three replications. Salicylic acid with levels (0, 40, 80 and 120 ppm) and drought with intensities (no stress, mild stress and severe stress of field capacity water volume) were tried on gladiolus crop. Drought was induced to main plots whereas; salicylic acid was applied to plants in subplots. Bulbs were sown in pots having dimensions 230 × 240 × 240 mm in a polytunnel and then normal practices were carried out for 45 days from plantation date. After that, control pots were irrigated with 3 days, mild stress with 6 days and severe stress with 9 days interval. Salicylic acid was prayed on 30th, 45th and 60th day after planting. Results disclosed that salicylic and droughts have significantly affect gladiolus growing attributes while their interaction was significant for plant height, leaf length and spike length. Maximum plant height, rachis length, number of leaves plant-1, leaf length, leaf area, spike length, number of florets plant-1, flower diameter and spike diameter were recorded in control plants as compared to mild and severe stressed plants. All the selected parameters recorded maximum results when plants were treated with 120 ppm of salicylic acid. It can be concluded that foliar application of salicylic acid at 120 ppm concentration should be sprayed during dry spell of gladiolus growth period
