Abstract
Drought is one of the most important abiotic factors acting as a bar in the progress of agriculture around the world. Like other crops, cereals also have to endure the impact of limited water availability. A pot experiment was conducted to check the effects of exogenous application of salicylic acid (SA) on physiological processes of spring maize (DK-6525 and NK- 8711). In this experiment, seed priming, foliar of SA and their combined effects of SA @ 100 mg L-1 were checked at vegetative as well as reproductive growth stages of maize. In this experiment control was no priming and no spray. Then hydro-priming and distilled water spray at vegetative as well as reproductive growth stages was applied to have a better comparison with SA application. Crop was raised till its maturity. Results of physio-chemical attributes showed that foliar application of SA at the vegetative growth stage of maize improved dry matter production per plant by 26% under moisture stress conditions along with the water relations and gas exchange parameters to a significant extent
