Drought is an important factor-limiting yield in maize. Cytokinins are well reported for reducing the perilous effects of drought stress in maize (Zea mays L.). A net house study was planned to compare the efficacy of synthetic cytokinins, benzyl amino purine (BAP) with a natural source of cytokinins i.e., leaf extract of Moringa olifera as foliar application on maize seedlings subjected to different levels of drought (75% & 50% of field capacity). On weekly basis, the plants were sprayed with BAP (50 mg L-1) and moringa leaf extract (MLE) (30 times diluted with water) @ 25 mL/plant. The Plants applied with normal irrigation (100% field capacity) and water spray were taken as control. The crop was analyzed for seedling vigor, growth, water relations, physiological attributes and enzymatic antioxidants.
