Wheat is staple food of region, as it contributes 60% of daily caloric intake, but its delayed sowing reduces yield due to short life span. Moringa leaf extract (MLE) is considered to improve growth and development of field crops. Study comprised of two experiments. First experiment, freshly extracted MLE and in combination with growth-promoting substances were stored at two temperature regimes. Chemical analysis, after 1, 2, and 3 months’ storage period, showed that phenolics and ascorbic acid concentrations decreased with increasing storage period. Fresh extracts improved speed and spread of emergence and seedling vigor. Effectiveness of MLE in terms of phenolics and ascorbate concentrations was highest up to 1 month which decreased with prolonged storage. Growth enhancing potential of MLE also reduced with increasing storage duration. Under field conditions, the bio-efficacy of these fresh and stored MLE was compared when applied as foliar spray at tillering and booting stages of wheat. Foliar applied fresh MLE was the most effective in improving growth parameters. Fresh MLE enhanced biochemical and yield attributes in late sown wheat. This growth-promoting potential of MLE decreased with storage time. Application of fresh MLE helped to achieve higher economic yield.
