Abstract

Plant growth promoting substances (PGPS) improve plant performance through modulation of its growth and yield. To study the possible role of PGPS maize was subjected to various PGPS Viz; kinetin (30 ppm), humic acid (2%), 'Moringa' leaves extract (MLE) (2%), ascorbic acid (2%), Salicylic acid (2%), 'neem' seed powder (NSP) extract (2%) and water spray (control) at 6 leave and 8 leave stage. We found that foliar application of kinetin, humic acid, MLE and ascorbic acid remarkably (p<=0.05) improved growth, yield and quality attributes of maize while salicylic acid and NSP extract application was not so much promotive in action compared to control (water spray). MLE enhanced crop growth rate and number of leaves per plant while maximum leaf area, 1000-grain weight, grain and biological yield as well as grain protein and starch contents were recoded where ascorbic acid was applied. However, plant height and total phenolic content were highest in plants treated with humic acid. So, all tested PGPS were variable in their effect, however, they improved the plant performance and may be applied to improve growth and yield of maize.
