Abstract
Salinity is a major agricultural problem that adversely affects maize yield. Maize is a major fodder crop which necessitates the improvement of its vegetative performance under salt stress using different doses of moringa leaf extract (MLE). With the objective to tolerate the salt stress, 5 levels of moringa leaf extract concentrations [control, 5%, 10%, 15% & 20%] were foliarly sprayed on maize seedlings raised in saline (70 mM NaCl) and non-saline (0 mM NaCl) hydroponic Hoagland solutions. Plants were harvested 4 wk after applying salt stress and foliage spray of leaf extract. The following morphological characters (shoot length, root length, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight, shoot root ratio) and biochemical parameters (sodium and potassium contents) were evaluated. The experiment was laid out in CRD in factorial arrangement with 5 replicates. The data collected was subjected to statistical analysis at 1% probability level and DMR was used to separate the significant treatment means. The results showed that moringa leaf extract seems to be effective in enhancing the salinity tolerance of maize. The foliar application of moringa leaf extract improved the shoot and root growth significantly. Moringa leaf extract proved to be helpful in reducing the Na and increasing the K content of the leaf. The salinity tolerance of maize was improved as the concentration of Moringa leaf extract was increased up to 15%, but higher concentration (20%) proved to be toxic for maize seedlings.
