Investigation of changes in corn hybrids grain protein, proline, and micronutrient content under the influence of drought and fertilizers

In order to investigate the effect of drought stress and application chemical biological fertilizers potassium maize cultivars on micronutrient uptake, protein content, proline changes, an experiment was conducted as a split-plot based randomized complete block design with three replications. The main factor levels treatment, irrigation, irrigation cut at 12 leaf stage flowering stage; first subfactor fertilization fertilizer 100%, 70% +30% fertile-2 biofertilizer (60g/h) 50% +50% (100g/h) second related hybrid AS71, NS640, CORDONA. results showed that significantly reduced absorption phosphorus elements increased zinc, copper, iron in seeds. grain content normal highest. Drought content. Also, use amount absorption, Finally, AS71 better than other hybrids terms nutrients, protein,
