Abstract :

        To study the effect of water stress and the application of growth regulator (cycocel ) and Zinc spray on the protein rate, the major elements and some physical characteristics in corn (hybrid Ns540) .A split-split plot experimental with three replications in a randomized complete block design in Semnan Agricultural Research Station in 2010 in was run. The main factor included three levels of irrigation (irrigation complete, disconnect the water at 71 BBCH and 61 BBCH) in main plots and taking cycocel three levels (without taking cycocel consumption cycocel 1500, and 3000 parts per million) in the subplots and spraying zinc sulfate in three levels (no foliar applications, foliar applications of zinc sulfate at 3 and 5kg per thousands) as the subplots - are considered minor. Analysis of variance showed that the impact of cut irrigation on protein content, major elements such as phosphorus, potash, zinc, copper and iron, and water use efficiency is significantly. With the increased tension of the grain protein content and concentration of phosphorus, potash, zinc, iron and copper were reduced and increased water use efficiency. That results showed, taking cycocel, potash and phosphor decreased and other indicators increased. Zinc  spraying the exception of the iron (Fe) increase in other indicators. the Correlation between Important elements and components of protein content and water use efficiency showed that Positive and significant correlation between water use efficiency and a high copper content of 0.474 percent is established And grain protein correlated with leaf phosphorus content of 0.522 percent. The findings can be to corn-growing of Semnan and similar region drought conditions that prohibit the use of certain materials and components that manufacturers offer to achieve good economic performance and quality.
