Study of drought stress correlation on yield and yield components of maize cultivars (Zea mays L.)

This article was investigated to study the correlation and analysis of drought stress regression on maize cultivars' yield components. The variance results showed a significant difference between levels in terms plant height, total dry weight number seeds per row, cob, grain yield, harvest index, stem diameter, cob with protective leave. Also, there ear without leaves, length, weight, 100-seed seed hybrid treatments. There were statistically differences cultivars leaf area, ear, wood, weight. traits for mean positive length 5 pieces wood also bark highest correlation. is area at probability level 0.05. Correlation coefficients non-stress conditions which increase compared conditions. under full that coefficient trait height significant. From conditions, it can be concluded most important components are row. While moisture show row has stage did not any yield.
