Studies on the inter-relationship among irrigation and maize varieties on yield and water relations using some statistical procedures

Khalil, Fouad A. | Muhammad, Samya G.
Two field experiments were carried out in 2004/2005 to evaluate the effect of four irrigation intervals (irrigation every seven days, irrigation every seven days until silking then irrigation every two weeks, irrigation every two weeks until silking and irrigation every seven days and irrigation every two weeks during the whole season) and two maize hybrids (TWC 310 and TWC 324) on maize yield, its components and some water relations to determine the most important yield components using different statistical procedures. Results showed that irrigation intervals, differed significantly with respect to ear diameter, number of grains/row, number of grains/ear and biological yield (ton/fed.) in the first season. In the second season irrigation intervals were found to be significant for ear length, ear diameter, number of barren/plant, plant yield, grain yield (ardab/fed.) and biological yield (ton/fed.). Results also indicated that both hybrids were not significantly different, except for number of grains/ear in the first season and biological yield in the second season. The interaction between hybrids and irrigation treatments revealed that, to obtain the highest maize yield, yield components and water use efficiency, it could be recommended to plant TWC 310 and irrigate it every seven days. Furthermore, simple correlation analysis revealed that seven yield components were found to be highly significant and correlated with plant yield.
