Abstract
A field experiment was conducted at the Research Station of State Board for Agricultural Research in Abu- Ghraib during the fall season of 2008 and 2009 to study the response of maize to irrigation frequency, planting depth and planting methods. The layout of the experiment was a split-plot in RCBD with four replications. The results showed that irrigation every five days gave high value of ears number per plant 1.27 number seeds per ear 601.0 and 546.6 , weight of seeds per ear 282.8 and 279.1 mg.ear-1 at both seasons, therefore it gave highest grain yield 13.723 and 12.237 ton.ha-1 respectively. Treatment rows then furrowing high value most character, as number of seeds per ear 500.6 and 563.6 at both seasons so it gave superior grain yield at both seasons 10.922 and 9.612 respectively. Treatment of planting depth 16cm gave highest grain yield 12.275 and 10.343 ton.ha-1 respectively at both seasons, among other treatments of planting depth. Treatment of irrigation every five days with rows the furrowing gave high value of grain yield were 14.622 and 12.690 ton.ha-1 respectively at both seasons. Treatment of rows the furrowing with planting depth 16 cm gave superior grain yield were 13.807 and 10.988 ton.ha-1 respectively at both seasons. Treatment of irrigation every 5 days with row the furrowing and planting depth 16 cm gave high grain yield at first season 18.154 ton.ha-1 and 14.390 ton.ha-1 at second season.
