| Abstract | ||
| Three irrigation water regimes for wheat cv Bro bread, viz. 100%, 80% and 60% ETc were used over three successive seasons (2009/10, 2010/11 and 2011/12) at the Agricultural and Veterinary Research Station of King Faisal University using a randomized complete block design with three replicates. Data were collected on different parameters pertaining to crop agronomic and yield attributes viz. plant population and height, number of tillers, leaf area index (LAI), number of spikelets and grains/spike, 1000-grains weight, harvest index (HI) and total grain yield; as well as water use efficiency (WUE). Obtained results revealed that, watering regime of 60% ETc was statistically (P £ 0.05) inferior in terms of almost all the prescribed parameters. 100% and 80% ETc watering regimes were statistically similar in comparison to their corresponding treatments in all seasons. In addition, the obtained results showed that averaged of watering regime viz. 100, 80 and 60% ETc were 2.90, 2.73 and 2.03 t/ha, respectively. WUE was recorded the highest values (0.42) at 80% ETc watering regime, whereas the lowest (0.36) at 100% ETc. | ||
