e0“Elongating the interval of irrigation from 7 to 14 days at any of the three growth stages resulted in significant reductions estimated by 19.6, 13.4 and 9.8%, respectively”
e1“from planting to booting, from booting to milk stage and from milk stage to maturity”
e2“bread wheat (Triticum aestivum, L.)”
e3“irrigation every seven days through the season resulted in the highest grain yield from all tested genotypes”

Other claims from this paper (18)
- Intervention effect Seven-day irrigation throughout the season gave the highest grain yield across genotypes.
- Intervention effect Extending irrigation from seven to fourteen days during planting to booting reduced grain yield by 19.6%.
- Intervention effect Extending irrigation during milk stage to maturity reduced grain yield by 9.8%.
- Intervention effect Longer irrigation intervals depressed spikes per area, kernels per spike and thousand-kernel weight, especially early in growth.
- Intervention effect Each successive nitrogen level significantly increased grain yield and yield components.
- Association Grain yield differed significantly among genotypes.
- Observation Gemmeiza 5 had the highest grain yield at 5.81 t/ha, statistically indistinguishable from Sakha 93.
- Observation Sakha 69 had the lowest grain yield at 4.61 t/ha.
- Association The treatment interactions were significant.
- Observation Highest yields occurred for Gemmeiza 5 and Sids 1 with seven-day irrigation and 216 kgN/ha fertilizer.
- Association Genotypes differed substantially in response to increasing nitrogen fertilizer.
- Observation Grain yield response index was highest for Gemmeiza 5 and lowest for Sakha69.
- Intervention effect Grain yield response index and water-use efficiency were highest with seven-day irrigation at the first two stages and declined with longer intervals.
- Intervention effect Increasing nitrogen significantly increased water-use efficiency.
- Association Water-use efficiency varied significantly among genotypes and was highest in high-yielding genotypes.
- Recommendation The authors recommend Gemmeiza 5, Sakha 93, Giza168 and Sids 1 for reclaimed sandy soil in El-Bustan.
- Recommendation For maximum yield, the authors recommend seven-day irrigation.
- Recommendation For maximum yield, the authors recommend nitrogen at 216 kgN/ha.
