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 booting to milk stage reduced grain yield by 13.4%.
- 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.
