Abstract
Drought is one of the main serious problems for agriculture production which its intensity is increasing in many parts of the world. Hence, this experiment was carried out during 2015 and 2016 to study responses of four pomegranate cultivars Manfalouty, Nab-Elgamal, Wonderful and Wardi grown in sandy soil, in North Sinai Research Station, under different irrigation levels 100%, 75% and 50% of the recommended water level (11, 8.25 and 5.5m 3 /tree/year) on growth, flowering, yield and fruit quality. The results obtained that the highest irrigation level 100% (11 m 3 /tree /year) enhanced vegetative growth, fruit set (%), number of fruits/tree, yield/kg/tree and fruit quality (fruit weight, diameter, length,) followed by descending moderate irrigation level 75% (8.25 m 3 /tree /year) while, 50% (5.5 m 3 /tree/year) gave the lowest values during both seasons. One the other hand, the data showed that the percentage of total sugars, acidity and proline significantly increased by decreasing amount of water. Manfalouty cultivar gave the highest values of growth parameters, total flowers/tree, fruit set (%), no of fruits, yield, fruit weight aspects and sugar content, and the lowest fruit drop (%), fruit peel (%), peel thickness (cm) followed by descending order of Nab-Elgamal cultivar. While, Wonderful and Wardi cultivars exhibited the lowest significant values in both seasons respectively. Moreover, data indicated generally that the best treatment combination was gained from using irrigation level at 100% (11 m 3 /tree /year) with Manfalouty and Nab-Elgamal which exhibited the highest values for all vegetative growth parameters, fruit set (%), fruit weight aspects, fruit arils and the least sugar content. Whereas, the maximum flower/tree, number of fruits/tree, fruit retention (%) and yield was observed with Manfalouty under the same irrigation level. On the other hand, Wardi cultivar under least irrigation treatment at 50% (5.5 m 3 /tree/years) recorded the highest significant values of fruit drop (%), fruit peel (%), fruit thickness (cm), proline (%) and acidity (%). Generally, data clarified that Manfalouty and Nab-Elgamal pomegranate cultivars are considered as a highly tolerant and significant to drought stress under North Sinai conditions compared to Wonderful and Wardi cultivars.
