| Abstract | ||||
| IMPACTS of climate change on crop yield losses and increasing in water demand show that Egypt is vulnerable to climate change because of it’s depending on the Nile River basically. The greatchallenge of enhancing the agriculture is increasing the water use efficiency. A field trial was designed in Complete Randomize Block Design and carried out in Saline Soil at Sahl El-Tina (North Sinia) during the two winter seasons 2011/2012 and 2012/ 2013, to study the response of faba bean yield and seed quality to differential water regimes. The experiment included three water irrigation schedules 3600, 6000 and 7200 m3/ha from El-Salam Canal and two varieties of faba bean (Nobaria-1 and Sakha-3). The results indicate the decline in soil salinity values with increasing the water supply regimes. Applying the water regime 7200 m3/ha results in decreasing the soil salinity with 30% compared to the water regime 3600 m3/ha in both seasons. Nevertheless, the results show that weight of seeds/plant (g) and plant height (cm) decreased with reducing of the water supply. Seed quality, high protein, carbohydrate percent, radical length and seedling dry weight were accompanying with low water application (3600 m3/ha). Water use efficiency was convenient with lower water supplies. Using the water regime of 6000 m3/ha with Sakha-3 under saline soil conditions was more efficient according to the concept of water saving, water use efficiency, seed quality and yield. | ||||
