| Abstract | ||||
| This study aimed to design alternative cropping patterns for the actual cropping pattern to maximize the total net return of water unit in different agro- ecological zones in Egypt. Egypt was divided into five different agro- ecological zones, for exploiting the points of differentiation for each zone, and providing the designers of agricultural policy with an opportunity to guide them adjusting the path of agricultural production, therefore satisfying the greatest needs of the Egyptian society from agricultural crops under the limited agricultural resources, through maximizing the economic use of these resources using linear programing approach. The total net income for the alternative cropping pattern at the first ecological zone increased by L.E. 1.25 billion, which represented 1.06% from Egyptian vegetables production in the year 2010, that alternative saved about 779 million m3 from the actual irrigation water, it’s represented 3.52% from available total irrigation water, which could be used to irrigate 232.93 thousand feddan in new land at the same zone, and hereby the total net income will be increased by L.E. 753.3 million. Therefore the total net income for the alternative cropping pattern at the second ecological zone increased by L.E. 365.1 million, that alternative saved about 297.2 million m3 from the actual irrigation water, it’s represented 4.8% from available total irrigation water, which could be used to irrigate 93 thousand feddan in new land at the same zone, and hereby the total net income will be increased by L.E. 275 million.Whereas the total net income for the alternative cropping pattern at the third ecological zone increased by L.E. 291.5 million, that alternative saved about 31 million m3 from the actual irrigation water, it’s represented 0.6% from available total irrigation water, which could be used to irrigate 5.5 thousand feddan in new land at the same zone, and hereby the total net income will be increasedby L.E. 19.7 million. The total net income for actual cropping pattern in the forth agro- ecological zone was reached L.E. 5.77 billion, while the total net income for alternative pattern was reached L.E. 6.07 billion. L.E. 301 million was difference between the estimated income for actual pattern and alternative pattern. The total net income for actual cropping pattern at the last agro- ecological zone was reached L.E. 2.38 billion, while the total net income for alternative pattern was reached L.E. 2.54 billion. L.E. 162 million was difference between the estimated income for actual pattern and alternative pattern. It is represents about 8.6% of the total value of vegetable production in 2010. | ||||
