Abstract
The aim of the present investigation was to improving and maximizing the crop water productivity "CWP" and looking for the optimum Scenario of the crop pattern to achieve more crops per drop concept under different agro-climatic zones in Egypt. Therefore, different scenarios of cropping patterns (33 scenarios) were suggested to examine them. The results could be summarized in the following:-
- In Nile Delta region the highest CWP (9.99 kg m-3 water consumption year-1) was obtained for the scenario of tomato (w) + potato (s). Nevertheless, the lowest scenario was registered for barley + soybean (1.21 kg m-3 water consumption year-1).
- In Middle Egypt, the highest scenario gave maximum CWP was found for tomato (w) + potato (s) followed by potato (w) + tomato (s) then sugarcane. On the contrary, the lowest one was registered for barley + sunflower.
- In the same direction, in Upper Egypt CWP ranged from 9.63 kg m-3 water consumption year-1 with the scenario of tomato (w) + potato (s) to 0.78 kg m-3 water consumption year-1 with the scenario of barley + soybean.
- Results clearly showed that the cropping pattern at the three main agro- climatic zones in Egypt which include vegetables crops were superior greatly in crop water productivity.
- The obtained results indicated that the values of "CWP" ranged between 9.99 to 1.21 in Delta, 7.91 to 0.85 in Middle Egypt and 9.63 to 0.78 kg m-3 in Upper Egypt.
