| Abstract | ||||
| The issue of developing and preserving water resources and maximizing their use is one of the most important challenges facing economic development in general and agricultural development in particular. The problem of the study is that in North Sinai Governorate, the relative importance of arable and untapped lands is high, and these lands necessitate For its cultivation, drilling of many costly deep and shallow wells that require large financial funds are needed the study aims in general at production planning for field and vegetative plantings, in addition to studying the efficiency of using surface wells in North Sinai farms, in general, the restricted linear programming model achieved during the year in an optimized state. The net return is about L.E. 85.5 million, compared to about L.E. 74.7 million for the actual situation, and the total water needs amounted to about 20.6 million m3, compared to about 19.6 million m3 for the actual situation, and the total water needs during the year amounted to about 424 thousand labor, compared to 381 thousand labor for the actual situation. The restricted linear programming model achieved during the whole of the year in the case of low water needs about L.E. 74.9 million, compared to about L.E. 74.7 million for the actual situation, and the total water needs amounted to about 17.1 million m3, compared to about 19.6 million m3 for the actual situation, and the total employment for the proposed situation amounted to about 385 thousand labor, compared to about 381 for the actual situation. The study recommends the application of the proposed models that contribute to achieving net returns, lower needs, and total employment more than their actual counterpart, which confirms the importance of applying these models in the production planning of field and vegetable crops in North Sinai. | ||||
