Optimal cropping pattern is a relative concept because it is not easy to know exactly what is ideal and the phenomenon of grappling with targets.

There are many suggestions that can be made to improve the Cropping pattern composition, with the objectives to be achieved or the specific production resources.

The optimum cropping pattern is the one that maximizes the economic return under the various possibilities available and other determinants.

The cropping pattern expresses the relative distribution of different crops on the agricultural plot for one year.

It is defined as the system of distribution of agricultural land available on plant plantations that rotates in agricultural land and occupies it for one agricultural year.

The optimal Cropping pattern which achieves the following: 1.

The Cropping pattern, which achieves self-sufficiency of food crops, which meets the needs of the population of this governorate.2.

The Cropping pattern, which maximizes the net yield of the landfill in light of the limited agricultural land and the amount of water used and labor available.3.

The Cropping pattern that minimizes water needs in light of limited agricultural resources.4.

Crop composition, which maximizes the net return of the unit of irrigation under limited agricultural resourcesThe results of the analysis of the linear programming models of The Cropping pattern proposed by the prevailing crop structure as an average for the period (2012-2016)Cultivated area: The results of the analysis of the cropping patterns proposed in accordance with the different objectives of the target showed that the highest agricultural intensification rate achieved by the first model was an average model of average net yield per feddan through the crop area which reached about 14.843 million feddans.

Total Revenue: As for the total yield of the cropping structure, the first model achieved the highest yield compared to the yield obtained from the actual crop structure, which amounted to about 128.4 thousand pounds, compared to 122.6 thousand pounds return from the actual crop structure.

Quantity of irrigation water used: The second model used the lowest quantity of irrigation water, which was about 73.1 thousand cubic meters compared to the quantity consumed in the actual crop structure, which is about 77.9 thousand cubic meters.

Return of used irrigation water unit: The results of the model analysis show that the second model achieved the highest economic return of the unit of irrigation, where the cubic meter of water achieved a return of 59.57 pounds / cubic meter of water, an increase of 7.20 pounds / cubic meter of water compared to the yield of the unit used in the actual crop structure
