Targets this research study of the effect of using modern irrigation systems on revenues and the cost of producing feddans of winter and summer crops in the research sample in the new lands in Beheira governorate, the study of the impact of using modern irrigation systems on feddan productivity and the use of irrigation water and the inputs of quantitative production of winter and summer crops in the research sample.

In new lands, finally, measure the impact of technological change in different irrigation systems on the productivity of winter and summer season crops in the new lands in Beheira, depending on the cross-sectional data in a cluster sample random multi-stage light size was 571 observations of winter crops are divided as follows: (135, 59, 65) observations crop (wheat, potatoes, tomatoes) respectively for the users of inundation irrigation system, (134, 57) observations for the crop (wheat, potatoes) respectively for the users of sprinkler irrigation system, (57, 64) observations crop (potatoes, tomatoes) respectively for users of drip irrigation system, for crops summer season amounted to 531 sample size watch divided into (81, 75, 64) observations crop (maize, potatoes, tomatoes) respectively for the users of inundation irrigation, (78, 55) observations crop (maize, potatoes) respectively for users of sprinkler irrigation system, (78, 55, 63) observations crop (maize, potatoes, tomatoes) respectively for the users of the drip irrigation system.

In order to study the economic impact of the use of different irrigation systems in winter crop production (wheat, potatoes, tomatoes) and summer crops (maize, potatoes, tomatoes) represented the research sample of new lands in Beheira governorate, a drip irrigation system came in the first place and the system of sprinkler irrigation in second place, In terms of achieving the product rationalization in cost items and consumption of irrigation water and increase (productivity per feddan, total revenue, net yield per feddan), which resulted in an increase in the net water unit yield of the research sample crops compared to the irrigation system inundation.

The results of the analysis of changes in the productivity of the total factors of the production of winter and summer season crops Represented by the research sample in the new land in the governorate of Beheira, that drip irrigation system ranked first and sprinkler irrigation took second place in terms of positive changes in the productivity of total factors and the rate of technological growth when compared inundation irrigation system.

It is inferred from the above that modern irrigation systems (drip, sprinkler) in the new lands in the governorate of Beheira brought the expected results by rationalizing the items of total costs and water consumption, and brought about positive changes in the productivity of the total factors and the technological growth rate of the productivity of winter and summer crops represented by the research sample when compared to the system of irrigation inundation, Therefore, we recommend decision makers to work hard to expand the use of modern irrigation systems in the new and old lands in Beheira Governorate, which has positive results on increasing productivity and net yield per feddan and net water unit revenue and rationalization in (total costs, consumption Irrigation Water).
