Abstract AR

The research aims in general to study the efficiency of using surface wells in North Sinai farms, and the most important water factors affecting the production of the most important plant crops under the drip irrigation system.

The research was mainly based on primary data through a field questionnaire for a stratified random sample of surface wells consisting of 112 wells based on the relative importance of surface wells.

A stratified random sample was selected from 95 farms producing vegetable and fruit crops with a drip irrigation system during 2020 production season.

He indicated that the number of wells in the North Sinai governorate reached about 2, 198 wells, of which private wells contribute about 93.2% during 2019.

As for the geographical distribution of the surface wells in the private sector, the results indicated that: Al-Arish center occupies the first place among the governorate, with relative importance It is about 45.3% , while Al-Hasana Center occupies the last place by about 4.6% during 2019.

With regard to the results of the statistical measurement of the effect of water factors of the quantity of production of plant farms under the drip irrigation system, the results showed that the most influential water factors are the amount of irrigation water per thousand cubic meters in the season, the number of irrigation hours per day, the number of irrigation times per year and finally the salinity of the irrigation water per thousand parts per million.
