ECONOMIC EVALUATION FOR THE EFFECT OF IRRIGATION RATES ON SOME BREAD WHEAT GENOTYPES

The wheat crop is considered one of the main grain crops and one of the most important strategic crops in the Egyptian diet. The study aimed to evaluate the effect of irrigation rates on some wheat genotypes using data of a field experiment conducted in the Agricultural Research Station of Itay AlBaroud, Beheira Governorate during 2016/2017-2017/2018 seasons. Three irrigation rates (2, 3 and 4 irrigations after planting) were applied to six wheat genotypes (Egypt 2, Gemmiza 11, Egypt 1, Shandaweal 1, strain 1, strain 2). By studying the statistical relationship between the area, in thousand feddans, and time factor, it was shown that the area significantly increased annually by 52.84 thousand feddans. Also, the productivity increased by 0.04 ardab/fed and this increase was not significant. meanwhile, the total production significantly increased annually by 1094.14 thousand ardb. This increase was due to the increase in the cultivated area. The results indicated that the increase in the farm price, productivity costs, total revenue, net revenue per feddan is estimated at 26.97 pound/fed, 240,48 pound/fed, 611.26 pound/fed, 370.79 pounds/fed, respectively. It was also found that the return of the invested pound is considered an economic gain for the farmer during the period (2002-2017). The results revealed that the second irrigation treatment (3 irrigations after planting) achieved the highest feddan productivity, highest revenue, highest net return and highest value of the invested pound. Moreover, the wheat cultivar Egypt 1 gave the highest productivity, highest revenue, the highest net return and highest return of the invested pound in the first season, while strain 1 achieved the highest productivity, the highest revenue, the highest net return and the highest return of the invested pound in the second season.
