| Abstract | ||
| The study aimed at recognizing the most important economic effects of using irrigation with different saline water (mixed water and fresh water) on the productivity of wheat and corn crops in Fayoum Governorate. The study depended on stratified sample data (120) farmers from Itsa District, Fayoum. The economical, quantative and qualitative analysis were used. The obtained results were found to be as the following: 1- The variable costs of wheat crop reduced with mixed irrigation water (706.7 L.E./feddan), compared to that irrigation with fresh water (797.5 L.E./feddan), and for the corn crop, they reduced to 653.1 L.E./feddan with the mixed water compared to the fresh water use (826.1 L.E./feddan). 2- The production function model results for wheat crop revealed the positive effect of seeds (x7) and animal work (x4), and the negative effect of irrigation time (x2), in addition to there was no effect of water type. 3- For the corn crop, the obtained results clarified the positive effect of nitrogen fertilizer (x8), although it used in the first stage of the low of diminishing returns. Also, there was no effect of irrigation water type on the corn crop productivity, although its sensitivity to salinity. 4- The costs economical analysis results for wheat crop showed that the optimum size to maximize profit was; 25.95 ardeb/feddan and 26.82 ardeb/feddan for irrigation with fresh water and mixed water, respectively. Whileas, the optimum size to maximize the cost was found to be; 24.04 and 25.35 ardeb/feddan for irrigation with fresh and mixed water, respectively. 5- The obtained results indicated that the optimum size to maximize of production to maximize production for corn crop was; 18.74 and 23.92 ardeb/feddan which was achieved for 60% and 15% of the farmers in the study for irrigation with fresh and mixed water, respectively. However, the optimum size to maximize of production to maximize production of costs was; 16.74 and 17.91 ardeb/feddan which was achieved by 84% and 43% farmers in the study, respectively. 6- The study recommended that the proper and correct method must be followed and mix the drainage water with fresh water with a ratio of 1:1, in addition to conducting more researches and investigations for treatments of polluted drainage water and use the agricultural extension to guide the farmers. | ||
