Using data envelope analysis to measure the technical and economic efficiency of some elements of the faba bean production in Ismailia governorate

The research aims to estimate the efficiency of the agricultural technical and economic resources used in the production of the faba bean crop in Ismailia Governorate and to determine the optimal combination of productive resources used in production. a questionnaire specially prepared for this purpose, where 100 farms were selected randomly: 30 farms (one feddan or less), 35 farms (greater than one feddan and less than three feddans), and 35 farms (three feddans). It was found that there are 30 farms that achieved full technical competence, where they were distinguished with a constant return on capacity, which means that the actual combination of resources is the same as the optimum, where the capacity efficiency reached one. 65 farms were characterized by an increase in the return on capacity, meaning that these farms could increase the number of resources used and obtain a greater amount of production, while 5 farms were characterized by a decrease in the return on capacity. capacity, which means reducing the resources used in it to achieve full technical efficiency, as it was found that 34 farms consider their farms self-sufficient (self-referential), and 66 farms are considered farms that are a reference for other farms. By estimating the economic efficiency in the case of capacity change, it was found that the farms who achieved economic efficiency were 2 farms with a rate of 7% of the total farmers of the first category, and for the second category, it was found that the farmers who achieved economic efficiency were 2 farms with a rate of 6% of the total farmers of the second category, while the farmers of the third category who achieved economic efficiency were 4 farms with a rate of 11% of the total farmers of the third category, meaning that the first, second, and third category producers can achieve the same level of production at a cost less than the actual costs by 12%, 9%, and 9%, respectively. As it was shown from the estimation of the optimal quantities of resources that achieve economic efficiency in the case of a change in the yield of capacity in relation to the amount of seeds, the quantity of seeds must be reduced by about 5 and 10 kg/feddan for the first and second, respectively, as well as reducing the number of workers by about 2, 6, and 8 workers/feddan for the first, second, and third, respectively, while the amount of nitrogen fertilizer should be increased by about 10 and 5 kg/feddan for the first and second categories, and 5 kg/feddan in the third category. as well as an increase in the amount of phosphate fertilizer by about 50 kg/feddan for the first category; in the third category, regarding the amount of irrigation water, the amount of irrigation water should be increased by about 500 m3/feddan and 200 m3/feddan for the first and second categories, respectively. The study recommends rationalizing the quantities of production elements needed to grow a feddan of faba bean in Ismailia Governorate as follows: reducing the amount of seeds, the amount of nitrogen fertilizer, and the amount of phosphate fertilizer by about 10, 5, and 50 kg/feddan, and increasing the amount of irrigation water by about 500 m3/feddan, as well as reducing the number of workers. The required amount for cultivation is about 8 workers per feddan compared to the recommended quantities.
