دراسة تحليلية للكفاءة الإنتاجية و الاقتصادية لإنتاج محصول بنجر السكر بالأراضي القديمة و الأراضي الجديدة بمحافظة الدقهلية

Abstract EN

Egypt suffers from the relative stability in the land and water resources, which resulted in a competition in the use of these two major resources between strategic crops of the same loop, making the study of productive and economic efficiency to location resources for the production of these crops important in this field.

The problem of the study was to question about Productivity and economic efficiency use of agricultural resources in the production of sugar beet crop in the old and new agricultural lands in Dakahlia Governorate, the research aimed to study the Productivity and economic efficiency of the production of sugar beet crop in Dakahlia Governorate, and through an economic study Production of sugar beet crop in Dakahlia, estimating production efficiency and economic efficiency for the production of sugar beet yield of old and new lands and was reached following results: a.

The productivity of the feddan of sugar beet crop in the sample in the new lands in the governorate was about 19 tons valued at 11,400 pounds, compared to about 23 tons compared to those in the old lands in the province valued at 13800 pounds, and the rate of decline in the new lands reached about 17.4%, with a total return of the feddan in the new lands.

12040 pounds, compared to about 14600 pounds for his counterpart in the old lands, and the rate of decline in new lands amounted to about 17.5%, achieving a net return per acre in the new lands amounted to about 2880 pounds, compared with about 4495 pounds for his counterpart in the old lands, and the rate of decline in the new lands reached about 35.9%, and profitability The pound spent in the new territories was about 0.31, compared with 0.44 for the old one.

b.

The amount of water used for irrigation planted with sugar beet crop in the new lands about 3285 m 3 / acre, compared to about 2850 m 3 / acre, with an increase rate of new land about 15.3%, efficiency of irrigation water use of about 41.6%, 48% in new lands and old lands on The yield per unit of water in the new lands reached 5.8 kg / m3, compared to 8.1 kg / m3 in the old lands, with a decrease in the new lands by about 28.3%, and the net yield per unit of water in the new lands was about 0.88 pounds / m3, compared to about 1.58 LE / m3 in the old lands, with a decline rate in the new lands of about 44.4%.

c.

The results of the estimation of the production function of sugar beet crop in the old land was significant to the effect of the nitrogen fertilizer in kg and the number of human work hours on the yield of sugar beet yield.

The production elasticity of the suppliers was estimated at 0.25 and 0.12, respectively.

The results of the estimation of the cost functions of sugar beet crop in the old lands have been reached to the optimum yield of 23.53 ton / feddan, and the maximum profit production is estimated at 23.87 ton / feddan.

d.

The results of the estimation of the production function of sugar beet crop in the new lands showed that the effect of nitrogen fertilizer in kg and the number of human work hours on the feddan yield of sugar beet.

The production elasticity of suppliers was estimated at 0.22 and 0.12, respectively, and examining the price efficiency show that the use of these suppliers in the production of sugar beet crop is economical.

The results of the estimation of the cost functions of sugar beet crop in the new lands have been reached to the optimum yield of 20.15 tons / feddan, and the maximum profit production is estimated at 20.32 tons / feddan.
