The research aimed to investigate how to realize banana production efficiency with the use of chemical fertilizers in the new lands of Behaira and Menofia Governorates, in addition to assessing the economic impact of using such fertilizers on Williams Banana productivity based on the data collected from 31 orchards in the two governorates.
The physical and chemical characteristics of soil and the plant nutritional status have been assessed. Results of plan analysis indicated deficiency in phosphorus and potassium with contrary to nitrogen which was found sufficient. The average quantity of applied active units of nitrogen, phosphorus, and potassium per feddan were estimated at 0.218, 0.180, and 0.134 respectively. In addition, the measured dispersion coefficients of fertilizer units indicate large variation between banana farmers in new lands under studied, which may be attributed to the variation in the physical and chemical characteristics of the cultivated land. The estimated production function for active fertilizer units indicates that the active units of nitrate, phosphate, and potassium fertilizers are responsible for 69% of the occurring changes in banana production in the mentioned new lands. On the other hand, the estimated production function for different fertilizer units indicate that the active units of nitrate, phosphate, and potassium fertilizers are responsible for 52%, 59%, and 15% of the occurring changes in banana production respectively. Moreover, the estimated elasticity of production for azot, phosphorus, and potassium elements indicate that these elements are used within the economic stage, i.e., all the chemical fertilizers used in banana production in new lands in Behaira and Menofia governorates are used rationally and as recommended, which allows obtaining the maximum productivity of banana in these lands. Furthermore, the assessed number of active units of azot, phosphate, and potassium fertilizers that realize the maximum marginal product indicate that that quantities of chemical fertilizers used in banana production in these lands are in excess of the quantities that realize the maximum of the marginal product function, which can be attributed to the variation in the physical and chemical characteristics of soil types in these orchards.
In 2005, the total cost per feddan of banana in new lands reached L.E 30 thousand. Labor cost ranked on top of the cost items and represented 27.40%, whilst the cost of chemical fertilizers represented 18.60% and ranked third after the labor and seedlings costs. The costs of potassium sulfate, ammonia sulfate, compound, and super phosphate fertilizers reached L.E 2500, 1600, 1000, and 250 of the total cost per feddan of banana in new lands respectively. In addition, the estimated value added per feddan of banana reached about L.E 4 thousand, whilst the estimated annual average revenue of banana cultivated in such lands reached L.E 4060 per feddan, and the estimated annual average revenue of banana cultivated in such lands reached L.E 812 per feddan. Results also indicate that invest profit realized from banana production in these lands is about L.E 0.14.
