Abstract
Soil salinization is a major soil degradation process threatening ecosystem and is recognized as being among the most important problems at a global level for agricultural production, food security and sustainability specially in arid and semi-arid regions. Egypt is apart from this scene. Salinity is a continuous challenge in Egypt because of the dry climate, In addition to the anthropogenic activities involving inappropriate management of land and water resources. Accumulation of excessive salt in irrigated soils of Egypt negatively affects crops yields, reduce the effectiveness of irrigation, deteriorate soil structure, affect other soil quality and threatens agricultural sustainability by limiting agricultural productivity and profitability. The study used data of survey conducted in South El Husainia Plain (Egypt) in 2019/2020 to calculate some economic indicators.This study aims to measure economic efficiency for the main crops grown by the sample farmers, Identify the general characteristics and the main crops cultivated in the target Site representing the salt-affected land located at South El Husainia Plain, identify and analyze the economic efficiency for the main crops cultivated in the target Site, studying the production economics of the cultivated crops in the salt-affected land. The results show that Rice emerged as the top crop Cultivated by farmers representing 95.1 percent of agricultural households in summer season, Sugar beet emerged as the top crop cultivated by farmers representing 92.2 percent of agricultural households in winter season. Besides, the average yields of crops cultivated in the target Site were lower than the average yields of the Country due to poor soil fertility and low water supply. Empirical findings showed that growing Sugar Beet, wheat is promising in the study area. Therefore, farmers are encouraged to grow Sugar Beer, wheat and Barseem in winter whereas in summer, they are encouraged to grow Rice, Cotton and Maize since Sugar Beet and Wheat were the most economically efficient crops grown in winter whereas, Rice, Cotton and Maize are considered appropriate crops for cultivation in salt-affected lands in summer. Sugar beet ranked first in terms of high Net Profit per feddan, reaching about L.E. 5177.86 for one feddan, followed by Wheat reaching about 5177.28 Net Profit L.E per feddan. The study recommends that farmers should be encouraged to adopt sustainable water-saving technologies and land conservation practices to overcome inappropriate soil conditions, irrigation management and enhance their agricultural productivity and profitability.
