ANALYSIS OF THE ECONOMIC EFFICIENCY OF DRIP IRRIGATION AND EXPECTED CHANGES

Abstract

Annotation. The article presents the results of research works obtained by irrigation of apple trees in various ways during the development of drip irrigation technology of a young intensive apple orchard on thin-layer gray soils of Zhambyl region. During the growing season, the following indicators of a young intensive apple orchard were determined: total water use of apple trees, average daily water use of apple trees and indicators of the effectiveness of drip irrigation compared to the systematic irrigation method. Currently, one of the most difficult issues in land development is the use of semi-desert lands. Kazakhstan belongs to an insufficiently watered zone. Therefore, despite the natural conditions, in order to obtain high crop yields, it is necessary to pay attention to increasing irrigated areas and develop optimal technologies for their proper development. Choosing an effective irrigation method will allow you to get a rich harvest in the future. The article shows forecasting using mathematical modeling of efficiency in terms of price and the possibility of changing the calculated indicators depending on the volume of water discharged for two water options. Also, comparing the indicators, it can be seen that both forecasts have the same result and forecast accuracy. As a result, it can be seen that with the rational use of the drip irrigation system, the possibility of saving water costs per 1 hectare is high from year to year.
