STUDIES OF WATER CONSUMPTION OF VEGETABLE CROPSIN THE CONDITIONS OF ZHAMBYL REGION

Abstract

The scientific article presents the results of a study of the water-use aggregate of crops during irrigation of vegetable crops by various irrigation methods on loamy gray soils of the Zhambyl region. Vegetable crops were watered systematically and drip. For irrigation, a drip irrigation system was used, which has a high water-saving capacity and does not require high funds. The daily and total water use of vegetable crops during the growing season are determined. As a result of the study, it was found that the daily set of water consumption of vegetable crops showed a low indicator in the drip irrigation variant. The total water use of vegetable crops showed high indicators in the variant of systematic irrigation and amounted to 4151m³/ha, and in the variant of drip irrigation 2333m³/ha, that is-1818m³/ha. The total water use of vegetable crops for months showed low rates in the drip irrigation option. The average daily water use of vegetable crops in the drip irrigation variant in June and July was 22-24m³/ha, and in systematic irrigation in these months was 33-43m³/ha. Low average daily water use of crops was observed in the drip irrigation variant in August and was equal to 18m³/ha. The main revenue part of the water balance of vegetable crops was irrigation work. It was found that the total water use of vegetable crops in the variant of systematic irrigation showed a high rate of 44%.
