Application of water-saving irrigation technologies of intensive apple orchards in the irrigated regions of Uzbekistan

Abstract

In this article, the purpose of the research is to improve the method of irrigation of intensive apple orchards, determining the rate and duration of irrigation, determining seasonal water consumption, and calculating water rates. When intensive apple orchards are irrigated on the basis of water-saving technologies, it is observed that the trees use soil moisture, atmospheric precipitation, and the efficiency of using irrigation water. As a result, it has been proven that seasonal water consumption can be saved from 12% to 52% compared to furrowlab irrigation. In this case, it was noted that the use of transverse barrier furrows in the conditions of soils prone to irrigation erosion reduced soil particle leaching by 31-51%, irrigation water by 17-25% and increased productivity by 22-28%. Also, it was observed that the fruit quality improved, the weight of one apple increased by 36 g, and the yield increased by 7.3 tons/ha. Intensive orchards irrigated with 75-80-70% relative humidity relative to LFMC have been reported to have 30-65% higher yields than controls.
