Abstract

According to experts worldwide, more than 700 million people need water reserves, and more than 1.7 billion households living in river basins need additional sources of clean water. Therefore, it is necessary to widely implement water-saving technologies in the irrigation of almonds and pistachios. In this regard, it is important to grow a rich and high-quality crop from agricultural crops through the rational use of Natural Resources, the widespread introduction of water-repellent technologies. More than 700 million people need water reserves, and more than 1.7 billion households living in river basins need additional sources of clean water. Noteworthy, the obtained data on wheat productivity were analyzed mathematically and statistically using the method of dispersion analysis in the manual “Methodology of field experience” by B.A. Dospehov. It was found that the soil of the experimental field had a humus content of 0.746%, followed by total nitrogen content was 0.088% and total phosphorus was 0.212%. According to the results, in 2014, when almonds were irrigated in the order of 60-65-60% relative to LFMC, the volume mass in the 0-30 cm layer of the soil was 1.30 g/cm³, followed by 1.34g/cm³ at 0-50 cm, and it was 41 g/cm³ at 0-100 cm. When irrigating almond in the order of 70-75-65% compared to LFMC, it was equal to 1.30 g/cm³, 1.34 g/cm³ and 1.42 g/cm³, and on pistachio, it was 1.32; 1.36 and 1.43 g/cm³, correspondingly.
