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/cm3at 0-50 cm, and it was 41 g/cm3at 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/cm3and 1.42 g/cm3, and on pistachio, it was 1.32; 1.36 and 1.43 g/cm3, correspondingly.

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.

In this article, in the conditions of light gray soils of Andijan-37 and Sultan varieties of cotton, before additional application of mineral fertilizers (every 3 years) 6,000 kg of bentonite per hectare is cultivated with Andijan-37 variety of 1,000 seeds weighing 2-3 g/ha, fiber yield 0,7%, increase in cotton yield by 3.0-3.5 q/ha, in the Sultan variety of cotton the weight of 1000 seeds by 5 g, fiber yield by 1.4%, cotton yield by 4.1-4.5 q/ha observed an increase in Due to the early ripening of the cotton crop 7-10 days and its 90-100% compliance with the requirements of the first industrial variety, saving 20-25% of available resources, the net profit per hectare is 150-105-75 kg/ha of mineral fertilizers used in the Sultan variety of cotton. There is information that in comparison with the usual technology fed on norms increased by 192,197 and 553,113 UZS, cotton of Andijan-37 variety increased by 468,048 and 553,148 UZS.

The highest yield of the promising cotton variety Pakhtakor-1 was achieved by irrigating the cotton with placing black plastic film. Accordingly, the average yield for 3 years was 37.2 q/ha, which was more by 7.9 q/ha than the control variant, whereas it was higher by 2.7 q/ha than Bayaut-2 variety of cotton, in which the same irrigation method was applied. It was found that in Pakhtakor-1 variety, fiber yield was 38.1-39.9%, followed by fiber length 33.5-34.0 mm and weight of 1000 seeds was 115-120.1 grams. Cotton fiber yield, fiber length and weight of 1000 seeds in Pakhtakor-1 for the three years were higher by 0.2-1.0 %, 0.1-0.7 mm and 0.4-1.6 mm, correspondingly, than the standard An-Bayaut-2. The highest economic efficiency of cultivating standard An-Bayaut-2 and promising cotton varieties Pakhtakor-1 through various irrigation technologies was achieved in the form of irrigated with black plastic film, accounted for net profit of 1943902 sums/ha (45 % profitability rate) and 870,583 sums of additional income (17.2 % the profitability rate) than the control.

Studies have found that the sub-surface method of winter wheat irrigation halves the number of irrigations and reduces the crop water consumption by 970-1015 m3, inter-row treatment procedures, and the consumption of fuels and lubricants. The productivity of winter wheat grain in comparison with the control (without sub-surface irrigation) is increased by 0.9 t/ha, environmental pollution from agrochemicals is prevented. The sub-surface irrigation method in conditions of meadow soils with a groundwater level of 1-3 m and mineralization of 1-3 g/l experimented in this paper and the influence of this method on the development dynamics of winter wheat (Polovchanka) on obtaining high yields was also tested. The number of irrigations increased to 6-7 times instead of 3-4. Therefore, on such lands, we recommend while designing the drainage system, the designers should plan the depth of the drains no more than 1.5 meters. Sub-surface irrigation is a temporary closure of closed drainage during the growing season of winter wheat, leading to an increase in groundwater level (80-130 cm), thereby leading to an increase in the moisture reserve in the soil.
