Taking into account the limited land and water resources and the constant growth of the region's population, a stable supply of food to the population and exports will be achieved through the rational use of agricultural potential and policy. It is to save water resources that agricultural clusters based on digital technologies are considered one of the main strategic directions.

This requires new innovative approaches, such as improving the structural mechanisms for managing irrigation systems, introducing automated information systems with a modeling subsystem that ensures the efficient use of water resources. We will determine how much water savings can be achieved by using modern digital methods of automated information systems using the following mathematical model:

∑ Q𝑖 = AC +

∑ ҚХ𝑖

Where: Qi – amount of total water consumed;

АС – the amount of water used for the population and industrial enterprises; value variable from water consumption standards depending on changes in population and number of industrial enterprises;

ҚХi – amount of water used for agricultural irrigation;

n – number of irrigation methods;

𝑖- irrigation methods (in modes).

The daily water consumption of the population and industry in the Jizzakh region is 112,000 m3, and the annual amount of water is 112,000 * 364 = 40,768,000 m3. Annual water consumption for irrigation in agriculture is 3102500000 m3.

∑ Q𝑖 =

40.768.000 + 3.102.500.000 = 3.143.268.000 m 3

The above analysis shows that the total annual volume of water in the region in the traditional way is 3 143 268 000 m 3.

If we save the total annual water consumption in agriculture by an average of 40%, we can see the results of the ongoing experimental work in the irrigation department of the Sh. Rashidov district: the cultivated area in the region is 32 thousand hectares, in the growing season of 2018, 232 million m3 of water were consumed by traditional method, 140 million m3 by drip irrigation method and 92 million m3 of water saved. If we take this figure per 1 hectare, then 2500 m3 of water is saved.

The analysis shows that the total water consumption for traditional irrigation of agricultural crops in the region is 3102.5 million m3, and when using drip irrigation, water savings are 40%, i.e. 1241.5 million m3 of water. If we calculate the results obtained in the region throughout the republic, it becomes clear that the use of modern technologies will save water resources, which is a big problem in the country.

1- size Developed software (database)

The main goal of solving the above mathematical expressions is to create a database for the development of scientific and practical proposals and recommendations for the rational use of water resources when irrigating crops using various technological irrigation regimes and to educate the mechanism of operation of this database.

When analyzing the choice of crop types and their water consumption needs, it was found that the republic does not have enough water resources to irrigate crops at the level of demand. To address this issue in practice, we have developed a variant method for conducting a comparative analysis of a set of crop types and their corresponding water consumption and gross income from them.

Based on the data for all the options discussed above, you can see how close the crops' water requirements are to the established limit. At the same time, it is advisable not only to save water resources, but also to improve the harvest, taking into account the real incomes of the population in the regions. In the table data, each option was analyzed accordingly, taking into account the same sown area. However, as the number of crops decreases, the area of the remaining crops increases, so the total area is considered constant, and the total water consumption is 55.515 m3. We select all types of crops and a limit in relation to this quantity, i.e. the limit will be less than the required quantity as stated above (46.000 m3). In addition, crop yields in the options and the market price of the crop were analyzed.

Our proposed method for systematic analysis of the considered options is based on the fact that in all options, first of all, it is possible to analyze the set of crop types that can be selected around water limit indicators, and how stable the resulting gross income is. Thus, in the chosen option, it is possible to select types of crops and conduct a general comprehensive analysis of gross income accordingly, and on the basis of these analyzes to scientifically substantiate the policy of rational use of water.
