The article discusses the issue of government support for reclamation activities in the context of new challenges of the economic environment. The relevance of the issue is due to the need for intensive development of the agricultural sector caused by globalization processes, which have created fierce competition, both in the international and domestic food markets. Sustainable production of agricultural products on irrigated lands is one of the main indicators of the efficiency of the agro-industrial complex in areas of risky agriculture, including the Republic of Tatarstan. The purpose of the article is to develop recommendations for improving the efficiency of irrigated agriculture whose development depends on the stability of agricultural production and food security. The study aims to identify trends in the development of land reclamation at the regional level and substantiate measures aimed to improve the economic efficiency. The paper presents results of the analysis of development of land reclamation in the Republic of Tatarstan, identifies directions of its development, provides recommendations for ensuring sustainable growth in the volume of reclaimed land and agricultural products, income from the sale of products obtained through irrigation. The research results can be used to develop programs aimed at the development of federal and regional food markets, organizational, economic, technological measures to improve the efficiency of agricultural production, rural areas and the provision of high-quality food supply to the population.

Subject. This article deals with the issues of optimal use of agricultural land. Objectives. The article aims to develop measures aimed at the development of irrigated agriculture in the Republic of Tatarstan. Methods. For the study, we used the abstract-logical, empirical, and statistical methods, and a case study approach. Results. The article assesses the economic efficiency of irrigation reclamation in the Republic of Tatarstan and proposes certain measures to accelerate the development of the reclamation industry in Russia. Conclusions. In the context of geopolitical risks and the sanctions regime, the development of agriculture is of strategic importance for the preservation of Russia's economic independence.

Application of biological preparations and liquid fertilizer-stimulating compositions is a perspective direction of acceleration of growth rates of production of sunflower oil raw materials in soil and climatic conditions of the middle Volga region owing to the following reasons: they stimulate the growth capacity of shoots and accelerate the transition of plants to autotrophic nutrition. As a result, a powerful deep-penetrating sunflower root system is formed, which provides additional sources of food and moisture from such deep layers of soil that are completely inaccessible to cereals; antibiotics produced by biopreparations and chelate form of copper reduces infection of seeds and crops by pathogens of basket and root rot. The number of affected plants is reduced by 35-38% depending on the varietal characteristics of the culture; a positive merger of two factors (additional nutrition and protection of plants from diseases) in one direction is the basis for the formation of highly productive agrocenoses, providing additional production of 0.26-0.27 t/ha of sunflower oil seeds (132-138 kg/ha of vegetable oil).

Subject. This article discusses the issues of sustainable production of agricultural products in the zones of risky farming. Objectives. The article aims to analyze the development of the land-reclamation industry in the Republic of Tatarstan and develop recommendations to improve its economic efficiency. Methods. For the study, we used analysis and synthesis, and the abstract-logical, statistical analysis, and graphical methods. Results. The article identifies trends in the development of land reclamation at the regional level, substantiates the necessary priority measures to improve its economic efficiency, and offers recommendations for ensuring sustainable growth of agricultural production. Conclusions. By complying with all agrotechnical requirements and organizing irrigation, farms can increase potato yields. When irrigating, the cost of production is lower than without irrigation.

An application of the calculated doses of mineral fertilizers, based on botanical composition of goat’s rue herbage, increases a gross yield of crude protein, crude fat and feed units to 48-57% in comparison with the control samples.
