Abstract. In recent years, changes in climatic conditions are becoming more pronounced due to global warming on our planet: increased rainfall in autumn and winter, increased air temperature during the winter, more often and longer become droughts in the summer. The main sources of replenishment of soil moisture are precipitation and water supply from groundwater. Of particular importance for chickpea is the supply of available moisture for the period of spring inspection of crops, that is, 10 days after the resumption of spring vegetation. Significant reserves of moisture during this period, mainly provide the formation of high yields, even with a small amount of precipitation during the spring-summer period. Direct and indirect conditions are interrelated and have a great influence on the yield of plants. Each individual condition or plant life factor may be insufficient (minimal) for plant growth, optimal (when the greatest yield of plants is observed) and excessive, maximum (when toxicosis is observed and the yield of plants decreases). For any plant, both deficiency and excess of some factor (for example, a battery) is harmful. The most favorable conditions for plant life and obtaining high yields are created by the optimal influence of the factor. However, the factors determining the development of plants do not act in isolation, but in combination. Optimal fertility corresponds to the optimal ratio of factors. In different soil-climatic zones, the conditions that determine soil fertility are different. The lack of moisture and nutrients affects sandy soils, and low aeration and high density of soils affect heavy loamy ones. Thus, fertility is limited by various conditions related to soil formation factors. For the first time in the conditions of the Northern forest-steppe of the Tyumen region, the influence of the main tillage on the reserves of available moisture in the cultivation of chickpea is studied. This article presents the reserves of available moisture in the cultivation of chickpea in the Tyumen region.
