The Use of Mineral Fertilizers and the Yield of Sugar Beet in the Conditions of the Buinsky Municipal District of the Republic of Tatarstan

Abstract

The article presents the results of an agroecological assessment of the use of mineral fertilizers on sugar beet crops in the Buinsky municipal district over the past eight years (2015-2022). The scientific novelty lies in considering the issue of statistical processing of actual data on sugar beet yields and the level of application of mineral fertilizers for this crop in relation to a specific municipal district, which certainly has practical significance when making management decisions, determining the structure of the specific composition of mineral fertilizers. As a result of the study, the dependence of sugar beet yield on the amount of the main types of mineral fertilizers applied for the period from 2015 to 2022 was analyzed. Correlation analysis of sugar beet yield and the amount of various types of mineral fertilizers applied to this crop revealed the dependence of yield on the amount of potash fertilizers applied.Next, the formula for regression analysis of the dependence of sugar beet yield on the amount of potassium-containing mineral fertilizers was determined. Regression and correlation analyses of sugar beet cultivation have shown that the level of natural fertility of arable soils in the Buinsky district provides only 20 t/ha of root crops. The application of mineral fertilizers ensures the production of 35,5 t /ha of sugar beet. The increase in yield at the same time will be 15,5 t/ ha. The closest relationship between the increase in yield and nutrition elements was observed in potassium-containing fertilizers (coefficient 0.45). A slight tightness of dependence on the Cheddock scale was noted between an increase in yield and the level of application of nitrogen and phosphorus fertilizers (0.08 and 0.11). This causes the fact that the soils under sugar beet are highly fertile and well provided with these nutrients.
