Agriculture is the basis of the Tajik economy. Since independence, various studies and developments have been carried out in this area. At the moment, the task of the government is the dynamic development of the agricultural sector. The article presents an econometric analysis of the dynamics of grain crop yields for the period 1993–2020, which is associated with the amount of fertilizers applied. The main purpose of this work is to check whether there is a relationship between the application of mineral and organic fertilizers and the yield of grain crops. Through the application of of multiple linear regression the dependence of the grain crops yields on the amount of organic and mineral fertilizers applied in the agricultural sector of the country was revealed. Statistical tests, such as the Fisher and Student, Goldfeld – Quandt and Darbin – Watson distributions, were used to determine the reliability and accuracy of the application of multiple linear regression. According to the results of the Goldfeld – Quandt test, it is proved that there is no heteroscedasticity in this model. Using the Darbin – Watson criterion, it was found that this model lacks autocorrelation. The relationship between the dependent variable and independent parameters indicates that for a sustainable process of agricultural production, it is necessary to ensure the targeted application of fertilizers necessary for grain crops.
