Agriculture is an important area of economic development and plays an important role in solving the socio-economic and political problems of the country, especially in the employment of people living in the regions.This study examines the contribution of investments , used mineral fertiliizers to plant production in Azerbaijan Republic by using 23 observations. The EViews 12 software package was used for regression analysis of these models. For investigation of the stationarity of time series, the extended Dickey-Fuller test was applied. In order to analyze the adequacy of the model, the results of the coefficient of determination, F-Fisher test, T-Student test were analyzed. Appropriate statistical methods were applied to identify the model and check its significance for each parameter, to determine adequacy. Necessary statistical procedures have been implemented for authentication of the established models, evaluation of parameters, verification of adequacy. In recent years, the number of people employed in agriculture and its share in total employment has been increasing, contrary to the general patterns that have developed in the practice of world agricultural development, as well as trends.
