Without doubts, a balance between the application of pesticides, productivity and soil health control is essential for assuring sustainable agricultural performance. Nevertheless, pesticides proceed to be a critical tools for worldwide food guarantee, but their negative consequences should not be ignored precisely when sustainable agriculture is the worldwide target. The purpose of the present article is to present a statistical analysis using a parametric and a nonparametric correlations coefficient in order to study the effect of using three categories of pesticides: insecticides, fungicides, herbicides from 1990 to 2022, in the South-East region of Romania and the productivity of: barley, rape and soybeans. During the studied period, the quantity of pesticides per hectare is the following: insecticides 30.67 kilograms of active substance/ha; fungicides 103.81 kilograms of active substance/ha and herbicides 45.16 kilograms of active substance/ha. The statistical analysis shows that the highest correlation between insecticides and herbicides is that with barley of 0.816 and 0.860, while for fungicides is with rape - 0.683.
