Correlative research between crop yield and climatic factors confirms the necessity for careful organization of soil tillage, compliance on cultivation technology, finding appropriate levers for climatic conditions in order to optimally use the abiotic factors necessary for productivity formation and increase. There were established correlations between climatic factors and crop yield depending on agricultural background (organic and mineral fertilizers + NPK), basic tillage of soil (plowing, paraplow), methods for weed control (mechanical, manual and herbicide application) and others.
