THE INFLUENCE OF CLIMATIC CONDITIONS ON PROFITABILITY OF APPLE PRODUCTION UNDER REPLANTATION CONDITIONS AND CROP ROTATION

Abstract

The production of apples is conditioned by many environmental and economic factors, including the cultivated variety, the condition of the plants, the stress factors, demand, supply, costs incurred, prices of fruit and means of production. The aim of the study was to analyse the influence of climatic conditions on the profitability of production of apple trees of the Najdared cultivar. Between 2015 and 2017 an experiment was conducted on apple trees growing on replantation soil and on crop rotation soil in Wielkopolska Region. The analysis of climatic conditions indicated significant differences in air temperatures and precipitation in particular years. When analysing the profitability of the production of apples, it was found that significantly more favourable financial results are obtained on the soil after crop rotation compared to the production on replanted soil. Moreover, the decrease in the profitability of apple production of the trees grown on the replantation soil, especially during unfavourable weather conditions, was greater than the trees grown at the crop rotation soil. On the basis of the research, it was found that in the future, sustainable cultivation of apple trees should be carried out on sites after crop rotation.
