| Abstract | Aim.The article is devoted to the determination of medium ripeness grape varieties possible yield in the natural zones of Ukraine according to agroclimatic conditions. Methods.The research was carried out on the basis of ten-day average long-term data on the duration of sunshine, average temperature, amount of precipitation and reserves of productive moisture in a meter layer of soil in the warm period in the natural zones of Ukraine using the method of mathematical modeling and the concept of maximum productivity of crops. Results. The article presents the results of the study of the variability of indicators of agro-climatic resources during the growing season of grapes of average ripening in the natural zones of Ukraine. The difference in the amounts of photosynthetically active radiation, sums of temperatures, amount of precipitation, Selyaninov hydrothermal coefficient, reserves of productive moisture in a meter layer of soil by natural zones was estimated. Based on the application of the concept of maximum plant productivity and the method of mathematical modeling by indicators of light, heat and moisture resources, the values of potential or maximum possible and climatically possible yield are determined by two methods. The difference in these yields is estimated, which indicates the level of use of agro-climatic resources. Conclusions. As the data show, in almost all zones, the level of modern grape harvests on farms is lower, which indicates the possibility of its increase due to the rational selection of varieties and the improvement of cultivation technology. According to the research methodology presented in the paper, it is quite possible to significantly detail information on the yield of grapes of different groups of varieties provided with agroclimatic resources within individual land plots and for future years in connection with climate change. | ||
