Abstract

The article presents the results of a study of we analyzed the relationship between the yield of potatoes of 10 different varieties and the air temperature during the growing season: Nevsky (1 St), Spiridon (2 St), Kavaler, Zakhar, Sapfir, Ariel, Kashtak, Krepysh, Lekar’, Fioletik. Our studies have shown that potatoes have specific requirements for irrigation in order to obtain good and high-quality tuber productivity. As a result of the analysis, it was revealed that the yield of potatoes directly depends on water regime, on the amount of precipitation during the growing season. High air temperatures adversely affect the yield of potatoes, but varietal specificity must be taken into account. We analyzed the relationship between the yield of potatoes of 10 different varieties and the air temperature during the growing season. As a result of the analysis, it was found that in most cases, the relationship between potato productivity and air temperature (r2) during the growing season has a negative relationship, with the exception of the varieties "Kashtak", "Krepysh", "Fioletik". The relationship (r2) of potato varieties "Kashtak", "Krepysh", "Fioletik" with air temperature during the growing season has a strong significant positive correlation.
