Study of the influence of climatic parameters on the yield of potatoes under irrigated conditions of the steppe zone of the Southern Urals

The article presents data from a study of the influence of climatic parameters on potato yields in irrigated conditions of the steppe zone of the Southern Urals.

Introduction. The relevance of the study is determined by the need for optimal selection of the assortment of potatoes for each specific region; this is one of the main factors determining the increase in yield and quality of both food and seed potatoes. To achieve this, it is necessary to use varieties in production that combine high adaptability to abiotic environmental factors with resistance to pathogenic organisms. The article presents data from a study of the influence of climatic parameters on potato yields in the irrigated conditions of the steppe zone of the Southern Urals.

Object. We analyzed the relationship between potato yields of 10 different varieties and air temperature during the growing season.

Materials and methods. Field experiments were carried out on 10 potato varieties (Solanum tuberosum L.) – Tarasov, Kuzovok, Red Scarlett, Gala, Udacha, Braslet, Rozara, Agat, Nevsky (standard), Spiridon (standard), in a randomized design with divided plots with four repetitions. Results and conclusions.

Results and conclusions. 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 “Udacha”, “Gala”, “Agat”. The relationship (r2) of potato varieties “Udacha”, “Gala”, “Agat” with air temperature during the growing season has a strong, reliable positive correlation. According to the data obtained, these varieties are considered to be the most drought-resistant, that is, when exposed to positive air temperatures, these potato varieties have good yields.
