Abstract
This paper presents the results of field experiments to study the effect of fertilizers on the quality of potato tubers of the Tien Shan, Gala, Alladin and Innovator varieties grown in the foothill zone of south-east Kazakhstan. The novelty of the research lies in the fact that for the first time in Kazakhstan she is studying the effect of fertilizers on the quality of potato tubers of four varieties grown in the foothill zone of the south-east of the country. The results obtained can be used to develop recommendations for the use of fertilizers for potatoes in this region. The results of the study are consistent with data from similar studies conducted in other regions of Kazakhstan and other countries. It has been established that the application of fertilizers helps to increase the content of dry matter, starch and total sugar in potato tubers. At the same time, the greatest starchiness of the tubers was noted when applying increased doses of mineral fertilizers or the combined use of mineral and organic fertilizers. The nitrate content in potato tubers of the Tien Shan, Gala and Aladdin varieties did not exceed the maximum permissible concentration (MPC - 250 mg/kg). In the tubers of the Innovator variety, the nitrate content was below the maximum permissible concentration, even in the control. Fertilizer application is an effective way to improve the quality of potato crops.
