Abstract

The realization of the maximum productive capabilities of agricultural crops provides for mandatory compliance with a number of technological situations. Mountainous areas with a temperate climate of the North Caucasus have the best soils for potato cultivation. Optimization of technological parameters of the use of mineral fertilizers for the production of potato seed material in the conditions of the mountainous zone of Kabardino-Balkaria is an important urgent task of modern seed culture. The correct system of mineral nutrition is the key to reducing the impact of the negative consequences of adverse climatic conditions on the plant nutrition and, in general, on the growth and development of potato plants. The introduction of combinations of nitrogen-phosphorus and nitrogen-potassium against the background of increased nitrogen content in the soil does not provide high rates of photosynthetic potential of potato plantings. Optimized application of NPK mineral fertilizers and combination with non-root spraying with a trace element in the budding-flowering phase of potatoes contributes to the production of more seed material and higher quality.
