Abstract
To date, the use of fertilizers has become firmly embedded in advanced crop cultivation technologies, as the main component of obtaining high and sustainable yields. The nutritional regime of plants cannot be optimized only with the help of macronutrients. They also need trace elements that can increase the resistance of plants to adverse growing conditions, diseases and pests. However, the high cost of such fertilizers makes it necessary to develop new more effective and less expensive drugs. Therefore, in modern potato cultivation technologies, much attention is paid to non-root top dressing. As a result of three-fold leaf treatments with the developed fertilizer, the yield increase of potato variety Gulliver was 0.4…5.2 t/ha, variety Vimpel 2.0…5.1 t/ha, variety Matushka 0.1…4.1 t/ha.
