Efficiency of Applying Combined Fertilizers of Complexon and 20:20:20 (NPK) in the Potato Sowings

Abstract

According to the field experiments it is possible to provide high potato yield in case of applying complexon or 20:20:20 (NPK) at least twice through foliar nutrition after introducing the mineral fertilizers in the soil during the vegetation period.
When treating with complexon, the tuber yield surplus makes 91 c/ha – 108 c/ha and 31 c/ha – 46 c/ha respectively
as compared to the similar index of the control variant and N120P90K90. The yield surplus has been promoted by the increase of quantity and weight of large and mid-size tubers. The qualitative indices and marketable state of the tubers have also improved.
It is recommended to introduce the experimentally justified variant in the production.
