Abstract
The paper presents the results of three years of research on the use of various organic and mineral fertilizers for foliar feeding of Druzhina variety buckwheat in the Oryol region. It is noted that the use of complex organic and mineral fertilizers of LLC Polydon Agro: Alfastim, Polydon Boron, Polydon Potassium Plus, Polydon Bio, Polydon NP for pre-treatment of seeds and leaf fertilizing provides an increase in grain yield by 0.19-0.40 t/ha. The share of this factor influence was 12.8-16.9%, depending on weather conditions during the growing season. The positive effect of seed treatment with the biological stimulant Alfastim on buckwheat yield is shown: grain harvest from 1 ha of crops increased by 0.04-0.31 t/ha.It is established that foliar fertilization with organic fertilizers of LLC Polydon Agro is economically justified: with a small consumption (1.6-5.6 t/ha), additional grain collection provides income from 4.90 to 6.02 thousand rubles/ha.
