Effect of organic fertilizers on buckwheat yield

The paper discusses the effect of pre-sowing treatment of buckwheat with organic fertilizers on its structural indicators, yield and susceptibility to root rot. It was found that fertilizing has a positive effect on growth, development and yield of buckwheat in comparison with the control. Potassium humate was revealed to be particularly effective and showed the yield range from 3.2 t/ha in Chishminskaya and Barynya varieties and to 4.0 t/ha in Devyatka variety.
