Pastukh O. Features of agrobiocenosis formation of compatible crops of millet and buckwheat depending on the application of biological products in terms of western forest steppes

The thesis is devoted to study the ways of sowing buckwheat and millet crops including compatible crops of these cultures and the impact of seed pre-treatment with biological products on formation of buckwheat and millet productivity in terms of western forest steppes. Studies indicate that obtaining high and stable yields of buckwheat and millet, high economic and energy efficiency of their growing were ensured by sowing of compatible crops. The greatest effect was provided by symbiosis of buckwheat variety Son 3/02 and millet variety Omriyane, grain yield of crops per hectare was 4,97 t/ha. Research has established that the yield of buckwheat and millet was influenced by biological agents. Thus, the optimal values of cereals yields were at variant with seed treatment with agent Agate 25 K, the indicator of buckwheat variety Son 3/02 was 2,21 t/ha, while millet variety Omriyane - 4,46 t/ha which exceeded the control variants, 0,29 and 0,44 t/ha respectively.
