YIELD AND QUALITY OF GRAIN OATS OF COMPETITIVE VARIETY DEPENDING ON PRE-SEED TREATMENT OF SEEDS WITH COMPLEX MICROELEMENT FERTILIZERS AND BACTERIAL PREPARATIONS
Exogenous treatment of seeds with microelement fertilizers and bacterial preparations provides optimal conditions for the formation of the photosynthetic activity of oat agrocenoses. The maximum leaf surface in the sweeping out phase of the panicle formed crops in variants with Megamix-Seeds on a fertilized background - 49.2 thousand m 2 / ha, photosynthetic potential - 4.71 million m 2 days / ha, the net productivity of photosynthesis - 5.97 g / m<sup>2</sup>. The maximum productivity of the panicle (0.96 g) of oats was when seed was treated with Megamix-Seeds on a mineral background, the control was 0.76 g, and the weight of 1000 grains was 46.5 g. in the control variant on a natural background 2.75 t / ha, on the fertilized one - 2.98 t / ha. The highest grain yield (3.76 t / ha) of oats was obtained on the mineral background N60P60K60 when treating seeds with the microelemental fertilizer Megamix-Semena. The reliable yield increase compared to the control was 0.78 t / ha (26.2%). A similar yield (3.71 t / ha) was obtained in the variant with seed treatment with the Tsitovit preparation. A rather high increase in the yield of oat grain was obtained by enriching the seeds with Agrik's bacterial preparation together with microelements and azotobacter - 0.72 t / ha (24.2%). Exogenous treatment of seeds with microelement fertilizers and bacterial preparations contributed to an increase in the protein content in grains on a mineral background - 1.1-1.5%. The largest collection of protein per hectare (616.6 kg / ha) was obtained when oat seeds were treated with Megamix-Seeds on a mineral background.
