The total output of starch in variants of the experiment varied from 4217 to 5205 kg/ ha when growing Tronka variety. The starch output from the grain yield of Artemisia variety varied from 2570 to 3054 kg/ha or by 1.6–1.7 times less than in Tronka variety. At the same time, the best indicators were provided by variants of retail application of nitrogen fertilizers. Increasing starch output is due to the increase of grain yield of winter wheat.
It is found that the ethanol output varied depending on the variety of winter wheat and fertilizers. Thus, on average over three years of studies on the yield of Tronka variety the output on the unfertilized areas was 2455 l/ha. However, the greatest output of ethanol was obtained after retail application of nitrogen fertilizers – 3081-3147 l/ha, compared to 3016 l/ha when single nutrition. Due to lower grain yield in variants with pair combinations compared with a full mineral fertilizer, there was lower ethanol output (2962–2938 l/ha) or less by 25–78 points.
The ethanol output from the grain yield of winter wheat of Artemisia variety was significantly lower (by 1.6 times) compared with Tronka variety and varied from 1580 to 2023 l/ ha, depending on the variant of the experiment.
Thus, it is the most effective to use Tronka variety grown using N60S35+N60 on P60K60 ground as significantly higher yield of ethanol (3147 l/ha) is received.
