Sweet corn variety 'Vnesok' is characterized by high starch content, making it especially valuable for bioethanol production. Starch in corn kernels is fully digestible and accounts for about 30% of dry matter, but excessive starch content may reduce feed digestibility, so additives for balancing are recommended when using corn in feed rations. Protein content in corn is low — around 6-7% — which is related to its high yield and focus on maximizing biomass and starch accumulation.

Growing corn variety 'Vnesok' for biofuel requires adherence to specific agronomic practices. Early planting at the end of April — beginning of May allows the plant to develop before drought sets in, which is particularly relevant for steppe regions such as the Dnepropetrovsk region. To maximize biomass and starch accumulation, high planting density — 75–85 thousand plants per hectare — is applied, along with special attention to plant nutrition, particularly phosphorus and potassium, which stimulate starch accumulation. Protection against pests and weeds during early growth stages is also crucial for maintaining yield.

After harvest, corn variety 'Vnesok' is directed to processing for bioethanol. The grain is cleaned and ground, then starch is fermented with yeast to produce ethanol and a by-product — dry distillers' grains with solubles (DDGS), which are used as high-protein animal feed. This process is nearly waste-free and economically advantageous, especially considering the possibility of contract farming and state support. Due to its characteristics and adaptation to local conditions, corn variety 'Vnesok' is a promising raw material for developing biofuel production in Ukraine.
