Resumo: |
The sugar-energy sector is among the most important in the Brazilian economic scenario, which is responsible for the production of sugar, ethanol and the generation of electric energy, from the industrial processing of sugarcane. However, factors increase demand for this product. In this sense, it is necessary to search for new raw materials that can complement the sugarcane culture. Highlighting corn, which has a 120-day vegetative cycle, can be grown in sugarcane renovation areas, and its grains can be stored for long periods of time. In this sense, the objective of the research was to evaluate the agronomic characteristics of three corn hybrids, and the grain storage and processing reflexes for ethanol production. The experiment was installed in the experimental farm of the Sacred Heart University (USC) located in the municipality of Agudos in the State of São Paulo in the 2016/2017 harvest. The experimental area was 8000m2, with 16 plots of 450m2 each. Hybrids 2B810PW, 2B633PW and 2B587PW were used. The planting was carried out in October 2016 and the harvest occurred at 150 days after sowing (d.a.s). During development of the culture (45, 75, 90 and 110 d.a.s.) the biometric parameters were evaluated. The grains were stored for 0, 30, 75 and 180 days. In these periods these were ground and immersed in water, adding the α-amylase enzyme, giving the must. The musts were submitted to inoculation by industrial yeast BG-1. The Dow AgroSciences® 2B633PW hybrid showed higher grain yield. After 75 days of storage of the grains, there was a reduction in the amount of sugars present, reducing the fermentative performance of the yeast. It is concluded that there is interaction between hybrids and storage time for the amount of ethanol produced in the fermentation, with 2B633PW resulting in higher contents at 30 days, 2B587PW at 75 days, and 2B810PW at 180 days storage. |
