Harvesting corn stover during the dent stage, instead of the usual late stage, boosts ethanol production. Researchers aimed to maximize ethanol yield from corn stover by changing the harvest time. By testing a process called L + SScF, they found that corn stover picked during the dent stage can yield more ethanol. The theoretical ethanol yield from dent-stage stover reached 9.92 t/ha, higher than the conventional harvest time. When they harvested the stover in the dent stage and processed it, they obtained 1.64 times more ethanol compared to standard harvesting. Harvesting corn stover at the dent stage leads to a significant increase in ethanol production, highlighting the critical impact of harvest time on ethanol yield.
