Table 4. Projected rates of reduction in time to corn maturity (days per decade) in the 21st century for two corn cultivars planted according to business-as-usual date, scenario-1 (14 days before the last spring freeze) and scenario-2 (1 day after the last spring freeze) at three locations in the Northeast United States under two emission scenarios.
Rates are reported as median values across projected data from 9 Global Climate Models.
