Our team’s observations have been that corn maturity has been lagging a bit due to the cool temperatures in August. In some areas, GDD accumulations have been lower than normal by 150 to 200 GDDs. Also, corn planting in some fields was delayed this spring. As a result, silage harvest has been delayed and there could be delays for some crops reaching black layer before frost. The forecast of warm temperature during the next two weeks, though, should help with the maturity issues. We have some concerns that warm temperatures could result in a more rapid drydown of corn planned for silage harvest. Now is the time to monitor maturities and dry matter concentrations in the remaining silage fields to avoid harvesting silage that is too dry.
Full season soybeans seem to be maturing slightly later than normal but I don’t see any serious maturity risks for them. Now is a good time to assess your maturity choices in full season soybeans. Earlier maturing soybeans allow for timelier planting of wheat.
Double crop soybeans in some areas are more at risk for maturity issues. If soybeans are not expected to mature or are forecast to be low yielding, then a forage harvest may be a better options. Soybean harvested for forage can result in a forage similar to medium quality alfalfa. Normally it takes about 12 days to progress from Growth Stage R5 (Beginning seed) to R6 (Full seed) and another 12 days to go from R6 to R7 (Beginning maturity).
