Steady warm weather and periodic rainfalls have moved corn along pretty well. Most corn planted here in Georgetown in late April is at V6-7 and has been sidedressed. Fields planted through mid-May are at V5/V6, matching the predicted GDD pretty well.
The next milestone to watch for would be tasseling (VT), which occurs at 1135 GDD. At this stage just consider how weather may determine pollination and later grain fill as another determinant of final yield.
Table 1: Accumulated growing degree-days based on planting dates through May 20th.
|If you planted
V6 = 475 GDD, V12 = 870 GDD, VT = 1135 GDD, R1 = 1400 GDD
