Later planted fields (mid-June) should be undergoing pollination, but temperatures this week are in the low 90s, possibly affecting pollination. Most fields planted in late May were pollinating during ideal conditions, although weather and soil moisture could certainly vary across the state. If you have good records of when you have planted, take a look in a week or two and check for tip-back or aborted kernels along the ear. Fields planted in early April may be in blacklayer within the next week to ten days, if we keep getting about 30 growing degrees per day. Let us know if you see anything sooner. In the last week we have actually seen lighter rainfall every few days, instead of intense storms or extended drought. It is still a good idea to check soil moisture levels and irrigate if necessary.
VT: 1135 GDD – Pollination can begin
R1: 1400 GDD – Silking, pollination
R6: 2700 – Blacklayer
