|Hard red winter harvest is now completed in Texas, Oklahoma, virtually all of Kansas and most areas of southeast Nebraska and southeast Colorado. Northeast Colorado is reporting 30% complete with Nebraska ranging from 95% complete in the southeast to just 10% complete in far western Nebraska.|
Generally, test weights in Texas and the southern half of Oklahoma have been around 59 lbs/bu (78 kg/hl) with proteins above 13%. Test weights have increased from central Oklahoma to the Kansas border. As noted in earlier reports, the lower test weights south of Kansas are very likely a function of a late season freeze and drought that severely affected northern Oklahoma southward into Texas. The higher test weights in Kansas can be attributed to late season moisture received in May during the final stages of plant development. That moisture was not uniform and resulted in a mosaic pattern of test weight and protein values. In some cases, extremes in protein occurred in areas as small as a 15 mile radius.
The unusually cool and wet weather in eastern Colorado and across Nebraska resulted in very good test weights, very good thousand kernel weights and very good kernel diameters, but significantly lower proteins.
