Harvest Report - June 15, 2012
HRW

Except for irrigated wheat in the Texas and Oklahoma Panhandles, harvest is winding down rapidly in those states.  The southern half of Kansas is also nearing completion except for far southwestern and northwestern areas where harvest is now in full swing.  Colorado and Nebraska are just getting started with still less than 10% harvested at this point.  Yields continue to be impressive considering the dry hot weather most of the southern Great Plains suffered during the most critical stage of water demand for plant development- pollination through grainfill.  Yields have ranged from the low 20’s to well over 70 bushels per acre with commonly reported averages from 40 to 45 bushels per acre.  Protein has also picked up significantly as harvest reached Kansas, with occasional pockets of low protein in a mosaic pattern.

With 181 samples now analyzed, the data clearly reflects the damaging effects that the hot dry conditions had during the later stages of plant development on kernel characteristics.  The most apparent effect has been in relation to kernel size, with generally small kernels, and with the highest protein areas also having more shrunken kernels and lowest yields.  The areas producing the highest yield, while still having small kernels, have higher thousand kernel weights and lower proteins.  The pattern is mosaic in nature and while it is somewhat related to wheat variety, the more dominate factor was the stage of growth the plants were in when the hot weather occurred and when or if scattered rain showers occurred during that stage of development.  Most areas had little if any stored moisture on which to draw, so any supplemental rain made a big difference.  While test weight did not change this week, protein increased again in the overall average and TKW dropped from last week.
