Indiana Perspective on Corn Yield Reports

Indiana Perspective on Corn Yield Reports
USDA numbers indicate Indiana harder hit than any other Corn Belt state.

The numbers for corn for the U.S. outlined in USDA's first estimate of the season, August 10, based on conditions as of August 1, wasn't good nationwide. Corn production is estimated own 13% nationally from 2011, which wasn't a great year in its own right. Average national yield is estimate d at 123.4, down from last year's 147 bushels per acre.

Indiana was the hardest hit Midwest state, with Illinois second worst. Greg Matli, deputy chief of Indiana Ag stats, puts Indiana's corn crop at 100 bushels per acre, down 28% from 2011, which was also a rough year with yields well below trend yields.

USDA numbers indicate Indiana harder hit than any other Corn Belt state.

Bob Nielsen, Purdue University Extension corn specialist, says that by his calculations, if the August report is accurate, this will likely be the largest negative deviation from trend yield since 1936, He pegs the corn yield at 38% below trend yield, while '83 was 34% off and '88 as 31% below trend Yield. In 1991, the corn crop was off trend at the time by some 27%. Nielsen says there's a slight possibility corn could recoup a small amount of gain by using the recent rains to increase kernel depth. However, Nielsen admits that the possibility of increasing yields at this point is very slim. Pollination is over, and there is no way for ears to add more kernels. And gains now would be relatively minimal compared to overall yield.

Shaun Casteel, Purdue soybean expert, says there's still time for soybeans to make up ground now that it has rained. Some fuller season varieties should still be flowering and putting on pods if you got timely rains in the past week.

Early varieties are pretty much set, he believes.  He thinks mid-season varieties are set, too, thanks to the tough weather around the Fourth of July. The extreme and dry weather combination caused damage through abortion. Those beans are less likely to react to rains. However, full-season beans my take advantage of these late rains to bump up yields by a few bushels per acre.
