From the Rows -- Brian Grete -- Day 2

From the Rows with Brian Grete

Day 2 of the Pro Farmer Midwest Crop Tour took my route west and north out of Fischers through crop districts 5, 4 and 1 in Indiana through the counties of Clinton, Boone, Tippecanoe, White, Benton and Newton. Generally, ear populations were strong, with five of our seven samples over 95 ears in two 30-foot rows, and grain length was good. That's what is needed to build a strong yield. Corn yield calculations from our samples ranged from 140.1 bu. per acre in Clinton County to 222.0 bu., also in Clinton County. The average yield on my route through Indiana today was 179.2 bu. per acre.

When the samples from all 12 eastern Tour routes were tabulated, the Indiana corn yield came in at 167.36 bu. per acre, up 47.8% from year-ago and 18.6% above the 3-year Tour average. Overall, Indiana has a good corn crop, but like Ohio, the crop is going to need late-season rain to hold onto yield potential that's in the field, especially in the driest areas.

As we moved across the border into northeastern Illinois, conditions turned noticeably drier and our yield calculations declined. For our eight corn samples in northeastern and east-central Illinois in the counties of Kankakee, Iroquois, Livingston , Ford and McLean, my route had an average yield of 150.16 bu. per acre, with a range of 123.3 bu. and a high of 185.7 bushels. Ear populations were strong, but grain length was shorter than we saw in Indiana due to moisture stress. Much of the corn we sampled needed a good rain a week or more ago and is going backwards. Given the historical production potential in these counties, the results we found on my route were disappointing. Other routes, however, found better corn south of my route, so it appeared crop variability increased as we moved into eastern Illinois.

For soybeans, the average pod count in a 3'x3' square on my route through Indiana today came in at 1,275, with a low of 888 and a high of 1,593. Aside from the one poor pod count, the bean samples on my route were generally 1,250-plus. Plant health was good on my samples, though we drove by two fields with SDS. Several producers who attended the evening meeting in Fischers on Monday had warned us we'd see some SDS on Day 2.

The soybean pod count in a 3'x3' square for all Tour samples came in at 1,185.14, which is 14.7% better than year-ago and 4.3% higher than the three-year Tour average. The Indiana soybean crop is going to need timely late-season rains to finish strong. Without rains, yield potential will be trimmed by pod abortion.

On Day 3, scouts will head west out of Bloomington, Illinois, en route to Iowa City, Iowa.
