Regional Updates: September 19 – 25

Farm Science Review is wrapped up and soybean harvest has just begun. Waterhemp escapes and volunteer corn continues to be reported in soybeans, though many fields are clean. Tar spot of corn is still progressing in fields, and now is the time to start scouting for ear molds. Keep reading below to find out what OSU Extension Educators and Specialists are observing in fields across the state.

Northeast Ohio
Andrew Holden of Ashtabula County reported on behalf of Agronomic Crops Team members representing Northeast Ohio that the majority of soybeans are approaching full maturity and are in good condition. Corn has reached the black layer and is in fair condition. Haymaking and corn silage are wrapping up, and early planted beans are beginning to be harvested followed by wheat planting.

Central & West Central Ohio
Ryan McMichael of Mercer County reported on behalf of Agronomic Crops Team members representing Central & West Central Ohio that corn is between growth stages R5 (dent) and R6 (black layer) and soybean between R7 (beginning maturity) and R8 (full maturity). Both corn and soybean are in good condition, despite current dry conditions. Main field activities include tile installation, corn silage harvest, and early soybean harvest.

Northwest Ohio
Clint Schroeder reported on behalf of Agronomic Crops Team members representing Northwest Ohio. April-planted corn is rapidly drying down and fields planted in mid-May are at or near physiological maturity or black layer. Early soybean yield reports are encouraging, ranging from 60 to 70 bu/ac at 12.5% to 14.5% moisture in parts of Northwest Ohio. Corn silage harvest and 4th cutting of dry hay continued this past week, and red clover that was frost-seeded into winter wheat is now being harvested for forage use.

Southwest Ohio
Ken Ford reported on behalf of Agronomic Crops Team members representing Southwest Ohio. Soybeans are beginning to dry down over this past week. Very few pockets of harvest have been completed on some early-planted soybeans. With the continued dry and warm conditions harvest in the southwest will drastically ramp up this week, depending on what moisture we get from the scattered showers in the forecast. Corn is still a concern for some parts of the region as the Mid to Late May planted corn is still struggling to reach the black layer status. In particular, one farmer pulled out of chopping silage as the corn had not reached an acceptable maturity. April planted corn is maturing and drying rapidly and harvest of this corn will also begin to ramp up this week.
