COLUMBUS, Ohio â With late plantings, excessive rainfall, a myriad of insects and diseases and poor plant development, it seemed Ohio corn and soybean growers would be throwing in the towel on another disappointing season. But to the surprise of many, Ohioâs top agronomic crops are outperforming expectations with record yields projected. According to the Ohio Agricultural Statistics Service, as of Sept. 1 the corn harvest was projected at 145 bushels per acre. If the number stays true, it would make it Ohioâs second-highest harvest in history â behind the 147 bushels per acre harvested in 2000. Soybean yields are projected at 44 bushels per acre, nearly an all-time high. By comparison, Ohio growers harvested 88 bushels per acre of corn and 30 bushels per acre of soybeans last year. Only a small percentage of the crops have been harvested so far, but Ohio State University agronomists like what they see. âThe soybean crop is a bit of a surprise. The crop is turning out better than expected despite the weather and diseases,â said Ohio State Extension agronomist Jim Beuerlein. âEvery time we go through one of these years we are amazed at the resiliency of the soybean crop.â Excessive rainfall throughout much of the growing season did little to impact the cropâs development. Early-planted fields (late April through May) are pulling off 40-plus bushel-per-acre yields. Soybeans planted after June 15 may have been damaged by the earlier-than-normal frost that hit Ohio the beginning of October. The later the planting, the greater the loss due to frost, said Beuerlein. âOverall, we had a lot of good things happen to us â thatâs no weeds, good stands and despite a lot of rain, it was good rainfall distribution,â Beuerlein said. Rains did bring disease, and soybeans were plagued with plenty of pathogens. Even so, the crop performed well, said Ohio State plant pathologist Anne Dorrance. âIt was a very challenging year in that samples we received had more than one pathogen associated with it,â said Dorrance, with the Ohio Agricultural Research and Development Center in Wooster, Ohio. âBut all these pathogens tend to be associated with poor drainage, something that growers can remedy by adjusting drain tiles or taking measures to reduce compaction.â In addition to the common Phytophthora root rot, soybeans were also affected by Sclerotinia stem rot, a disease not seen in Ohio for several years, and sudden death syndrome, present in more acres this year than ever recorded. âWe had all these diseases out there, and in some areas there are dead spots and the beans are stunted and not maturing, but overall the bean fields look fairly good,â said Dorrance. âSoybeans have an interesting ability to compensate for lost neighbors. They will get very bushy and take up the space where other plants have been. So at 100,000 plants per acre you will get yield equal to what you would get at 200,000 plants per acre.â Dorrance said wise selection of varieties with a good resistance package to many of the plant pathogens helped boost the crop from under dire environmental conditions. But growers now need to look to next year. âWhat weâve done is increase the population of pathogens in those fields for next year,â said Dorrance. âSo the next thing growers need to do is to rotate their crops. Wheat is an excellent crop to put in those soybean fields. It helps to change the flora and reduces the population of soybean cyst nematode, as well as prevents the rapid increase of Phytophthora.â For those growers who are unable to get wheat in the ground, planting corn or alfalfa makes a good substitute. The corn crop is also faring well, according to Ohio State agronomist Peter Thomison. âWith the environmental conditions weâve had, the corn is turning out to be better than we had expected,â he said. The crop continues to be about a week behind in development due to late planting and a shallow root system, but some of the major issues concerning agronomists have yet to become widespread problems. âMaturity is one issue we are concerned about because of the fairly cool growing season. The crop has not accumulated as many heat units as we would have liked it to,â said Thomison. âBut the crop is showing what some of Ohio Stateâs research has supported: that corn plants when planted on late dates can accommodate a shorter growing season by maturing with fewer heat units.â Another issue is how fast the corn will dry down due to the late-season rains and continued soggy soils. âSurprisingly, a lot of the cornfields planted later than normal and wetter than normal have been drying down faster than expected,â said Thomison. But he urged growers to harvest corn as quickly as possible to avoid any problems with stalk quality. âA lot of fields are standing well, but we know there is stalk rot in these fields because of the rains we had during the growing season. If you pinch the lower nodes some stalks will collapse very easily,â said Thomison. âIt wonât take much for heavy winds or heavy rains to blow the stalks over, so we are encouraging growers to get out there as soon as possible and earmark those fields which they think they may have problems with.â Northern corn leaf blight, anthracnose stalk rot and top dieback are just some diseases that have predisposed the corn crop to stalk quality problems. The early frost may also have impacted late-planted corn, said Thomison. The extent of the injury to the corn plants is still not known and how well the crop will yield because of the damage remains a wildcard.
