The January Regional Agronomy Meetings will be held on January 17 at Licking County Joint Vocational School, January 18 at Clinton County Fairgrounds Expo Center. Two meetings will be held on January 19 one in Seneca County at the Camden Falls Conference Center, the second at Richland County in the John Hartz Activity Building on the Fairgrounds.

Pre-registration is requested and cost is $20. For more information or to register for these programs visit the Regional Agronomy Meetings web site or call the following phone numbers:

B) 1999 Evaluations of Nutritionally Enhance Corn - Peter Thomison and Allen Geyer CORN Questions

There are several specialty corns currently being marketed for value enhanced grain production. These include the TopCross, Supercede, and NutriDense corns. These specialty corns were developed with improved nutritional traits to enhance the feed value of grain. Nutritionally enhanced grains produced by these specialty corns offer major advantages over No. 2 yellow corn because they contain more protein, essential amino acids, and energy (oil) which can help livestock feeders reduce reliance on costly ingredients and supplements.

Evaluations of the TopCross high oil grain production system have been conducted since 1995. (For information on 1999 TopCross corn performance, consult: OSU Extension Fact Sheet AGF136-99, High oil corn TC-Blend Performance Tests. http://www.ag.ohio-state.edu/~hocorn/af13699.htm

The Supercede and NutriDense corns have been introduced more recently, and we undertook limited testing of Supercede hybrids in 1998. Unlike the TopCross high oil corn production system which involves the use of blends, the Supercede and NutriDense nutritionally enhanced corns are single cross hybrids. The Supercede and NutriDense corn hybrids have been licensed to seed companies for distribution and are registered trademarks of Dow AgroSciences and ExSeed Genetics, respectively.

Evaluations of nutritionally enhanced corns in 1999 were conducted at the OSU-OARDC Research Farm at Wooster in northeast Ohio and the OSU-OARDC Northwest Branch Research Farm near Hoytville in northwest Ohio. Nine nutritionally enhanced corns including two Supercede hybrids, six NutriDense hybrids, and a single cross high oil corn hybrid) from five seed companies were planted at each site (Supercede and NutriDense are trademarks of Dow AgroSciences and ExSeed Genetics, respectively.)  A normal (low oil) single cross hybrid was also included as a check.

Grain yields of the nutritionally enhanced corn hybrids ranged from 164 to 191 Bu/A at Hoytville and 119 to 141 Bu/A at Wooster. At Hoytville, most of the Supercede and NutriDense entries produced yields that were not significantly different from the normal corn hybrids. Yields of most of the Supercede and NutriDense hybrids were comparable. Differences in yield among the specialty and normal hybrids were not significant at Wooster.

Grain produced by the NutriDense, Supercede and single cross high oil corn was characterized by higher oil content than grain of normal corn hybrid (5.9% vs. 4.2% at Hoytville; 6.0% vs. 4.2% at Wooster). There were significant differences in grain oil content among the nutritionally enhanced hybrids at each location with oil levels ranging from 5.4% to 6.8% at both sites. Grain protein levels of nutritionally enhanced hybrids averaged 2.1 percentage points higher than the normal corn at Hoytville, but only 0.4% higher at Wooster. At Hoytville, the nine nutritionally enhanced hybrids exhibited significantly higher grain protein levels than the normal corn, whereas at Wooster, protein levels in the nutritionally enhanced and normal corn grain were generally not significantly different. At both locations, there were significant differences in grain protein among the nutritionally enhanced corn hybrids. Starch levels in grain averaged 3.5 percentage points less in nutritionally enhanced corn compared to normal corn.

C) White Food Grade Corn: 1999 Performance - Peter Thomison, Allen Geyer, David Jordan and Rich Minyo  CORN Questions

White corn is one of several specialty crops receiving greater attention by Ohio growers as an alternative to yellow dent corn. Premiums are available for white corn grown under contract. We conducted a white corn test in Ohio at the OARDC NW Branch at Hoytville in 1999 as part of a multi-state testing program coordinated by Dr. Larry Darrah, USDA-ARS, and the University of Missouri. Results of the 1999 Ohio trial are shown in Table 1. In 1999, 26 white corn hybrids were evaluated along with two yellow check hybrids. Test results provide growers with a basis for comparing the relative performance of commercial white corn hybrids and yellow corn hybrids.

Multi-state white corn yield test program results are published yearly. Data presented in the publication include food quality characteristics as well as the typical agronomic traits. For information about the food corn tests and annual field day check the following web site: http://www.agron.missouri.edu/ars_columbia/fcpt&fd.html

D) Come Get Your Hands Dirty at the Corn and Soybean Workshops - Greg LaBarge CORN Questions

February is the month for in-depth workshops in corn and soybean production at locations around the state. Live plants and practical exercises are a part of this hands-on workshop. A one-day workshop entitled “Soybean Production and Technology Workshop” 9:00 am to 3:30 pm will be presented on February 2, 3 and 4.  The “Corn Production Workshop” 9:00 am to 3:00 pm is scheduled for February 10, 11, 15 & 17. Visit our web site for more information on these workshops: http://www.ag.ohio-state.edu/~corn/2000work.html

Both workshops will cover management issues in crop development. The soybean workshop will also focus on disease management issues.  The corn workshop will have the additional topics of nitrogen management and insect identification and control.

Registration for the “Soybean Production and Technology Workshop” is $15 and is co-sponsored by the Ohio Soybean Council. Registration for the “Corn Production Workshop” is $25. A reference notebook and lunch is included in the registration.

CCA and Pesticide Applicator credits are offered at each site. Dates and Locations for each workshop offered are listed below.
