Growing Degree Day (GDD) Maturity Rating System
The GDD maturity rating system is based on heat units. It is more accurate in determining hybrid maturity than the days to maturity system because growth of the corn plant is directly related to the accumulation of heat over time rather than the number of ...
How Climate Affects Corn Production
Temperature Corn can survive brief exposures to adverse temperatures―low-end adverse temperatures being around 32 degrees Fahrenheit and high-end ones being around 112 degrees Fahrenheit. Growth decreases once temperatures dip to 41 degrees Fahrenheit or ...
For optimal yields on mineral soils with subsoil pH greater than 6.0 (generally western Ohio), the pH range should be maintained between 6.0 and 6.8. On mineral soils with subsoil pH less than 6.0 (generally Eastern Ohio), the range should be higher (6.5 ...
Sometimes, plant stands are reduced by disease, herbicide injury, hail, insects and flooding. If crop insurance covers the damage, consult the insurance agent before taking action. When all plants of a field are lost, it is realistic to replant if adequat ...
Late planting reduces the cultural practice options for row spacing, seeding rate, and variety maturity. The row spacing for June planting should be no greater than 7.5 inches. Appropriate seeding rates for the first half of June are about 200,000 to 225, ...
The date of planting has more effect on soybean grain yield than any other production practice. The results of a two-year planting date study conducted in Clark County, Ohio are shown in Figure 5-2. Yield loss resulting from delayed planting ranges from 1 ...
Conservation Tillage & Technology Conference March 14-15 in Ada
The Conservation Tillage & Technology Conference (CTC) will be held in- person March 14-15 at Ohio Northern University in Ada. This year’s conference will feature David Hula, four-time winner of the National Corn Growers Association Yield Contest and ...
‘Warm’ Winter Days…What This Means for Wheat
Across Ohio, the average air temperature was 8-10°F warmer in January and February (so far) (Table 1). Due to these warmer winter temperatures, wheat may appear greener than usual and also raises the question, “Will the vernalization requirement be met?” ...
Mild, Wet, and Windy Next 30 Days
Next 30-days... The theme will be an active next 30-days with above normal temperatures (sometimes more than 20 degrees above normal) along with a series of progressive moderate to stronger weather systems. This will lead to a wet next 30-days with most a ...
