Tillage

https://agcrops.osu.edu/node/4327

Tillage disrupts soil aggregates, and repeated disruption destroys soil structure. It also causes a long-term decline in soil organic matter, which further destabilizes soil structure. Tillage disrupts the continuity of large soil pores and restricts the ...

Producing Soybeans Without Tillage

https://agcrops.osu.edu/node/4333

Growing soybeans in Ohio without tillage has become both practical and profitable, and often reduces or eliminates some tillage related problems. Time savings accrued by eliminating tillage can be invested in earlier and more careful planting or the plant ...

Planting Date

https://agcrops.osu.edu/node/4335

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 ...

Disease Control

https://agcrops.osu.edu/node/4325

EARLY SEASON AND SEED-BORNE DISEASES Phytophthora root and stem rot is the most serious soybean disease in Ohio and is present everywhere soybeans are grown. Damage to the crop by Phytophthora sojae is most prevalent in fields with poor drainage, high num ...

Rhizobium Inoculation

https://agcrops.osu.edu/node/4334

Soybean plants have a symbiotic relationship with bacteria in which the bacteria fix nitrogen from the atmosphere into a plant-available form of nitrogen. In soybeans, nitrogen fixation is associated with Bradyrhizobium japonicum (commonly referred to as ...

Late Planting

https://agcrops.osu.edu/node/4336

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 15 inches. Appropriate seeding rates for the first half of June are about 150,000 to 175,0 ...

Row Spacing

https://agcrops.osu.edu/node/4451

In Ohio, most soybeans are planted in narrow rows (7.5- to 15-inch). Soybeans grown in narrow rows produce more grain because they capture more sunlight energy, which drives photosynthesis. Within limits, as sunlight interception increases, so does yield. ...

Replanting

https://agcrops.osu.edu/node/4338

Sometimes, plant stands are reduced by disease, soil crusting, herbicide injury, hail, insects, slugs, 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 realisti ...

Fertilization Recommendations

https://agcrops.osu.edu/node/4348

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 ...
