To compare the yields of soft red and hard red wheat in an MRI system.

A completely randomized block design in small plots (5.5 x 50 feet) was used to evaluate the effect of varying wheat type, soft red wheat and hard red wheat, in an MRI system. Agra 962 was chosen to represent soft red wheat because of its high-yield capability (98 bu/A over three years in the Ohio Wheat Performance Test at Bucyrus) and its adaptability to MRI. Hondo was chosen as the hard red wheat, because grain buyers are offering a premium for it, providing quality standards are met.
Agra 962 was seeded at a rate of 1.3-million seeds/A. Hondo was seeded at a rate of 1.5 million seeds/A. Planting was done with a three-point hitch-mounted tool-bar planter equipped with sunflower openers. Six replications of the wheat varieties were planted. Both varieties were planted in 15-inch rows. Soybeans were interseeded with the same planter. Wheat harvest data was from complete harvest of plots done with a small plot combine. Yield was adjusted to a moisture of 13.5%.
| Table 1. Wheat Yield @ 13.5% Moisture. | |
| Treatments | Yield (bu/A) |
| Red wheat | 74.5 |
| White wheat | 67.0 |
| LSD (0.05) | NS |
| F | 3.1 |
| CV (%) | 8.5 |
The wheat yields were not significantly different. Based on this one-year study, Ohio farmers should be able to grow either type of winter wheat under similar conditions with no or minimal yield difference.
