| Several recent studies have shown that corngrown in row spacing less than 30" may produce greater yields. However,further research is needed to understand the effect of row spacing andthe interaction of other factors on corn productivity. |

| With funds from the Corn Marketing Program of Michigan, a variable row width planter was built in 1997. Thisplanter is capable of planting corn in 30, 22, and 15 inch rows. The row spacing can be changed in less than one minute. The planteralso allows for immediate changes in seeding rate while in operation. This planter has made it possible for researchers to conduct small-plotresearch on row spacing and plant population in replicated trials. |
