Are Twin Rows for You?

Twin row crops are planted with a staggered seed drop. This allows for more growing room for each individual plant, and it allows each plant to have greater access to water and nutrients, improved light interception, and improves the plants ability to cope with stressful conditions that may develop throughout the season.


Twin Rows are usually planted 7 ½” inches apart on 30” centers. This allows for much better spacing between plants. For example dropping 33,000 seeds per acre in 30” rows would result in 6.3” between plants, the same 33,000 in twin rows would result in 12.6” spacing between plants. This is even more impressive when we go to higher populations, 40,000 seeds per acre in 30” rows puts seeds at a spacing of 5.2” while the same 40,000 seeding rate in twin rows would have 10.5” between plants.

We conducted yield trials across 20 sites last year to compare yields of twin rows and traditional 30” rows. Or results showed at the lower populations there was little response, but at higher populations (above 30,000) we were getting 3 to 5 bushel response to twin rows. Some studies in other areas are showing as much as a 15% yield increase.

As you travel around the Corn Belt this next year, you may see corn fields that look a little different. Our Trelay District Sales Managers have a lot more information on twin rows available, so give them a call today.
