Is wider row spacing better or is narrow row spacing better? It’s always an interesting topic, whether you grow corn, soybeans, pulses, cereals or oilseeds such as canola and flax.
During the past two decades, the trend in most crops has been toward wider spacing. However, a counter trend has recently emerged with excellent corn yields on narrower row spacing; down to 10-inch spacings.
Stine Seeds in Iowa has recorded significant yield increases in whole-field trials the past few years. Harry Stine says some of his seed customers have seen a 30 percent yield bump when planting 50,000 seeds per acre on a 10-inch row spacing.
In Manitoba, the Blumengart Colony harvested 284 bushels of corn with a 52-pound bu. weight. They planted 45,000 seeds per acre, also on a 10-inch row spacing.
To meet the growing demand for corn on 20-inch row spacing, Kinze recently introduced their new model 4700 planter, with 20-inch spacing for growers who want narrow row spacing. Kinze says there are three significant changes to previous models:
- Standard equipment on the 4700 includes the Blue Vantage display, Blue Drive electric drive and True Depth active hydraulic down force.
- The three-section frame has 15 degrees of tool bar flex up and down for good ground contact.
- The 600-gallon liquid fertilizer capacity is optional.
“The 4700 brings technological innovations and enhancements to the narrow row market,” says Kinze president Susanne Veatch.
“Dealers and customers have been asking for a new narrow machine. The 4700 brings the reliability and durability farmers are accustomed to from Kinze.”
The 4700 planter will be available for the 2020 planting season in a 36-row 20-inch configuration. In the future, it will be offered in 24-row 20-inch and 24-row 30-inch configurations.
Some farmers like to have row markers as a backup. If their GPS goes down, or auto steer goes out, they can still continue to plant using the row markers.
