Research on corn-soybean strip-cropping has demonstrated higher yields for edge rows of corn and lower yield for edge rows of soybeans. Nitrogen application to strip-cropped corn is often done with the planter or as 28% UAN, so that nitrogen is applied uniformly on each row of corn. The objective of the study was to evaluate if ESN, a 44% polymer coated controlled release nitrogen, would improve corn yield in a narrow (6-row) strip-cropping system. ESN was applied with a centrifugal spreader using a double pass procedure. Excessive June and July rainfall in 2004 resulted in denitrification losses of 28% UAN while ESN proved efficiency with a nearly 20 increase in yield. Randomly selected, hand harvested sections of all rows provided an estimated yield an average 30% higher than combine harvested yield. Edge rows yielded 10% higher than 4 middle rows for ESN and 11% higher for 28% UAN.
