Source and Time of Application of Nitrogen for Rye Forage¹

ABSTRACT

The effectiveness of five sources of N for rye forage production was compared in a 3-year field experiment on Cecil sandy loam. Each source of N was applied at the rate of 120 pounds per acre by two methods: (1) All N at planting, and (2) one-half N at planting and one-half February 15.

Ammonium nitrate, sodium nitrate, urea, and ammonium sulfate were found to be equally effective as sources of N for rye forage. Calcium cyanamid was an inferior source of N producing approximately 400 pounds per acre less forage than the other fertilizers.

Applying the N in split application resulted in approximately 300 pounds per acre more forage than applying all the N at planting. All sources of N responded similarly to split-application. Applying all the N at planting increased the forage production at the first 2 clippings an average of only 100 pounds per acre for all N sources as compared to the split application.
