Determining Optimum Nitrogen Rates for Irrigated Timothy Hay for Export

Very little work has been done on determining optimum nitrogen rates for Timothy hay.

IPNI-2015-USA-WA16

Background I am located in the center of irrigated timothy production for Washington State. Timothy hay is our largest grass hay commodity and we export it to Japan and other countries. We can produce 10 ton per acre in cuttings but most farmers use two cuttings and receive around 5 - 7 tons/acre. Very little work has been done on determining optimum nitrogen rates for this commodity. Read more

Interpretive Summary

2016

Timothy hay is the largest grass hay commodity exported to Japan and other countries from the Pacific Northwest. It is possible to produce 10 t hay/A in three cuttings, but most farmers use two cuttings and achieve 5 to 7 t/A. Very little work has been done on determining optimum nitrogen (N) rates for this cash crop.
