Production of Other Small Grain Species

Fertilizer recommendations for the other small grain species are provided in Tables 6-12 through 6-14. Insect control recommendations can be found in Extension Bulletin 545, Insect Pests of Field Crops.

Table 6-12: Recommended Nitrogen for Small Grains (Pounds Nitrogen Per Acre).

	Crop	Yield Goal (bu/ac)
	Barley	65	90	115
	Oats	90	120	150
Spring Application	(Spelt)	40**	75**	110**
Spring Application	(Barley)	55**	95**	135**
Spring Application	(Oats)	60**	90**	125**
Spring Application	(Rye)	60**	90**	60**

*Use short, stiff-strawed varieties.
**Reduce nitrogen rate by 40 pounds per acre on dark colored soils.
