Introduction

Oats are commonly used as a feed crop but some varieties are suitable for higher value feed and food markets. The milling industry prefers higher protein varieties with plump kernels and lower hull content, while the horse industry prefers white hulled varieties.

Hulless oat varieties have excellent feed and food value but need to be stored drier than hulled varieties (<12% moisture) and do not flow as well in the bin. Yield values for hulless oat varieties are expressed after hull removal, which reduces the seed weight by 20-25% compared to hulled varieties.

Seeding Rate

The suggested rate of seeding is 85 to 100 Kg/Ha (76-90 lbs/A). While the seeding rate range have given equal yields, experience has shown that the higher rate provides more consistent yields and can overcome emergence stress, reduce the amount of secondary tillering, green kernels and produce earlier uniform maturity.

Central B.C. Oat Recommendations

Grain Maturity		Silage
Early	Medium
AC Juniper	AC Juniper	Calibre
Jasper	AC Mustang	Cascade
	AC Preakness	Derby
	AC Rebel	Jasper
	Calibre
	Cascade
	CDC Boyer
	Derby

Comments
Jasper is a good maturity match to medium maturing barley varieties.
Jasper is a good variety for use in swath grazing.
Cascade is a good maturity match to later maturing barley varieties.
