Crown Rust Resistance

As many producers know, Crown rust (Puccinia coronata) can greatly reduce forage production. Ed diploid annual ryegrass has been specifically bred to be resistant to Crown rust. Data from Texas trials confirms that the breeders succeeded. In Overton and Beaumont Texas, Ed scored better in crown rust resistance 50 times against other varieties, and was equal to other varieties 26 times! Only 5 varieties had a higher resistance score, and that was in one location. All 5 varieties had equal resistance scores in the other location.

Feed Value

Ed is "ed-ible"! It will provide ample nutrition for dairy, beef, or any other livestock.

Recomendaciones de siembra

Prior to Planting

For optimal performance, prior to planting, obtain a soil test. Amend soil according to recommendations and fertilize after planting according to recommendations and use. Optimal pH Range is 6.0–7.0.

How to Plant

Ed can be drilled or broadcast into either a prepared seedbed or an existing sod bed. For prepared seedbed, lightly disc and pack well. For existing sod bed, reduce existing sod height as much as possible.

Fertilization

Application of fertilizer (following soil test recommendations) throughout the growing season and/or use of legumes will provide maximum forage tonnage and root growth.

Densidad de Siembra

New Pastures
25–35 lbs/ac
Overseeding
10–15 lbs/ac

Fechas de Siembra

Ed can be planted throughout the year. However, maximum utilization will be obtained by planting in the fall as soon as adequate moisture is available. If planted at other times of the year, performance will be limited.
