Inavale is relatively new to us, but we are trying it because it is one of the few varieties without 34% or more filler or coating. This is 100% seed. This medium to late-maturing leafy orchardgrass exhibits strong disease resistance. Its summer heat tolerance makes it a great choice for grazing or hay. This orchardgrass looks strong in test plots. EstablishmentInavale exhibits exceptional seedling vigor and establishes rapidly. In the transition zone, planting should occur in the late summer. Before planting, take a soil test and apply adequate phosphorus and potassium as needed. At planting, apply 35-40 pounds per acre of nitrogen to ensure good establishment. Inavale may be established via full cultivation, no-till, or broadcast seeding with cultipacking. Plant no deeper than 1/4 inch below the surface in a firm seedbed. ManagementOrchardgrass is classified as a bunchgrass. Careful stand management during the first year is essential for long-term productivity. Orchardgrass grows and spreads laterally by creating new shoots called tillers, which emanate from the base of the plant, forming an ever-wider bunch. To enable the production of a leafy dense stand, the height of the stand during the first year should ideally be maintained in the 4-12 inch range. This allows full sunlight penetration to the plant base, triggering the production of tillers needed for maximum plant growth and spread. Once the seedlings are firmly rooted, graze lightly by calves, or machine-mow before heavy use. This will promote further tillering and growth. Cold winter survival is enhanced by entering winter with the grass left at a short but still green height of 4-5 inches.
