Table 2-7 Effect of Seeding Rates on Yields (5 yr. average)

For complex mixtures (meadow fescue, Canadian brome, ryegrass, timothy, Domestic ryegrass, red fescue, ladino clover, white Dutch clover, Lincoln brome, Wild shite clover, redtop, Wood's meadow fescue, Kentucky blue, wheat):

When the seeding rate is 12 lb/acre, the dry matter yield will be around 2.15 tons/acre.
When theseeding rate is 20 lb/acre, the dry matter yield will be around 2.10 tons/acre.
When the seeding rate is 35 lb/acre, the dry matter yield will be around 2.12 tons/acre.
for an average yield of 2.12 tons/acre.

For less complex mixtures (ladino clover, red clover, alsike clover, timothy, orchardgrass):

When the seeding rate is 12 lb/acre, the dry matter yield will be around 1.84 tons/acre.
When the seeding rate is 20 lb/acre, the dry matter yield will be around 1.92 tons/acre.
When the seeding rate is 35 lb/acre, the dry matter yield will be around 1.79 tons/acre.
for an average yield of 1.85 tons/acre.

For simple mixtures (red canary, birdsfoot trefoil):

When the seeding rate is 12 lb/acre, the dry matter yield will be around 3.26 tons/acre.
When the seeding rate is 20 lb/acre, the dry matter yield will be around 3.34 tons/acre.
When the seeding rate is 35 lb/acre, the dry matter yield will be around 3.43 tons/acre.
for an average yield of 3.34 tons/acre.
