Procedure For Hybrid Evaluation
Trials in 2004 consisted of four replicates with all hybrids located randomly in each replicate. Rows were hand-planted to a population of 75,000 plants per hectare (30,000 per acre). Weeds were controlled with herbicides and by hand. Fertilizer application followed common practice, using soil test information where available. Planting and harvest dates in 2004 are listed in the table.

About the Hybrid Performance Data
Yield of each hybrid is reported relative to the average of standard hybrids as indicated in the tables. Choice of standards does not represent endorsement by the Association.

Only hybrids submitted by companies for testing appear in this bulletin. Hybrids not included should not be considered undesirable.

In comparing hybrids, consider not only yield but also dry matter, grain content and lodging. Some hybrids have more digestible stover than others, but data are not yet available.

To convert dry matter yield from tonnes per hectare to tonnes per acre, multiply by 0.45. To express this as silage yield at 25% dry matter, multiply by 4.
