Short term ryegrass yield comparison and economics
Over many variable seasons, later maturing proprietary ryegrasses are more profitable to grow than Tetila types under longer growing seasons as they grow substantially more feed and utilise spring rainfall to produce better quality feed than Tetila types
By choosing Mach 1® annual ryegrass over Tetila annual ryegrass, you pay $52/ha more for the seed for a return of $584/ha. You have recouped the cost of the seed eleven times over in any given season
Choosing Knight Italian ryegrass over Tetila annual ryegrass under the same system in year one, you can grow an extra 5,971kgDM/ha, increasing profitability by $1,493/ha with an increase in seed investment of only $95/ha
In these trials the first autumn/winter yield difference between Tetila and Mach 1® is negligible. Even in short to medium growing seasons, Mach 1® is a better option under many conditions as there is more quality leaf during hay and silage time compared to Tetila
When home grown is the cheapest source of feed, why not grow as much as you can
Mach 1 tetraploid annual ryegrass holds its quality later into the season than short season types. The photo below taken at Ballarat on the 29/12/11 demonstrates the high drymatter production of Mach 1 compared to Tetila.
