High production grazing
Seed Force is at the forefront of the resurgence of lucerne in Australia – today it’s the backbone of many high production grazing and cutting systems.
The activity level of a lucerne variety determines the number of cuts or grazings across the season.
High winter activity lucernes can be cut more often than more dormant types due to their more erect habit, faster regrowth and longer growing season. While they will produce more over the cool seasons they may not necessarily produce more than less winter active types over a full 12 month period.
Selection should also ensure good resistance to the major pests and diseases that may be a problem in your growing region.
Extra value from improved varieties
Seed Force’s trial database can be used to estimate the extra value delivered by newer improved varieties.
Yields are hundredised against control variety Aurora, which yielded mean 7.43t/ha dryland and 16.91t/ha irrigated. Variety yields have been estimated by multiplying Aurora yields by hundredised variety yields. Estimates on extra value per year can then be made for both dryland or irrigated conditions. This is based on average value of lucerne hay at $500 per tonne.
All the details can be found in the current Seed Force Lucerne Guide.
