Over the last 10 years Canterbury farmers have started to diversify their pasture base in order to optimise their stock production. While ryegrass is still the base grass of our pastoral system, it is unsuited to many sites where pasture must generate high stock growth rates despite seasonally low rainfall, high soil temperatures and pasture pest challenge. On such sites, pastures based on cocksfoot, (Dactylis glomerata L.), phalaris (Phalaris aquatica L . ) and tall fescue (Festuca arundinacea Schreb.) or prairie grass (Bromus willdenowii Kunth, cv. 'Grasslands Matua') or lucerne (Medicago sativa) or chicory (Cichorium intybus L.) have lifted net farming returns.
