Perennial ryegrass has come a long way since older varieties, such as Victorian perennial ryegrass.
New genetics are assisting growers in obtaining greater yields and improving quality.
Pasture Genetics Ansa Diploid Perennial Ryegrass, has been a proven performer in the Goulburn Valley of Victoria for almost five years now.
Pasture Genetics began trialling Ansa Diploid Perennial Ryegrass in 2011, to ensure it would meet the expectations of producers, and endure typical Australian climatic conditions.
Under irrigation and good management, many Ansa Diploid Perennial Ryegrass growers in the Valley have been seeing impressive results, not only with production, but also persistence.
Ansa Diploid Perennial Ryegrass was bred by the late Pedro Evans in New Zealand for DLF Seeds.
Pedro was based at the Department of Primary Industries in Hamilton, Victoria, for many years. He knew what the Australian market was looking for in a perennial ryegrass.
Ansa Diploid Perennial Ryegrass was bred for its prolific tiller density and outstanding dry matter production, particularly through winter and early spring.
Tiller density in a grass is very important to producers who are looking to graze pastures as it relates to the plants ability to recover from grazing and its dry matter production.
The higher the tiller density, the better a grass plant will tolerate adverse conditions, such as heavy grazing in wet conditions.
The management of grazing is also a contributing factor to its success, not only with Ansa Diploid Perennial Ryegrass but with all grasses. Over-grazing will reduce energy reserves in a ryegrass plant and will thin out the pasture quicker than expected, impacting the persistence and viability of the paddock.
Grazing your paddocks too hard will also slow plant recovery and extend the rotation length to grow the same amount of feed. Leaving 1,500 to 1,800 kilograms per hectare of residual dry matter on pastures post-grazing will assist in future production, persistence and recovery.
It can be difficult for producers to consistently manage pastures using correct management techniques, given seasonal conditions impact on feed production, feed availability and damage to pastures.
Ansa Diploid Perennial Ryegrass exhibits finer leaves and stems than tetraploid ryegrasses. Diploid ryegrasses tend to have greater tiller density, and are more tolerant than tetraploid grasses to grazing, especially when it comes to over-grazing.
Diploids are also more tolerant of water or “wet feet”, when compared to tetraploids. This is a bonus for Northern Victorian farmers, as the majority of pastures are flood irrigated for at least eight months of the year. This results in difficulties in achieving perfect pasture
Research that was extended by Dairy Australia last year, showed yield results for perennial ryegrasses and expressed them by Forage Value Index (FVI). These figures were based on total dry matter yield only. The high RVI of Ansa Diploid Perennial Ryegrass proves that it is a high performer – with year round performance and extensive winter production.
