Haymaster® 7 is a premium quality, winter-active (7) lucerne with a dense, upright and dark green leafy growth habit. Haymaster 7 provides significant advantages in yield, quality, insect and pest resistance. It has fine stems and low stem fibre for highly digestible hay, fast regrowth and long stand life.
An ideal choice for growers seeking a winter-active, premium hay lucerne, which is also suitable for grazing. It combines exceptional forage quality, yield and persistence.
Haymaster® 7 was selected from elite test lines trialled in Australia. It is capable of auxiliary branching and has great visual appeal with its dark green, leafy and fine stemmed qualities. Haymaster® 7 retains its leaf and colour during bailing and has a high leaf to stem ratio for improved quality that translates into outstanding animal performance.

Lucerne requires deep, well-drained soils (sands to moderately heavy clays) with a slightly acid to alkaline pH. It is intolerant of high levels of exchangeable aluminium. PGG Wrightson Seeds recommend a crop rotation with a lucerne crop as this helps to lower the risk of root disease becoming a problem. This can be achieved by sowing a forage crop such as; winter sown Cooee® Oats/Southern Green Ryecorn or summer planting of sorghum/millet. This method also assists with weed suppression prior to final cultivation. Take a soil sample 6-8 months prior to planting as this will allow time for any soil pH or nutrient corrections to occur. It is important to have a well prepared seedbed, free of any weeds, prior to planting. We recommend the use of Superstrike™ coated seed which contains the correct rhizobia and insecticide to assist maximise seedling establishment and plant development. Weed infestation early in the life of lucerne stands can limit yield and hay quality. In general weed infestation is greater in the warmer months so any sowings in spring will require careful management including potential herbicide applications. Autumn sowing has less weed risk potential, however, herbicide applications may be necessary in certain circumstances.
Grazing management is important to maximise the life of the lucerne stand and to maintain the yield expected of the stand. In general, the grazing management of lucerne is a compromise between yield, quality and persistence. For new stands, aim to maximise establishment and pay attention to agronomy; don’t graze too early, limit grazing time and intensity. If you are seeking lucerne for animal or hay production, it is recommended that you schedule grazing to utilise feed when the plant’s secondary regrowth emerges. Use a number of small paddocks and bigger mobs to promote even rotational grazing. To maximise persistence, it is recommended that lucerne is rotationally grazed. Be careful not to graze lucerne excessively or for too long. Cattle bloat, nitrate poisoning and red gut can be caused by animals consuming too much lucerne. To avoid these issues do not graze immature or lush growth. It is recommended that dry roughage is provided to hungry stock prior to being introduced to lucerne.
