Kidman NEA2 Perennial Ryegrass

Contact us

Perennial ryegrass (Lolium perenne) is the grass of choice for permanent pastures. It establishes rapidly, yields well, tolerates a range of management practices and has a high nutritive value.

Perennial Ryegrass

  • Early maturing (-9 days relative to Nui)
  • Low aftermath heading compared with comparator varieties in segment
  • NEA2 endophyte offers broad insect protection and animal safe ‘stagger free’ grazing
  • Excellent autumn, winter & early spring production
  • Leafy summer production, unlike Victorian & Kangaroo Valley ecotypes
  • Improved utilisation in spring when compared with Victorian SE perennial ryegrass

Kidman NEA2 is an early maturing densely tillered diploid perennial, suited to  sheep & beef grazing enterprises in 550mm/yr. + temperate regions. Kidman with  its early maturity and excellent autumn, winter and early spring growth will help to  fill critical feed gaps in many farming systems. Combined with a robust ‘safe’  novel endophyte in NEA2, Kidman is an all round performer for yield, quality  and persistence. 

Key benefits

  • The superior growth curve at critical times in late autumn, winter and early spring means reduced need for costly supplementary feed
  • The ability to respond to summer rainfall events, results in greater leafy summer production
  • Due to low ‘aftermath’ heading, the quality and utilisation of feed grown in spring is maximised with Kidman. This results in better liveweight performance and returns per hectare
  • The combination of NEA2 endophyte provides robust insect protection, aiding persistence, while offering a ‘safe’ grazing option free of issues like ryegrass staggers & heat stress
  • The superior seasonal forage production means greater cheap ‘home grown feed’, improving carrying capacity and profitability


Kidman performs well where other early maturing perennial ryegrasses, like Victorian and Kangaroo Valley varieties perform, but offers superior growth curves and production. It is ideally suited to temperate regions that exceed 550mm/yr. and where rainfall is more concentrated to autumn, winter and spring, however due to the background breeding of Kidman, it can also provide application in higher rainfall areas where summer production is required. This means it is a highly adaptable cultivar. Kidman is ideally suited to many sheep and beef grazing systems, both autumn and spring calving/lambing however does also have application into dryland dairy systems. An example of Kidman’s performance is evident in the Dairy Australia Forage Value Index1, where it is one of the highest performing cultivars. Kidman has been upgraded from AR1 to NEA2 to provide greater insect protection, and persistence, while still providing safe ‘stagger free’ grazing option.

Agronomy and management

Graze when seedlings resist pulling and tearing the leaves.  The best time is typically 8–10 weeks after sowing, but at earliest opportunity to allow light into the base of the pasture thus encouraging tiller and clover development. It also makes a good companion for most pasture legumes including white, strawberry, sub and annual clovers. Usually sow 80% grass by seed count, 20% clovers by seed count. It is best sown as the only grass species, due to out-competing other slow establishing species, however mixes with cocksfoot or other ryegrasses can offer benefits.

Sowing Rate

Sow from February - October, when moisture available.

  • 750mm+ / irrigation: 20-25kg/ha
  • 750mm - 600mm: 15-20kg/ha
  • <600mm: 10-15kg/ha
