Moira: Moira is an intermediate diploid perennial ryegrass. The Moira provides excellent spring growth.
 

Meiduno: This is a new variety for 2017. It offers the highest spring yield value for a late heading variety and is complemented by excellent sward quality. Meiduno is a late tetraploid.

 
Majestic: This is one of the most highly recommended late diploids recommended by the Department of Agriculture. Majestic delivers high total yields and spring growth. Majestic is a late diploid and has a heading date of June 2.
 
Oakpark: High PPI late diploid, high performing spring growth, bred at Teagasc Oakpark for Irish farmers, good digestibility, excellent sward density - (PPI 2019)
 
Fintona: An intermediate tetraploid variety, boosts very good spring and autumn growth and has a moderate Dry Matter Digestibility. The variety has a PPI index value of €178 and a May 22 heading date.
 
Barblanca (White clover): Perfect for silage, Barblanca is a large leaf variety of white clover with a very high total yield yet being a large leaf variety its grazing persistence scores are typically high. It offers very good Spring and Autumn yields.
 

What is the difference between Tetraploid and Diploid?

The main difference between diploid and tetraploid ryegrass is the number of chromosomes per cell. Diploid plants have two sets of chromosomes per cell whilst tetraploids have four. As a result Tetraploids have an increased cell size and have a higher ratio of cell contents (soluble carbohydrates) to cell wall (fibre). This means that tetraploids have a higher water content per cell and are more palatable. This leads to a high graze out of livestock.

However with less tillers tetraploids have a worse ground cover rate which can leave a gappy sward. This can be good for allowing clover to grow but can if are the only grass in a sward can leave the pasture exposed to poaching.  

Diploid in comparison have more tillers per plant meaning they will have better ground cover than tetraploids. Due to the lower water content per cell, diploids have a higher dry matter per kg of feed, meaning they cure and wilt easier when making hay or silage. They also offer more energy than tetraploid plants.

Both diploid and tetraploid plants will have similar protein levels. A mix of both is required regardless of what you are looking from your grass. However a higher percentage of tetraploid is better for grazing while a greater number of Diploids is more advisable for silage or hay meadows.

Animal performance benefits of Tetraploids.

Tetraploid ryegrasses offer several benefits in terms of animal performance. Due to the higher ratio of cell contents to cell wall, tetraploid plants offer several benefits for animal performance. One benefit is that it is more palatable to animals which improves intake and therefore leads to an increased animal production.  In addition tetraploid cells consist of easily available nutrients, such as sugars and starches necessary for more efficient rumen function. However it is important to remember that tetraploids  higher water content in the cells so when livestock are full from grazing the actual dry matter intake could be lower compared to that of diploids plants. A mix of tetraploid and diploid ryegrass could achieve a more balanced pasture, retaining a good level of dry matter production, an improved balance of quality feed and if used for silage will be more easily cured than a pure tetraploid pasture.

Grazing management.

It is important to monitor grazing pressures on tetraploid ryegrasses as they are sensitive to overgrazing because of their excellent palatability. If grazing occurs to a lower level than with diploid ryegrasses it may compromise persistence. Similar to diploid ryegrasses, tetraploid ryegrass require nitrogen applications to a similar level to ensure good growth after grazing.

Farm management benefits.

Tetraploid ryegrasses have higher establishment costs than diploids as the recommended sowing rate for tetraploids is higher due to the larger size of the seed (2-3 times heavier). If planting tetraploid ryegrass in a mix, the plants will allow up to 10% more clover in the pasture due to the reduced tiller density promoting an increased pasture quality.

 

What are the advantages of reseeding grass?

  • Reseeding grass is one of the highest paying investments that a livestock farmer can take advantage of.
  • Reseeding will deliver higher grass dry matter yields and higher quality of grass.
  • For every tonne of grass dry matter used there is and increase in profit of up to €160 for the farm.
  • Reseeding will increase your grass production by at least 10 % each year.
