Minority types offer alternative
WHILE perennial ryegrass makes up 95pc of all grass seed used in Ireland, the remaining 5pc consists of other ryegrass varieties and clover. have low sward densities and are susceptible to poaching under adverse conditions.
The Italian ryegrasses on this year’s Department of Agriculture Recommended List are Davinci (diploid), Fabio ( tetraploid) and Nabucco (tetraploid). higher than the intermediate and late groups of perennial ryegrass, but lower than the Italian ryegrasses. Hybrids tend to be more stemmy in summer than the intermediates and lates, but less stemmy than the Italians.
Four hybrid ryegrasses made it onto the Recommended List – AberEve (tetraploid), Alliance (tetraploid), Ligunda (diploid) and Pirol (diploid). abilities. They are classified according to leaf size into very large, large, medium and small leaved types. Very large and large leaved varieties are relatively tolerant to nitrogen fertiliser usage and compete well with companion grasses, making them suitable for silage production.
Medium leaved varieties are more suited to grazing but can also be used in silage mixes. Small leaved varieties are suitable only for grazing.
AberHerald, Alice, Aran, Avoca, Barblanca, Chieftain and Crusader are the recommended white clovers for this year.
