SF Emmerson
More energy when the heat is on
SF Emmerson is a new generation broad leaved tetraploid Italian ryegrass adapted to a wide range of environments. It has excellent establishment vigour and produces best in warm environments. It has good autumn-early winter production and a large spring flush, ideal for fodder conservation. Shown higher ME levels and lower NDF levels than diploid Italian ryegrass (except SF Indulgence DipQ) through the cool growing season offering more energy for conversion to meat or milk production. It has also shown excellent disease tolerance, in particular a low incidence of rust in humid environments. It has a very large seed, much larger than other tetraploids and we recommend sowing it at 35kg/ha
