Aims
To compare several field pea, vetch, canola, triticale, oat, barley and wheat varieties for dry matter production and feed value. A further trial was included to determine the optimal densities of field pea/oat mixtures.
Key messages
Oats can be included as a minor component (up to 25% on a denstiy basis) in peas with aroudn a 10% increase in yield compared to growing the crops separately.
Higher proportions of oats are too competitive with the peas and the pea yield is greatly reduced.
Spring sown fodder crops yield substantially less than autumn sown crops but they may be a viable option where waterlogging affects autumn sowings.
