To test different forage pea cultivars in mixtures with forage oat and barley for green feed production. To determine optimum proportion of forage pea in pea-barley or pea-oat mixture for green feed production. To determine animal preference, feed digestibility, and feed intake of pea-cereal mixtures. To determine forage pea N fixation rate in pea-cereal mixtures with or without N fertilizer. To conduct cost analysis of cereal-pea forage mixtures in comparison to barley and oat green feed production.
A two-year field experiment was conducted using forage pea cultivars ‘CDC Horizon’ and ‘40-10’ in mixtures with ‘CDC Maverick’ barley or ‘CDC Haymaker’ oat. Pea-cereal mixtures had better lodging resistance than the monoculture peas. Even though total amount of biological N fixation (BNF) was not high, a significant proportion of biological N fixation was transferred from pea to barley and oat in the mixtures. In general, the pea-barley mixtures and barley monoculture showed better economic return than the other mixtures and pea monocultures at the three study sites. The majority of pea-barley/pea-oat mixtures were sufficient to meet minimum crude protein requirements of beef cows at different gestation periods. Based on animal feeding trial, inclusion of pea hay within cereal hays will likely increase the nutrient density of the forage (increased starch and crude protein) and increase dry matter intake. However, beneficial effects on nutrient digestibility are dependent on the cereal grain type with positive effects for barley and negative effects for oat. Harvesting pea hay at the mid to late stages will maximize DM yield/ha (dry matter yield per hectare).
