Intercropping cereals with grain legumes enhances slightly the economic worth of wheat for bread-making but have no or negative effect

Effects of intercropping on cereal quality are not always expressed in effects on economic worth due to the use of threshold levels when marketing grain, and also the need for achievement of multiple targets for certain end-uses. The effects of intercropping on the quality of wheat for breadmaking are generally positive but estimates of improved worth of 2 to 5%, when the maximum premium for breadmaking wheat is 22.5% over the feed wheat price, need to be balanced against cost penalties for admixture and/or effective separation of the cereal from the pulse.

The effects of intercropping with pea on the quality of barley for malting are likely to be negative, either due to the costs of admixture and/or cleaning (not quantified) or due to increases in grain nitrogen concentration (reducing worth/t by 1-2% when the maximum premium for malting barley is 26.5% over the feed barley price). Not all the effects of intercropping on grain quality are assessed at the point of sale of grain. These effects may be more relevant to organic farmers using grain on farm, or to organic farmers with a financial interest in the processing chain.
