Lupins wheat benefit

LUPINS produce 25% more free nitrogen than clover and 28% more than peas or beans.

That suggests yield benefit to following wheat will exceed the 1.5t/ha (12cwt/acre) expected with those other breaks, says Gorham and Bateson.

The firms spring-sown, narrow-leaved lupins (Angustifolius species) typically yield 3.5-4t/ha and command a £20-30/t premium over peas and beans, says Tony Rose. Including protein area aid that should give a gross margin of £500/ha (£200/acre).

"They can be sown from early March to mid-April, once soil temperatures are 4C or above," he says. &#42
