Yield potential of reduced-branching lupins (Lupinus angustifolius) on sandy soils in a short season environment

Abstract

Experiments that compare the yield potential of reduced branching narrow-leafed lupins with that of the conventional branched types show that on sandy soils of low water-holding capacity in a short season environment, reduced-branching lupins have a higher yield potential than current cultivars. The yield potential of these new types appears to be maintained over a wide range of environmental yield levels. L. angustifolius was higher yielding than L. albus or L. cosentinii genotypes of similar maturity.
