8849. Henderson, C.W.L.. 1989. Lupin as a biological plough: evidence for and effects on wheat growth and yield.. Austral. J. Exp. Agric. 29:99-102.
Effect of sowing density of blue lupin on a following wheat crop was studied on a compacted earthy sand. Lupin density ranged from 25-200 plants/m2. High density plantings were better able to alleviate compaction, although total luaapin biomass declined as density increased. The benefit to wheat grain yield from less compaction was estimated to be 100 kg/ac. This is small compared to nitrogen and rotation benefits. Other benefits of high density include reduced erosion, less disease, and better weed control.
