Dwarf French beans and broad beans were grown at 0.25 m x 0.25 m for 2 years with a without cuttings of Populus RAP at spacings of 2.0 m x 0.5 m and 3.0 m x 0.5 m. The presence of beans lead to a greater height and diameter growth and greater total dry matter production per hectare of the Populus at both spacings after 2 years. Bean yield was reduced at the end of the second year by the presence of Populus; there was no effect at the end of the first year.
