The Effect of Intercropping Populus 'RAP' with Beans

Dwarf French beans and broad beans were grown at 0.25 m x 0.25m 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 presenceof beans lead to a greater height and diameter growth and greatertotal dry matter production per hectare of the Populus at bothspacings after 2 years. Bean yield was reduced at the end ofthe second year by the presence of Populus; there was no effectat the end of the first year.
