Castor in 1985 was sown at the same spacing as
pearl millet/pigeonpea, but groundnut in 1987 was sown at 0.3 x 0.1 m
spacing. These spacings correspond to the recommended populations for
these crops in their sole systems, which means that in agroforestry 33% and
20% of the total area was lost to hedges with 3 m and 5.4 m alley spacings
respectively.
