ABSTRACT:
This study evaluates the productivity of cotton and sorghum in a shea-based
agroforestry system in northernBenin.
Tomboutou and Gounarou villages were respectively selected in the shea
parklands of Bembèrèkè and Kandi. Within each parkland and village, three
classes of tree crown diameter for shea trees (4 -8
m, 8 -10 mand i.e.,
average plant height and average biomass, dropped by 9.75% and 29.31%, respectively,
when planted under the crown. Cotton under the crown was 6.58% shorter compared
to plants outside the crown. Average bud production and average fresh biomass
for cotton plants was 13.06% and 36.06% less, respectively, when planted under
the crown of shea trees.
