investigated a long-term effect of Leucaena leucocephala
a leguminous tree crop on the soil physico-chemical
properties and its possible effect on the fresh fruit bunch
(FFB) production of oil palm. L. leucocephala had a
highly significant (P<.01) effect on soil physico-chemical
properties than the control. The soil under Leucaena
leucocephala exhibited relatively high mean weight
diameter, water retention, total soil available N, available
P and Exchangeable cation, than the control, and thus
enhanced fresh fruit bunch (FFB) production. Mean fresh
fruit bunch yield, over a three year period, was
significantly higher (P<0.05), with FFB yields of
10.93 tons / ha in plots with L. leucocephala as
against 6.8 tons / ha in the control plots.
