Leucaena leucocephala planted in three different soil samples was subjected to three different watering treatments. Though the rates of growth of the seedlings, their root lengths and the number of lateral roots produced improved with the frequency of watering, Statistical analyses at 5% level revealed that the different watering treatments had no significant effects on these growth parameters in different soil samples. Both the soil type and the frequency of watering affected the number of nodules. The dry weight of nodules was affected by soil type but the soil type and the frequency of watering did not significantly affect the dry shoot and root weights.
