Abstract: Horizontal and vertical distribution of roots of one year old Leucaena eleucocephala. Gliri- cidia septum and Senna siamea plants on field plots were studied using the skeleton (dry exca-vation) method. Root systems of the three speĀ¬cies generally consisted of a strong downward growing tap root with laterals originating from the mam root axis. In Leucaena and Senna. roots developed faster than shoots, and at the end of 9 weeks after sowing, mean root length shool height ratios were 1.41 and 1.46 respec-tively. Total root biomass ranked in the order Senna > Gliricidia . Leucaena. The bulk (an average of about 81%) of the root biomass of all the three species are found in the top 15cm depth of the profile. Horizontal root spread var-ied from 98.2cm in Leucaena to 104.7cm in Senna. Active nodules were observed on the roots of Leucaena and Gliricidia but not Senna. The study concludes that the three species are likely to compete with agricultural crops for wa-ter and nutrients when grown together.
