AkinyemijuO.A. 1200771Field studies were conducted at Ile-Ife between 2000 and 2002 to compare the nodulation, chlorophyll content and nitrogen accumulation of Leucaena leucocephala (Lam) de Wit cv. 28 and Gliricidia sepium (Jacq.) Walp cv. ILG50 at the early stages of growth (2-16 Months after Planting) (MAP) to evaluate the two species under no external input system routinely practiced by farmers. A Randomized Complete Block Design in three replications with species as the single factor was used. The number of nodules produced by G. sepium (96.0/plant) was higher than in L. leucocephala (44.0/plant). At 12 and 16 MAP, leaf total chlorophyll content of G. sepium was 6.12 μM g-1 and significantly (p<0.05) higher than 4.12 μM g-1 produced by L. leucocephala. However, chlorophyll stability index of L. leucocephala was greater significantly (p<0.05) than that of G. sepium (94.5 vs 69.7%). At final sampling (16 MAP), G. sepium partitioned 48.3 and 51.7% of its total nitrogen content to below ground and above ground parts, respectively. In contrast, L. leucocephala partitioned 35.3 and 64.7% of its total nitrogen content into below ground and above ground parts respectively. Significantly (p<0.05) higher nitrogen accumulation occurred in G. sepium (54.20 kg/plant) than in L. leucocephala (42.80 kg/plant) at 16 MAP. It is concluded from the study that productivity of G. sepium as hedge species is higher than L. leucocephala in terms of nodulation, chlorophyll content and nitrogen yield under no-external input field conditions.]]>Awotoye, O.O., M.O.
