| description | Rhizobium strains isolated from Leucaena leucocephala. Sesbania rostrata, S. grandiflora, S. punctata, Tephrosia vogelii. Acacia albida and Vigna unguiculata growing in Nigerian soils were characterized and tested for their ability to nodulate and fix atmospheric nitrogen with L. leucocephala. Isolates from L. leucocephala, S. rostrata. S. grandiflora and S. punctata were fast-growing and acid producers whereas those from A. albida, T. vogelii and V. unguiculata were slow-growing and alkali producers. Some of these isolates grew in the presence of 500 μg streptomycin ml−1. The effectivity of the rhizobia isolates on L. leucocephala was tested in Leonard jars. Isolates from all plant species except those from S. grandiflora and V. unguiculata nodulated L. leucocephala but a wide range of effectiveness was observed. Based on this experiment the ten most promising rhizobia were screened for effectiveness in potted soils collected at IITA, Ibadan (transition forest savanna), and at Fashola (savanna, 70 km north of IITA). Establishment of L. leucocephala was poor in soils without previous history of L. leucocephala cultivation due to the presence of only few native leucaena rhizobia (< 1000 g−1 soil). Rhizobium isolates IRc 1045 and IRc 1050 obtained from L. leucocephala grown at Fashola and IITA were found to be the most effective rhizobia on this host. In addition to their effectiveness and competitiveness they survived well in the field 1 year after their establishment. |
