| Abstract: | The field phase of the present study was carried out at Bura, eastern Kenya. The introduced, drought resistantProsopis juliflora seedlings were watered at four different irrigation levels. 43 sample trees with 1772 root nodules were dug up and investigated. Several trees lacked viable root nodules especially in nonirrigated plots. Regression analysis indicated significant negative correlation between the mortality of the root nodules and the level of irrigation. Rhizobium strains, which were isolated from the sample trees, were capable of nodulating indigenousAcacia senegal. |
