A field experiment was conducted to assess the response to inoculation with rhizobia in a clay loam soil of the Nile Delta using faba bean (Vicia faba) for two successive winter seasons (1985/6 and 1986/7). Three selected strains of Rhizobium leguminosarum, TAL 634, NRC 65 and TAL 1400, were used singly or in combination as peat-based inocula in 1985/6 winter season. Strain TAL 1400 was replaced by strain F9 in the 1986/7 winter season. A significant seed yield response was obtained only with strain TAL 1400, in the 1985/6 season. In the 1986/7 season, no significant yield response was observed with any of the strains. The serotyping of nodules collected in the 1985/6 season showed that strain TAL 1400 was more competitive than either the indigenous rhizobia or the two inoculant strains. However, the majority of nodules formed in the 1986/7 season were formed from strains other than the inoculant ones.
在尼罗河三角洲的粘壤土上，用冬蚕豆（Vicia faba）进行了两年（1985/6 和 1986/7）连续冬季的接种根瘤菌田间试验。1985/6 年冬季，使用了 3 种选定的根瘤菌菌株（TAL 634、NRC 65 和 TAL 1400），单独或组合作为基于泥炭的接种物。1986/7 年冬季，菌株 F9 取代了菌株 TAL 1400。仅在 1985/6 年冬季，菌株 TAL 1400 获得了显著的种子产量响应。在 1986/7 年的季节中，没有观察到任何菌株的显著产量响应。1985/6 赛季收集的根瘤的血清型鉴定表明，菌株 TAL 1400 比土著根瘤菌或两种接种剂菌株更具竞争力。然而，1986/7 赛季形成的大多数根瘤是由接种剂以外的菌株形成的。
