Abstract
The on-farm average yield of soybean (Glycine max) and beans (Phaseolus vulgaris) are 1t/ha and 0.8t/ha respectively. This is nearly a third of the potential yield, which is attributed to a number of factors including poor nodulation with the native rhizobia available in the soil. This study was done to assess the yield advantage for inoculation of selected improved soybean and bean varieties with Bradyrhizobium japonicum and Rhizobium leguminosarum bv phaseoli respectively, on-station in lira and at five on-farm sites for two seasons. The study sites were located in the districts of Agago, Omoro, Kitgum, Amuru and Lamwo. The mother baby trial methodology was used to conduct participatory adaptive research. A randomized complete Block design was used for on-station trials. The trials included evaluating response of three improved inoculated and uninnoculated soybean and bean varieties in each commodity against a local check. Results showed significant differences (p < 0.05) for both inoculated improved soybean and bean varieties. Inoculation of improved bean varieties significantly (p < 0.05) increased nodule numbers per plant, but was not significant for number of pods per plant. Also inoculation of improved soybean varieties significantly increased nodule numbers per plant, but was insignificant for number of pods per plant. Grain yield was also significantly (p < 0.05) higher in inoculated plots as compared to un-inoculated plots. Inoculation significantly increased yield in selected improved varieties in soybean and beans on average by 22.3% and 15%, respectively. In soybean MAKSOY 1N, MAKSOY 5N, MAKSOY 3N and LOCAL varieties were respectively improved by 14.13%, 23.33%, 64.40% and 42.8% compared to the non-inoculated controls. In beans NARO BEAN1, NARO BEAN2, NABE4 and LOCAL were respectively improved by 19.71%, 14.50%, 7.84% and 16.27% compared to the non-inoculated controls. It can be concluded that MAK-BIO-FIXER inoculum containing Bradyrhizobium japonicum and Rhizobium leguminosarum bv phaseoli as an efficient approach for improving the nodulation process and increasing grain legume yield for selected improved varieties in soybean and beans respectively. Therefore, the use of these inoculum to enhance yield in these varieties can be recommended.
