The soybean is an important source of protein and gaining popularity in Ghana due to a rising demand for its use the poultry industry. However, grain yield soybeans relatively low Upper West Region infertile soil climate change. This study evaluated root nodulation symbiotic effectiveness 31 rhizobial isolates obtained from nodules planted at Da Region, Ghana, as well measured photosynthetic activity plants grown under glasshouse conditions. further assessed tolerance different levels temperature, drought, salinity, pH laboratory also ability produce indole-3-acetic acid. An infrared gas analyser 15N 13C natural abundance techniques were used assess activity, N2 fixation, water-use efficiency, respectively. results showed that test induced greater rates higher stomatal conductance stimulated increased water loss via leaf transpiration plants. Isolates TUTGMGH9 TUTGMGH19 elicited much shoot δ13C host plant biomass, C accumulation, percent relative effectiveness, fixation Bradyrhizobium strain WB74 5 mM nitrate, which positive controls. Although isolate did not grow 40 °C, it growth 5% PEG-6000, NaCl, while producing moderate IAA. better utilisation these bioinoculants, their performance needs be field conditions ascertain competitiveness efficacy.
