ABSTRACT
Pot and field studies were carried out at the University o f Ghana, Legon, to evaluate
the effect of Bradyrhizobium japonicum inoculation and five rates of phosphorus
application on growth, nodulation and dry matter production o f some promiscuous
and non-promiscuous soybean cultivars in pots and finally the effect o f three rates of
phosphorus and inoculation on growth, nodulation, dry matter production and yield
of a promiscuous cultivar "Bengbie" in the field.
In the pot experiment, one non-promiscuous cultivar (Davis) and two promiscuous
cultivars (Bengbie and Anidaso) were inoculated with B. japonicum strain TAL 102
and also received 0, 8.9, 17.9, 26.8 and 35.7mg P/kg soil (equivalent to 0, 20, 40, 60
and 80kg P/ha.). Inoculation generally caused significant increases in nodulation,
shoot dry weight, shoot nitrogen (N) and shoot (P), but not root dry weight.
Phosphorus application on the average increased nodulation, root and shoot dry
weight and shoot N and P.
The non-promiscuous cultivar produced higher nodulation and shoot N than the
promiscuous cultivars on inoculation.
Interaction between inoculation and cultivar was significant for nodulation, root dry
weight and shoot N while phosphorus and cultivar interaction was significant for
shoot dry weight and shoot P.
In the field experiment, one promiscuous cultivar "Bengbie" was inoculated with B.
japonicum strain TAL 102 and given 0, 30 and 60 kg P/ha. Inoculation in the field
increased nodulation, root dry weight, shoot N and shoot P. This indicates that
promiscuous cultivars can benefit from inoculation. However, inoculation failed to
increase pod number and final grain yield
Phosphorus application up to 60kg/ha did not significantly increase nodulation,
shoot and root dry weight, shoot N and P, 100 - seed weight and final grain yield.
