Abstract
Both field and green house experiments were intended to investigate and evaluate the outcome of
rhizobial inoculation supplemented with P and K on climbing beans production in northern Tan zania. The results obtained indicated that, inoculation using Rhizobium inoculants supplemented
with fertilizers significantly (p ≤ 0.001) improved both vegetative and yield parameters of climb ing beans varieties compared with control treatment. The economic analysis in rhizobium alone
revealed a profit of US$ 2350 compared with control treatment with US$ 1558 profit, which was
finally reflected in higher percentage increase over control and higher marginal rate of return
(MRR). Thus, the use of Rhizobium inoculants supplemented with P and K increased climbing
beans yield and the economic analysis performed based on total revenue and variable costs re flected an improvement in economic well being of a small hold farmer of northern Tanzania
