The effects of Rhizobium inoculation, lime and
molybdenum supply on yield and yield components of
Phaseolus vulgaris L. were investigated in a split-split
plot design in the greenhouse and field experiment. Results
showed that Rhizobium application significantly
improved the
number
of pods per plant, number of seeds per plant, 100-seed
weight and seed yield. Furthermore, compared with the zero
treatment control, molybdenum supply significantly increased
the number of pods per plant, number of seeds per plant,
100-seed weight and seed yield. In general, these parameters
were significantly increased with molybdenum supplied at the
highest rate of 12 g per kg of seed. With regard to lime,
significant increases were recorded in number of seeds per
pod and seed yield. Application of lime at the highest rate
(3 t lime per ha) was significantly superior to the control
and 2 t of lime per ha. The combination of these supplies at
different levels resulted in significant interactions in
some parameters and thus indicating need for these inputs in
the study area.
Key words:
Beans, number of pods per plant, number of seeds per pod,
100-seed weight, interaction.
