Conjunctive use of
Rhizobium
with PSB and plant growth-promoting rhi-
zobacteria revealed synergistic effect on the symbiotic parameters and
grain yield of mung bean. In both years, stover yield of mung bean was
not significantly affected by FYM and VC and FYM + CR, whereas other
combinations of organic manures and biofertilizers significantly increased
the stover yield of mung bean over the control. There was no significant
difference between different combinations of organic manures and biofer-
tilizers in both years of study. The findings are in corroboration with those
reported by John De Britto and Sorna Girija (2006).
6.3.3 NPK CONCENTRATION
In 2007 as well as in 2008, all combinations of organic manures and bio-
fertilizers significantly increased nitrogen concentration in mung bean
grain over the control (Table 4). All the combinations of organic manures
and biofertilizers were at par in respect of N concentration in mung bean
grain in both years of study. In both years, FYM had no significant effect
on N concentration in mung bean stover, whereas all other combinations
of organic manures and biofertilizers significantly increased nitrogen con-
centration in mung bean stover over the control. There was no significant
difference between the different combinations of organic manures and
biofertilizers, and all the combinations, except FYM, significantly in-
creased phosphorus concentration in mung bean grain over the control
in both years. In both years, phosphorus concentration of mung bean was
not significantly affected by FYM, VC, and FYM + CR, whereas other
combinations of organic manures and biofertilizers significantly increased
P concentration of stover over the control. There was no significant differ-
ence between different combinations of organic manures and biofertilizers
in both years of study. In both years, the combinations of FYM, VC, FYM
+ CR, and VC + CR were at par and significantly increased K concentra-
tion in mung bean over the control. Similarly, FYM + CR + B and VC
+ CR + B, being at par, significantly increased K concentration in mung
bean grain over FYM. In 2007 as well as in 2008, FYM had no significant
effect on potassium concentration in mung bean stover, whereas VC, FYM
+ CR, VC + CR, and FYM + CR + B, being at par, significantly increased
