of organic manures and biofertilizers were not signifi cant in both years
of study. In 2007, FYM and VC had no signifi cant effect on K uptake by
mung bean, whereas FYM + CR, VC + CR, and FYM + CR + B, being
at par, signifi cantly increased potassium uptake by mung bean over the
control. The combination of VC + CR + B was at par with VC + CR and
FYM + CR + B but signifi cantly superior to FYM, VC, and FYM + CR.
In 2008, FYM and VC also had no signifi cant effect on K uptake by mung
bean, whereas other combinations of organic manures and biofertilizers
resulted signifi cantly higher K uptake than the control. There was no sig-
nifi cant difference between different combinations of organic manures and
biofertilizers during this year.

6.3.5 MICRONUTRIENTS CONCENTRATION IN GRAIN
In 2007, FYM, VC, and FYM + CR, being at par, significantly (p = 0.05)
increased Zn concentration of mung bean over the control (Table 8). Simi-
larly, VC + CR, FYM, CR + B, and VC + CR + B were at par and sig-
nificantly increased zinc concentration of mung bean grain over FYM. In
