P concentration over the control. The combination of VC + CR + B was at
par with VC + CR and FYM + CR + B but significantly superior to VC and
FYM + CR combinations. This is in conformity with the result obtained
by applying seaweed extract as a biostimulant in organic farming of green
gram (Zodape et al. 2010).

6.3.4 NPK UPTAKE BY GRAIN AND STOVER
In both years, FYM and VC had no significant effect on nitrogen uptake
over the control, whereas other combinations of organic manures and bio-
fertilizers resulted in significantly (p = 0.05) higher nitrogen uptake by
mung bean grain than the control (Table 5). In 2007 and 2008, FYM had
no significant effect on nitrogen uptake by mung bean stover over the
