6.3.2 GRAIN AND STOVER YIELDS
In terms of statistical significance (p = 0.05), FYM had no significant
effect on the grain yield of mung bean, whereas FYM + CR, VC + CR,
FYM + CR + B, and VC + CR + B, being at par, significantly increased
the grain yield of mung bean over the control, FYM, and VC alone in the
first year and over the control and FYM alone in the second year (Table 3).
Weather conditions during the second year of study were more favorable
than those of the first year. Mean monthly maximum and minimum tem-
peratures were relatively low during the second year as compared to the
first year. Total rainfall during the crop growth period of mung bean was
about five times more in the second year than in the first year. All these
favorable weather conditions resulted in higher yield during the second
year as compared to the first year. On the other hand, the superiority of
vermicompost was attributed to its slow and steady decomposition, which
probably released the nutrients slowly and in higher quantity compared
to other organic materials. Poonam et al. (2007) reported that seed in-
oculation with
Rhizobium
recorded an increase in yield by 12% to 16%.
