Vellayani during 1998 to evaluate the effect of vermicompost enriched
with RP on P availability yield and quality of cowpea and the feasibility
of reducing the inorganic P. The variety used was Kanakamoni.
All the growth characters, yield and yield attributes studied were
significantly influenced by different treatments. Nodule number per plant,
weight of nodules per plant and root shoot ratio were maximum by the
application of enriched vermicompost. Yield attributes like number of
pods per plant, number of seeds per pod and hundred seed weight and
total grain yield were significantly increased by the application of
enriched vermicompost. Vermicompost primed with full RP or with half
RP produced no significant difference in grain yield. Thus the results
revealed that inorganic phosphoate for cowpea coufd be reduced to half•
of its recommended dose by priming vermicompost with RP.
Analysis of plant samples at harvest showed that maximum content
of macronutrients except Mg was recorded by enriched vermicompost.
It showed its superiority over other treatments for protein and P content
of grain. Enriched vermicompost also registered significant increase in
soil available N, P and K after the experiment.

Uptake of macronutrients was significantly influertced by different
treatments. Enriched vermicompost registered maximum mean value for
the uptake of all the macro nutrients. Priming of vermicompost with full
RP or with half RP produced no significant difference in uptake of any
macro or micronutrients.
Grain yield was positively and significantly correlated with the
growth characters. Yield and yield attributes showed positive and
significant correlation with nutrient uptake.
The study indicated the superiority of vermicompost enriched with
RP on yield and quality of cowpea. P recommendation for cowpea can
be reduced to half by priming vermicompost with RP.
