Results on holed and unholed seeds, germination test
and weight loss were significantly different at p<0.05.
Fewer seeds were holed when treated with 0.3g of the
powder and was significantly different from the
untreated seeds. The result of germination test showed
that oloyin cowpea treated with the powder
germinated well but the untreated seeds had
significantly higher number of geminated seeds (Table
5). Weight loss was significantly reduced in treated
seeds while highest value was recorded from the
untreated seeds and was significantly different at
p<0.05. In Table 6 similar patterns was observed for
all the measured parameters on ife-brown cowpea as
in the Table 5. However, the result on the germination
test revealed a reduced germination for the seeds
treated with the powder at the rates of 0.2g and 0.3g.
Similarly highest number of seeds germinated from
the untreated seeds and was significant (p<0.05) from
the others except for the seeds treated with 0.05g of
the hyptis powder.
