Abstract:

The experiment
was conducted at the Institute of Agricultural Research and
Training, Obafemi Awolowo University, Moor Plantation,
Ibadan to determine the physiological qualities of cowpea
seeds produced in rain forest environment. Six varieties of
cowpea produced in two different locations were collected
from the Legume Improvement Programme of the Institute.
There were two experiments for this study. Electrolyte
leakage was determined using 3 replicates of 50 pre weighed
seeds with JENWAY 4510 digital electrical conductivity
meter, while sterilized river bed sand was used for standard
germination. All laboratory tests were conducted using the
complete randomized design (CRD).
 The results showed that variety and location had significant
(p<0.05-0.001) effects on germination percent (GCPT),
germination rate index (GRI) and seedling length.
Interaction between variety and location also had
significant (p<0.01) effects on GCPT, GRI and seedling
length. There were significant differences (p<0.05) among
the varieties with respect to the germination percent. GCPT
ranged from 66.67% in IT90k-227-2 to 92.67% in Ife BPC with
overall means of 78.33. GCPT was higher in cowpea seeds
produced in Ibadan than that produced in Ile-Ife. Number of
abnormal seedlings was not statistically different from one
another. Overall germination percent of the cowpea produced
in Ibadan was 88.44% and the percentage was lower in Ile-Ife.
Results also revealed that conductivity value was low in
seed produced in Ibadan which is an indication of high
quality seed over those produced in Ile-Ife. From the
results of this experiment it can be deduced, that high
quality seeds of cowpea can be produced in Ibadan and some
other parts of the State that fall under transition
environment.
 
Keywords: Cowpea, locations, electrolyte, leakage,
