Abstract
Replicated field experiments were conducted at the Kadawa
Irrigation Research Station (11o39 'N, 08o02 'E and 500m above sea
level) located in the Sudan savanna ecological zone of Nigeria
during the 1995/96 and 1996/97 dry seasons. The aim was to study
the effect of irrigation interval (5,10,15 and 20 day) and
phosphorus level (0,11 and 22kgP/ha) on growth and yield of three
chickpea (Cicer arietinum L.) varieties.
The results revealed that the three varieties significantly
differed in all of the growth parameters assessed with K850 having
an edge over the other two varieties although the differences were
not significant in both trials. The effect of irrigation was
inconsistent and less-marked. Stand count, numbers of branches per
plant and nodes per main branch were significantly influenced by
varying irrigation interval at 10 WAS in 1995/96 trial. Number of
leaves per plant was also significant at same period in 1996/97
trial. In both trials where the effect of irrigation was
significant, 10-day interval produced significantly higher values
of these parameters than other intervals due to the moderate
moisture regime. Phosphorus application did not significantly
affect growth parameters except crop dry weight and number of
leaves per plant at 8 WAS in 1996/97 trial.
In terms of yield and it attributes, variety K850 out- yielded
ICCV1 and C235 with respect to pod diameter, 100-seed weight and
also pod and grain yields in both trials. Shelling percentage
(1996/97) and number of seeds per pod (1995/96) were also
significantly influenced by variety. Different irrigation
treatments also resulted in varying significant effects on shelling
percentage, pod and grain yields in 1996/97 trials with 10-day
irrigation being superior to other intervals. However, none of the
yield parameters was significantly influenced by irrigation in
1995/96 trial. Also, phosphorus application at 11 kgP/ha resulted
in significantly higher shelling percentage, pod and grain yields
than other levels in 1996/97 trial. The effect of phosphorus on
other yield parameters was not significant in both trials.
Significant and positive correlations (P=0.01) were observed
between chickpea grain yield and plant height, number of branches
per plant and number of leaves per plant in 1995/96 trial; while
100-seed weight was significantly correlated with grain yield in
1996/97 trial only. Crop dry weight was significantly and
positively correlated (P = 0.01) with grain yield in both trials.
The study showed that K850 significantly outyielded C235 and
ICCV1 and 10-day irrigation appeared to be suitable for chickpea
production. Phosphorus fertilization at 11 kgP/ha was found to be
optimum for the growth and yield of the crop.
