Abstract
In order to study the effects of moisture stress
imposed at different growth stages of wheat under various
seed rates, a field trial was conducted at Ahmadu Bello
University farm, Samaru, during the 1981/82 dry season with
three levels of seed rate (75, 100 and 150 kg ha-1 ) and
eight irrigation treatments consisting of normal irrigation
at every ten days and missing one or two irrigation(s) at
different growth stages.
Withholding irrigation at any growth stage before
anthesis reduced most of the growth characters. Missing
two consectutive irrigations during early stages from crown
root initiation (CRI) to jointing reduced most of the
yield-related characters. Missing two consecutive
irrigations at any stage reduced grain yield more than
missing one irrigation. The maximum yield reduction levels
of 13.3 and 65.4 percent were obtained when one irrigation
was missed at CRI and when two consecutive irrigations were
missed at jointing, respectively.
A seed rate of 100 kg ha-1 was found to be the optimum
for efficient water utilization in wheat
