Abstract
To explore the possibility of growing a good crop of
late sown maize with supplementary irrigation and suitable
weed control measures, on experiment was carried out at Kadawa,
Nigeria, in 1984. The irrigation treatments comprised of
irrigation at seven, 14 and 21 days intervals and at
attainment of severe moisture stress. The weed control
treatments comprised of hoe-weeding at three and six weeks
after sowing (w.a.s.), atrazine + eradicane (1.5 + 2.0kg
a.i./ha) and atrazine + metolachlor (1.25 + 1.25kg a.i./ha)
herbicide treatments. The herbicide treatments were followed
by supplementary hoe-weeding at six weeks after sowing.
Irrigation at seven, 14 and 21 days intervals
significantly increased the grain yield by 96, 58 and 60%,
respectively, over the treatment with severe moisture stress.
Parameters such as final plant height, days to maturity,
ear length, ear diameter, kernel depth and 1000-grain weight
of maize were all significantly superior under irrigated than
unirrigated condition.
There were no significant differences between the three
weed control treatments on weeds, yield and yield components.
They were equally effective.
In areas like Kadawa where water table is high, a good
crop of late sown maize can be grown with supplementary Irrigation
(325 to 39Qmntwater) at longer irrigation intervals of 14 or 21 days
