Abstract
Response of two maize cultivars TZBSR-W (120 days maturity) and
TZESR-W C90 days maturity) to time of basal fertilizer application
was investigated at the research farm of the Institute for
it
, Agricultural Research, Samaru during the 1990 wet season. NPK
fertilizer was basally applied at the rates of 60kg N/ha,
26.2 kg P/ha and 50kg K/ha. The two cultivars and four time of
basal fertilizer application - 0, 10, 20 and 30 days after
planting were laid out in a randomised complete block design
with four replications.
The study revealed that delaying basal fertilizer application to
TZBSR-W up to 20 days had no significant influence on grain yield.
delaying basal fertilizer application beyond 20 days significantly
reduced grain yeild (3998 kg/ha). The cultivar TZESR-W did not
respond significantly to time of basal fertilizer application
(3649 kg/ha, 3655 kg/ha 3667kg/ha and 3574 kg/ha for 0, 10, 20
and 30 days, respectively) The cultivar TZBSR-W outyielded
TZESR-W by 9.6%.
Plant dry matter results showed that plants basally fertilized
30 days after planting recorded significantly lower plant dry
matter at all times of sampling.
Delaying basal fertilizer application significantly decreased
plant height, ear height and leaf area index. Delaying basal
