Abstract
A field experiment was conducted at the Irrigation
Research Station, Ahmadu Bello University, Kadawa, during
the 1983/84 dry seaabn (September - May) to study the
Effect of Sowing Date and Moisture Streee at various growth
periods of maize. The treatments consisted of six sowing dates
starting from 23 September 1903 at monthly interval, ending
23 February, 1904 and three moisture stress treatments
consisting of unstressed (normal irrigation of 65mm depth of
water was applied at weekly interval), moisture stress at
flowering and moisture stress at grain development.
Earlier sowings i.e. September and October were superior
to late sowings. The maximum groin yield of 71G7 kg/ha was
produced when maize was sown on 23 October- Delaying sowing
until December, January and February reduced grain yield by
27.6, 33.0, 72.1 and 42.0%, especially compared to October
sowing.
