Substantial hectarages of land are planted to wheat ( Triticum aestivum L.) every year in northern Nigeria. However, information on scheduling of irrigation for wheat grown in this part of the world is scanty. Field experiments were, therefore, conducted from 1982 to 1984 to study the response of wheat to seasonal and individual irrigations. There were three seasonal irrigations: (i) 300 mm, (ii) 450 mm, and (iii) 600 mm. Each seasonal irrigation was divided into three smaller individual irrigations (30,45, and 60 mm), which were applied at different frequencies. The experimental field soil has a water table that fluctuated between 85‐ and 115‐cm depths during the 1982–1983 and 1983–1984 growing seasons. Dry matter accumulation, plant height, and grain and straw yields were not significantly affected by the depth of seasonal irrigation. However, application of 30 and 45 mm water per irrigation gave higher grain yields than 60 mm. Wheat produced 5 to 6 Mg ha −1 grain when irrigated with 30 mm of irrigation water at 7‐day intervals.
