Poor knowledge of water requirements limits irrigation water management to produce crops throughout the year. Crop
evapotranspiration and irrigation water requirement of cucumber were investigated theoretically at National Horticultural
Research Institute, Ibadan in southwestern Nigeria, using Blaney-Cridle equation. Seasonality comprised dry season
(December to March) and wet season (May to August). Climatic period comprised 10 and 5 years average. The results
indicated that crop evapotranspiration of cucumber did not differ between seasons and climatic periods. Mean seasonal
crop evapotranspiration (ET) were 482.17 mm and 482.8 mm for dry and wet seasons, respectively. Mean seasonal
irrigation water requirements was 369.36 mm in the dry season and zero in the wet season to enhance judicious use of
water resources to produce cucumber throughout the year in South-Western Nigeria. Applying 370 mm of irrigation water
seasonally is recommended for dry season cropping. Under rainfed cropping, supplementary irrigation is not necessary.
