Abstract

Irrigation Water Requirement (IWR) under drip system was computed for a model date palm farm in the University of Maiduguri, 240 x 232 m in dimension, 10 m row to row and 8 m plant to plant totaling 750 trees in all. The peak and minimum values of ETo were 7.01 mm/day in June and 3.2 mm/day in December. The maximum crop evapotranspiration (ETc) of 217.31 mm/day computed was at developmental and mid growth stages which occurred in May. The peak value of water requirement considered as gross irrigation water requirement (Gir) was computed as 1,535,190 litres/year. The net irrigation water requirement (Nir) for the area under consideration at at 90 % application efficiency (Ea) was 1,381,671 litres/year. It is therefore recommended that the computed values be applied on experimental basis to validate the water requirements for field work.
