Estimation of water requirements of early and late season maize in Umudike southeastern Nigeria, using Penmans equation
Journal of Soil Science and Environmental Management
The estimation of water requirements of early and late season maize was carried out based on 10 years meteorological data at Umudike, typical of the humid tropical zone using the Penman's equation. The results obtained showed that the seasonal crop evapotranspiration (ETo) value for early season maize (April -July) was 450.66 mm while that of late season (June -September) was 369.72 mm. The irrigation water requirement was zero for early and late season maize. Supplementary irrigation is notdoi:10.5897/jssem2014.0460 fatcat:fminw5webnejzg3ibejzurzpei
