This study was conducted to determine the potential evapotranspiration
(PET) of maize, the crop coefficient (Kc)
under full water requirement as well as the cause of decrease in
maize yield. It was determined that the seasonal PET of maize
is about 486.6 mm. The Kc under full water supply was found
to be: 0.11, 0.35, 1.51 and 0.34 for initial, development, midseason
and the late season stages respectively. The study also
revealed that maintenance of sufficient moisture need of maize
has a significant effect on growth, development and fruiting of
the crop.
