and in the summer of 2002 in a 4 year old sweet cherry trees (Prunus
avium, variety Z-900) on Mazzard rootstocks in Bayramic-Canakkale
which is located in the west part of Turkey. Micro-sprinkler irrigation
was selected as the irrigation method. The trees were subjected to four
micro-sprinkler irrigation treatments (T-1, T-2, T-3 and T-4). The water
applied in treatment T-3 was considered sufficient to satisfy fully needs
of the crop (100% of ETc) and to allow good rooting and tree
growth. The water balance relationship was used in estimating ETc.
A total of 4 climatological methods were selected for estimating reference
crop evapotranspiration on a daily basis. Some of these methods are based
on combination theory and others are empirical methods based primarily
on solar radiation, temperature ans relative humidity. An attempt was
made in the current study to develop regional relationship between the
evapotranspiration measured and that estimated by the climatological methods,
such as FAO-Penman, Penman-Monteith, FAO-Radiation and FAO-Blaney-Criddle.
Performance of the climatological methods in estimating the ETo
values as compared to the measured values was evaluated on the basis of
root mean square error (RMSE). In 2001, the Penman-Monteith equation gave
the best results followed by FAO-Penman, FAO-Radiation and FAO-Blaney-Criddle.
In 2002, the Penman-Monteith and FAO-Blaney-Criddle equations gave same
results.]]>Abrisqueta, J.M., A.J. Ruiz and A. Franco,200150211227Allen, R.G. and W.O. Pruitt,1986112139155Allen, R.G., M.E. Jensen, J.L. Wright and R.D. Burman,198981650662Allen, R.G., M. Smith, L.S.
