Kheıry, Abdalla and Mohamed, Mysara Ahmed and Hassan, Rihab}, keywords={Class A pan,lyismeter,piche tube,evapotranspiration,greenhouse}, abstract={ Because of the large area utilized by a class A pan, alternative methods have been used to estimate reference evapotranspiration (Et o ) inside greenhouses. The objective of this work was to compare ET o estimated by different methods inside and outside a greenhouse. A class A pan (CAP i ), lyismeter (L i ) and piche tube (PT i ) were installed inside a greenhouse, and another class A pan (CAP o ) was installed outside. ET o estimates, obtained by CAP i , PT i , and L i were 81%, 56% and 86%of those estimated by CAP o , respectively. A simple linear regression showed positive coefficients (R = (0.96) for the L i and the CAP i ,R = (0.95) for the PT i and the CAP i , R = (0.88) for the CAP i and the CAP o , R = (0.96) for the L i and the CAP o , and R = (0.82) for the PT i and the CAP o ). ET o needs to be estimated inside greenhouses and it is possible to use lyismeter or piche tube to estimate the ET o inside the greenhouse. Equipment replacement would increase the available space inside the greenhouse. <o:p> </o:p> }, number={1}, publisher={Mevlüt AKÇURA}
