Determination of evapotranspiration in young plantations of Cedr

Pozo Vázquez, Juan CarlosMy name is Juan Carlos Pozo Vazquez young entrepreneur; Forestry Engineer and MSc. in irrigation and drainage work at the Agricultural Engineering Research Institute, where I have served as a researcher, especially in forestry and the development of trees of high commercial value with irrigation systems.

Cedrela odorata. L. is an important species for timber production, accelerating the physiological growth of the species is an important element to manage this process and achieve better individuals in less time. The general objective of this work was to evaluate the evapotranspiration behavior of young plantations of Cedrela odorata L. under irrigation in different conditions of crop association with respect to rainfed plantations. Three treatments were established in an experimental area in the south of Havana, in a compacted Ferrallitic Red soil, involving established plantations of cedar under different conditions: T1- rainfed, T2- under drip irrigation and T3 intercropped with plantain under drip irrigation; soil moisture dynamics and foliar water potential were evaluated in selected plants and climatic variables and the number and dose of irrigations applied were recorded; these elements allowed to perform the water balance for the determination of crop evapotranspiration in each evaluated condition, using the mass balance.
