Requerimientos hídricos del plátano dominico- hartón (Musa aab simmonds) en la región Santágueda (Palestina, Caldas)

The present study was developed at the farm ‘Montelindo’ of the University of Caldas in order to establish the hydric requirements of the plantain crop, based on the evapotranspiration calculated by Penman-Monteith method and the crop evapotranspiration according to the phonological stage of the plant. Plants of Dominico-Harton plantain were planted at 2m between plants and 3m between rows and the necessary agronomic practices were applied on time. At the beginning of the study the field capacity, the permanent wilting point and the usable water table were determined. Weekly, registers of climatic elements, plants growth and soil humidity tension with tensiometers located at 40, 48 and 45, 72 inches deep, were made. It was established that at the Santagueda region the Dominico-Harton plants, under appropriated culture conditions, require 1.141mm of water during a culture cycle; that water consumption increases as the development of the crop advances, being the flowering period the time of highest water consumption and also the most critical one in relation to water deficit. It was also found that plant height, leaves emission and pseudostem diameter have a direct relation with crop evapotranspiration.
