Evapotranspiration of rose cultivated in protected environment
The objective of this study was to determine the evapotranspiration and crop coefficient for the cut rose (cv. Carola) cultivated in protected environment and the coefficient of small tank installed inside the greenhouse during the period of one year. Five rows of plants were planted with spacing of 1.20 m between rows and 0.20 m between plants. Each line consisted of five plots with five plants per plot. Plants of the second and fourth rows and of the second and fourth plots were installed in four drainage lysimeters with dimensions of 1.20 x 1.20 x 0.80 m. The plants of the remaining plots were considered as border plants. A drip irrigation system was used. An automatic weather station was installed in the greenhouse and the data were collected and stored daily at an interval of one hour in a data-logger. The crop coefficient (Kc) showed mean values of 0.75 in the vegetative phase and 1.18 during the productive phase. The small pan (tank) coefficient (Ktr) was 0.72.
