ABSTRACT: Bean crop producers from the Brazilian Cerrado region have only one technology adjusted for the irrigation management: which consist in the measurement of soil-water tension through the use of tensiometers. Although this methodology has high potential of use, it has not been widely adopted by the producers due to problems in instrumentation maintenance. Thus, the utilization of models to estimate evapotranspiration estimate has shown to be applicable to the Cerrado region. So, this paper aims to evaluate the performance of the Christiansen-Hargreaves model to estimate evapotranspiration of black bean crop in the dry season of the brazilian Cerrado region. It also aims to provide an the adjusted model to estimate evapotranspiration which permit an efficient management for the agricultural irrigated system of the Cerrado region. The the black bean evapotranspiration was measured with the use of a weighing lysimeter. The experiment was carried in the Brazilian Agricultural Research Corporation (Embrapa Cerrados), located in Planaltina, DF, Brazil. When calculated with crop coefficient determined in the research and tested with adjusted energetic term (S0=0.5), the Christiansen-Hargreaves model presented an excellent performance and may be used in irrigation management of black bean crop. |
