Abstract
O trabalho trata da determinação do balanço hídrico de uma cultura de aveia forrageira de inverno (variedade São Carlos), cultivada sob condições de irrigação por aspersão, com o objetivo de obter informações básicas sobre seu comportamento sob regime de irrigação e de sua demanda hídrica para a região de São Carlos, SP. Os resultados de produtividade da cultura e dos balanços hídricos sob duas condições de disponibilidade hídrica no solo dão indicações de que o menor nível de disponibilidade de água no solo, correspondente a um potencial mátrico mínimo de -20Kpa à 20cm de profundidade, já é suficientemente satisfatório para garantir as máximas produtividades da cultura nas condições locais de solo e clima.
The aim of this experiment was to perform a water balance for a forrage oat winter crop (variety São Carlos) cultivated under sprinkler irrigation condition. The main objectives were to obtain basic information about the crop behavior under irrigation and the crop water requirement for the region of São Carlos, SP, Brazil. Crop yield and water balance results under two soil water availability levels gave indications that the lower level of soil water availability, indicated by a minimum matric potential of -20Kpa at the 20cm depth, is sufficient to provide conditions for highest yield under these soil and climate conditions.
