Abstract

Subsurface drip irrigation is increasing in South Australia. Efficient irrigation management of this system requires a reasonable estimation of crop evapotranspiration (ETc). A common approach for estimating ETc is to multiply a crop coefficient (Kc) by a reference evapotranspiration (ET0).A monitoring program was developed to assess a typical subsurface dripirrigated processing tomato field in the North Adelaide Plains, South Australia,emphasising estimation of the daily dual Kc and ETc using different approaches and comparing results with the applied water. The results indicated that irrigationscheduling based on weather, plant andsoil observation experiences coupled witha simple monitoring program can providea successful field management strategy.This is particularly useful for remote areaswhere access to new technologies andmonitoring tools is limited.
