Kiwifruit is sensitive to water stresses (excessive and shortage) that easily occur when irrigation volumes are empirically determined. Appropriate calculation of water demand requires the knowledge of crop coefficient (Kc) and access to local evapotranspiration (ET0) data. This paper reports a 2-year research project on the adoption of specific Kc for the area of Cisterna (LT) as compared with local irrigation practice. Average seasonal irrigation volumes were 9.290 (microjet) and 6.906 m3 ha-1 (drip) per year, being about 25 and 20% respectively lower than the amounts empirically applied by local farmers. Irrigation criteria based on soil hydrological characteristics and effects on yield are discussed.

Abstract
Kiwifruit is sensitive to water stresses (excessive and shortage) that easily occur when irrigation volumes are empirically determined. Appropriate calculation of water demand requires the knowledge of crop coefficient (Kc) and access to local evapotranspiration (ET0) data. This paper reports a 2-year research project on the adoption of specific Kc for the area of Cisterna (LT) as compared with local irrigation practice. Average seasonal irrigation volumes were 9.290 (microjet) and 6.906 m3 ha-1 (drip) per year, being about 25 and 20% respectively lower than the amounts empirically applied by local farmers. Irrigation criteria based on soil hydrological characteristics and effects on yield are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
