The objective of this study was to define the soil available water depletion (SAWD) in avocado, in order to use it as a criterion for irrigation programs in soils of fine texture and low aeration capacity. To determine appropriately the fraction of soil SAWD we performed three independent trials: Trial 1: We evaluated two treatments: T1, irrigation...

Avocado trees evolved in Andisoils, which are considered the optimum type of soils for tree growth due to their physical properties; mainly low bulk density (0.5 - 0.8 g cm-3) and high macro porosity (∼ 46%). In Chile, avocado orchards are mostly located in fine textured soils, with bulk densities between 1.3 and 1.5 g cm-3 and macro porosities clo...

Se realizó una investigación durante la temporada 2003/2004 en un huerto de paltos (Persea americana Mill.) cv. Hass, sobre portainjerto Mexicola, con el objeto de mejorar la metodología de medición del potencial hídrico xilemático medido a medio día (?xm), utilizando la técnica de la cámara de presión.. El huerto estaba localizado en la V Región (...

A research was developed during 2003 and 2004 at an avocado (Persea americana Mill.) orchard cv. Hass grafted on Mexicola rootstock. The orchard was located in the Vth Region of Chile (32°53' lat. S; 71°16' long. W). The orchard was under optimal water and nutritional condition. Several experiences were carried out to optimize midday stem water pot...
