Sustainable irrigation in fruit trees

Irrigation of Fruit Trees and Vines

The impacts of three different water stresstiming patterns for three levels of seasonal applied water on production were evaluated in mature almond trees [Prunus dulcis (Mill.) Webb cv. Nonpareil] grown under high-evaporative demand conditions in the southern San Joaquin Valley of California. The stress timing patterns involved biasing water deficits to the pre-harvest or postharvest periods in...

Pear fruit growth under regulated de®cit irrigation in container-grown trees

The effect of regulated de®cit irrigation (RDI) on fruit growth was studied for pear trees (Pyrus communis L. `Barlett') grown in 120 l isolated containers. Two irrigation treatments were applied in consecutive seasons (1996 and 1997) but on different trees each year. The Control treatment was watered to non-stress conditions using stem water potential (Cstem) and Penman ETo as a guide for the ...

Effects of regulated deficit irrigation on physiology and fruit quality in apricot trees

The effects of regulated deficit irrigation (RDI) were studied on 9 year-old apricot-trees (Prunus armeniaca L. cv. ‘Búlida’) grafted on ‘Real Fino’ rootstock. Two irrigation treatments were established. The first, a control treatment, was irrigated to fully satisfy the crop water requirements (100% ETc) and the second, a RDI treatment, was subject to water shortage during the non-critical peri...

Sustainable Trees for Sustainable Cities

The idea of sustainable cities is linked to an older concept of sustainable plant communities. The theoretical basis for both is a closed system where everything is continuously recycled. Natural resources are renewed rather than depleted. In undisturbed natural areas a kind of sustainability is achieved through the natural cycles of the biosphere. However, this kind of sustainability for trees...
