Integrated fruit production (IFP) offers an alternative to the chemically intensive, conventional pear production system. In 1994, we began a 4-year project supported by the Hood River Grower Shipper Association (HRGSA) together with Oregon's Center for Applied Agricultural Research (CAAR) to demonstrate to the industry how to bring about changes in orchard management practices, particularly as...

Dallot, S., Gottwald, T., Labonne, G., and Quiot, J.-B. 2004. Factors affecting the spread of Plum pox virus strain M in peach orchards subjected to roguing in France. Phytopathology 94:1390-1398. We evaluated the impact of roguing on the spread and persistence of the aggressive Plum pox virus strain M (PPV-M) in 19 peach orchard blocks in Southern France. During a 7to 10-year period, orchards ...

In Spain, water use in agriculture is expected to become limited by resources the future. It pertinent study effect of decreased irrigation on presence pests, plant damage, and arthropod communities a super-intensive olive orchard examined from 2017 2019. Arthropods were studied with visual vacuum sampling methods two treatments (T1—control T2—Regulated Deficit Irrigation (RDI)). Univariate ana...

In 1918 Pólya formulated the following problem: “How thick must the trunks of the trees in a regularly spaced circular orchard grow if they are to block completely the view from the center?”(Pólya and Szegő [2]). We study a more general orchard model, namely any domain that is compact and convex, and find an expression for the minimal radius of the trees. As examples, solutions for rhombus-shap...

The physiological and psychological relaxation effects of viewing a kiwifruit (Actinidia deliciosa 'Hayward') orchard landscape were investigated. Seventeen Japanese adult females (46.1 ± 8.2 years) viewed a kiwifruit orchard landscape or a building site (control) for 10 min. The heart rate variability and heart rate were determined. The modified semantic differential method and the short-form ...

We describe a natural way to plant cherryand plumtrees at prescribed generic locations in an orchard.

We describe and prove uniqueness of a natural homomorphism (called the Orchard morphism) between some groups associated to finite sets.
