The main characteristics of Narrow Orchard Systems (NOS) are (i) narrow canopies, with (ii) multiple closely-spaced upright leaders and (iii) narrow inter-rows, regardless of tree spacing within the row. In NOS, planting density can be reduced compared with super-high and ultra-high density planting systems on dwarfing rootstocks, utilising a wider range of rootstock vigours coupled to proportional increases in both within-row tree spacing and upright leader number per tree. This paper reviews the development of NOS and results of research carried out on apple, pear, sweet cherry, peach, nectarine, apricot and plum in production regions worldwide. The history of orchard …

Fruit Tree Responses To Water Stress: Automated Physiological Measurements And Rootstock Responses, William D. Wheeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

New orchard plantings utilize trees grafted to dwarfing rootstocks planted close together to facilitate larger harvests. These dwarfing rootstocks have not been comprehensively studied for their ability to withstand drought. This is of special importance in the Intermountain West which has limited rainfall. Additionally, orchard growers face competition for water from a growing population and increased uncertainty in rainfall from climate change. My research examined the use of dendrometers, which measure changes in trunk diameter, and sap flow sensors, which measure how quickly sap moves, as methods to inform growers about tree water status. I also used a weighing lysimeter …

A Field Study Of The Predatory Mite Metaseiulus Occidentalis Overwintering In Apple Orchards In The South West Of Western Australia, K. J. Lacey

Horticulture published reports

The twospotted mite (Tetranychus urticae) is one of the major pests of horticultural crops in Australia, and can cause severe damage in deciduous tree fruit crops such as apples, pears and peaches if left unchecked (Seymour 1982).

This study was conducted to determine whether the predatory mite Metaseiulus occidentalis, once introduced into orchards in the south west of Western Australia, could survive through the winter period and repopulate the orchard the following season. Two orchards in the Manjimup region where M. occidentalis had been released in the early summer of 1990/91, were selected for the study.

On-tree shelters were placed …

The University Fruit Farm At Union, Nebraska, C. C. Wiggans

Nebraska Agricultural Experiment Station: Historical Circulars

The University Fruit Farm may be considered as a substation or detached portion of the Nebraska Experiment Station. It was established to assist in answering questions pertaining to fruit production, and only experiments of this sort are carried on. Supervision of this property rests with the Department of Horticulture of the Nebraska College of Agriculture. This circular has been prepared with the view of furnishing visitors to the farm with a brief outline of the experimental projects. Further information is available from either the local foreman or from the Department. Visitors are always welcome and helpful suggestions are solicited.
