Pruning has been used to reduce tree size, allow light penetration into trees, improve yield, improve fruit size and fruit quality, overcome alternate bearing, assist fruit harvest, and assist pest and disease control. The use of pruning has increased due to improving agricultural management techniques such as high planting densities, use of mechanical machinery in orchards and the need for effective pesticide and pathological chemical spray applications. The main objective of this study was to obtain a practical means of manipulating lemon trees at the right time. Pruning at the correct time to cultivate productive trees that produce quality fruit would have financial benefits. Lemon fruit quality is dependent on market demand and involves a number of features such as fruit shelf life, rind thickness, fruit size, rind colour, and juice content. The study was conducted on ’Eureka’ lemon trees budded on C. volkameriana rootstock, bearing the fifth and sixth commercial crops in 1999 and 2000 respectively. Twelve monthly pruning treatments per year were conducted on one row of trees starting in December 1997 (site 1) and repeated in the second year on the adjacent row of the same orchard starting in December 1998 (site 2). Selective pruning heading cuts were applied below the intercalation on the intercalary units. Potential branch bearing units were tagged and assessed during the harvest and flowering periods. Summer pruning between 16 to 19 months before the subsequent April/May harvest, resulted in the longest and most complex (intercalation sprouted per axil) vegetative response. The estimated crop value indicated that summer pruning treatments produced the highest income. This was ascribed not to differences in fruit size or quality, but to an increase in yield. The industry’s trend is to prune citrus from post-harvest to the pre-bloom stage. Results from this study have provided a beneficial cultural practice to prune during the summer months and provides a practice to optimise farm production and profit margins.

This study analyses the adoption of some innovations by Okanagan Valley orchardists. Comparisons were made with findings on the adoption of innovations by American farmers. Also included in the study is an evaluation of the 1964 televised chautauqua produced by the Horticultural Branch of the British Columbia Department of Agriculture. This style of chautauqua (which may be defined as an assembly for educational purposes, lectures, entertainment, etc.) replaced an earlier version held in district halls throughout the Okanagan Valley. The data were gathered by interviewing a sample of Okanagan Valley orchardists from the population of orchardists in the area served by the 1964 T.V. Chautauqua and who were also included in the 1960 Orchard Survey of the Okanagan Valley. Generally, adoption theory, as developed from studies in other countries, can be applied to a specific Canadian setting. Earlier adopters of innovations were more active educationally, had been in orcharding longer, had larger and more valuable orchards, and sold more orchard products than later adopters. These results coincide with past studies. However, the vast majority of the early adopters were full-time orchardists, while other studies have found part-time farmers to be the most innovative. Also, this study found complete ownership of the farm to be a characteristic of the later adopters while other studies have found this characteristic of early adopters. Two differences with previous studies were found in the use of sources of information. Agricultural agencies increased in importance between the awareness and interest stages in the adoption process. Also unique to this study was less use of mass media and agricultural agencies by the earlier adopters than the later ones. Evidence of a two-step concept of the diffusion of technological innovations was found with innovations flowing from their place of origin to the earlier adopters and from them to the later adopters. Innovativeness was found to be a general characteristic of certain respondents in that they adopted most innovations. The T.V. Chautauqua was more valuable than its predecessor in one respect; more of the laggards (who use fewer agricultural agencies than most orchardists) watched the televised program than attended the district hall chautauqua. This study is limited by the use of a sample to gather data, the use of an incomplete population list for sampling and inconsistencies in the interpretation of questions and answers by the interviewers. / Land and Food Systems, Faculty of / Graduate

Jackson County, Oregon is noted for the production of high quality pears. It is the fourth leading pear producing county in the United States and is the number one producer of winter pears. This thesis analyzes in detail the many aspects of the pear industry in the county. Climate, soils, topography, and progressive growers have been the main localizing factors. The study revealed that 200 growers produce the average annual total of three million boxes of pears on 9940 acres of bearing orchards. The pears are prepared for market in 12 packing houses and two canneries. The industry has a direct impact on the county of $15,000,000. The problems confronting the industry are caused by physical and biological factors. Spring frosts and hail damage are problems imposed by the climate. Pear Blight, Pear Decline, and Pear Scab are the main diseases. Insect pests such as the Pear Psylla and the Codling Moth must also be combatted. Urban encroachment has not yet been a serious problem in the county. The future for the industry appears to be stable, with little change in acreage. The fruit gift box industry will become of increasing importance, thus creating further emphasis on producing winter pears. / Graduation date: 1963
