CollectionA collection of Bernadine Strik's works relating to berry crop production systems and breeding. Includes documents on blackberries, blueberries, raspberries, caneberries, table-grapes, and kiwifruit cultivars.
Berries and Grapes
Evaluation of Advanced Selections for Commercial Potential in the Pacific Northwest
Oregon has a diverse, economically important berry crop industry with about 23,000 acres harvested for a farm gate...
ArticleEvaluate the effect of weed management, irrigation, and training time on machine-harvested yield and quality, plant growth, nutrient allocation, and food safety in 'Marion' and 'Black Diamond' blackberries.
PresentationThis is the research poster for the article on "seasonal changes in leaf nutrient concentration of male and female hardy kiwifruit grown in Oregon". It includes condensed information about the research and results.
The Impact of Severity and Time of Tipping and Hedging on Performance of Primocane-fruiting Blackberry in a Tunnel
Online ResourceOn average, canes that were hard-tipped produced more branches and had more fruit/cane than soft-tipped canes. Canes that were tipped early (22–27 June) produced more fruit/cane than those tipped later (7–24 July). When canes were hard-tipped early in the season, the number of fruit/cane was increased threefold compared with soft-tipping canes early.
Foliar Calcium Applications Do Not Improve Quality or Shelf Life of Strawberry, Raspberry, Blackberry, or Blueberry Fruit
Online ResourceFoliar calcium (Ca) products are applied by many berry growers to enhance fruit quality and shelf life without evidence that these applications increase fruit Ca or impact fruit characteristics when applied at rates recommended on the product label. The objectives of this study were to determine if fruit or leaf Ca increases when several formulations of liquid Ca products are applied to developing fruit, and to assess any resulting changes in fresh market quality of berries.
Leaf nutrient concentration in blackberry - recommended standards and sampling time should differ among blackberry types
Online ResourceLeaf tissue sampling is a critical aspect of a nutrient management program in commercial blackberry production. Tissue nutrient levels and sampling requirements may differ among these blackberry types. Two studies were conducted to assess the impact of blackberry type and cultivar on tissue nutrient concentration of leaves sampled every 2 weeks over two growing seasons. Fertilizer recommendations based on leaf nutrient sufficiency levels specific to the diverse types of blackberry grown will aid growers, potentially reducing over application of fertilizer nutrients.
