Effects of Biochar and Nitrogen-Enriched Soil Amendments on Plant Growth, Mineral Nutrition, and Early Fruit Production in Highbush Blueberry (Vaccinium sp.)

Creator:: Sales, Bryan K.
Abstract:: The goal of the work in this dissertation was to identify alternative soil amendments to improve plant growth and yield during establishment of highbush blueberry (Vaccinium hybrid). Woody materials, such as sawdust and wood chips, have a high carbon to nitrogen (C:N) ratio and low water holding capacity, which can...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...

Predictions and Practices for Reducing Heat Damage in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Yang, Fan-Hsuan
Abstract:: Heat-related fruit damage is a common problem in the northern highbush blueberry (Vaccinium corymbosum L). This is particularly true in regions such as the northwestern United States, where summers are warm and dry, and daytime temperature regularly exceeds 32 oC. Millions of dollars of fruit damage are reported in blueberries...

Nitrogen fertigation practices to optimize growth and yield of northern highbush blueberry (Vaccinium corymbosum L.)

Creator:: Vargas, Oscar L.
Abstract:: Northern highbush blueberry is a long-lived perennial crop that is well adapted to low soil pH conditions. The plants are often shallow rooted and absorb primarily the ammonium (NH₄) form of nitrogen (N) rather than nitrate-N (NO₃-N). Traditionally, commercial blueberry fields have been irrigated with overhead sprinklers and fertilized using...

Effect of organic production system and harvest date on the quality of blackberry fruit for fresh and processed markets

Creator:: Liu, Mingyang
Abstract:: Blackberry (Rubus sp.) fruit are a good source of phenolic compounds and anthocyanins, and are consumed in fresh and processed forms. Though organic products become more popular, limited information is available about how different organic production methods affect the post-harvest quality of blackberry fruit. The objective of this project was...

Improving in vitro mineral nutrition for diverse red raspberry and Rubus germplasm

Creator:: Poothong, Sukalya
Abstract:: Red raspberry, Rubus idaeus L., is a valuable crop for the U.S. Pacific Northwest and clonal propagation is required to produce disease-free plants and for germplasm preservation. One challenge of red raspberry micropropagation is the wide variation in growth response among the cultivars. The studies described in this dissertation were...

Variation and heritability of vegetative, reproductive and fruit chemistrytraits in black raspberry (Rubus occidentalis L.)

Creator:: Dossett, Michael
Abstract:: In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are ill adapted...

Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

Evaluation of evapotranspiration and irrigation performance in Oregon south coast

Creator:: Sriprisan, Sirikul (Indi)
Abstract:: This study was prompted by the need for improving the efficiency of irrigation systems at the Oregon South coastal areas. Accurate information about evapotranspiration (ET) rates is essential for maximizing the efficiency of irrigation systems. Currently, ET estimates provided by Bureau of Reclamation AgriMet Program are derived from the Kimberly...

An evaluation of blackberry harvest sanitation and the ability of foodborne pathogens to survive in blackberry products

Creator:: Sales, Melissa M.
Abstract:: Blackberries, genus Rubus, are an important Oregon agricultural commodity. In their fresh and processed forms, they offer many health benefits and may be able to help Americans better achieve fruit consumption recommendations because of convenience and pleasant sensory qualities. However, the susceptibility of blackberry products to contamination with bacterial pathogens...
