Two studies were initiated in June of 1981 in order to gain greater understanding of the growth and fruiting habits of field grown strawberries in Oregon's Willamette Valley.
Yield component analysis of 'Benton', Oregon's leading cultivar and an advanced breeding selection, 'OR-US 4356' was conducted during the first (1981) and...
Winter squash is an important late winter vegetable crop for local and regional markets; however, farmers in western Oregon report that this crop is marginally profitable due to losses in storage and relatively low yields for the high culinary value kabocha and buttercup types. In order to increase the sales...
Cover crop establishment in late-season crops, like sweet corn, may be difficult due to the relatively short operational window following crop harvest. In regions like western Oregon, where fall-precipitation can occur when the crop is still in the field, cover crops may not be able to be planted, due to...
The study was conducted in an organic trailing blackberry (Rubus L. subgenus Rubus, Watson) planting established at the North Willamette Research and Extension Center in Aurora, OR on 26 May 2010. Three weed management systems were compared for 'Marion' and 'Black Diamond': 1) non-weeded; 2) hand-hoed two to three times...
Relatively little is known about aboveground nutrient content of organic blackberry, and there is no published work on total carbon (C) content. Treatment effects on biomass, C, and nutrient content, accumulation, and removal were assessed over 2 years in a mature organic trailing blackberry (Rubus L. subgenus Rubus, Watson) production...
Organic production of blackberries is increasing, but there is relatively little known about how production practices affect plant and soil nutrient status. The impact of cultivar (Black Diamond and Marion), weed management (nonweeded, hand-weeded, and weed mat), primocane training time (August and February), and irrigation (throughout the summer and none...
Weed management, training time, and irrigation practices were evaluated from 2013 to 2014 in a mature field of trailing blackberry (Rubus L. subgenus Rubus Watson) established in western Oregon. The field was planted in 2010 and certified organic in 2012, before the first harvest season. Treatments included two cultivars (Marion...
There is limited information available on production of trailing blackberry, particularly certified organic plantings, which are of interest to growers as there is increased consumer demand and a price premium over conventionally-produced fruit. Various production strategies were evaluated for their effect on yield, biomass production, carbon (C), and nutrient concentrations...
Weed management practices were evaluated in a new field of trailing blackberry (Rubus L. subgenus Rubus Watson) established in western Oregon. The field was planted in May 2010 and certified organic in May 2012. Treatments included two cultivars, Marion and Black Diamond, grown in 1) non-weeded plots, where weeds were...
A study was conducted in western Oregon to assess the impact of cultivar and weed management strategy on accumulation and loss of plant biomass and nutrients during the first 3 years of establishment when using organic fertilizer. The study was conducted in trailing blackberry (Rubus L. subgenus Rubus Watson) planted...
