Creator:: Fernandez-Salvador, Javier A.
Abstract:: The impact of fertilizer source and cultivar on growth, fruit quality, and yield was evaluated in organic blackberry (Rubus L. subgenus Rubus Watson) from 2011-2013 in three studies. In all studies, plants were drip irrigated, and weeds were managed using a woven polypropylene, permeable landscape fabric (weed mat). At a...

Creator:: Garrett, Amy
Abstract:: Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

Creator:: Sullivan, Dan M., Peachey, Ed, and Donaldson, Andrew
Abstract:: Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...

Creator:: Harkins, Renee H.
Abstract:: 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...

Creator:: Larco, Handell O.
Abstract:: A 0.4 ha planting of blueberry (Vaccinium corymbosum L.) was established in Oct. 2006 to evaluate the effects of cultivar (Duke and Liberty), planting method (flat versus raised beds), weed management (sawdust mulch and hand-weed control; compost plus sawdust mulch with acetic acid, flaming, and hand-weeding used as needed; and...
