WEED, WATER, AND NUTRIENT MANAGEMENT PRACTICES FOR ORGANIC BLACKBERRY PRODUCTION
Project Number: 5358-21000-042-06
Start Date: Sep 17, 2009
End Date: Sep 30, 2013
The objectives of this study are to develop best irrigation and fertigation practices and weed management systems in organic ‘Marion’ and ‘Black Diamond’ machine-harvested for processing. In addition to developing a feasibility study and cost analysis for organic trailing blackberry production, we will evaluate the impact of post-harvest irrigation on plant growth, yield, and quality, ascertain the incidence of cane disease, and determine the impact of weed presence on productivity.
A new planting will be established at the North Willamette Research and Extension Center on land in “transition”. Planting will be in spring 2010 such that the first fruit harvest in 2011 will be organic (certified by Oregon Tilth). Treatments include: cultivar (‘Marion’ and ‘Black Diamond’); irrigation (post-harvest and no post-harvest irrigation); weed management (weed mat, hand-hoed, and non-weeded); and primocane training date (August and February). Documents Grant with Oregon State University. Formerly 5358-21000-037-17G (8/2011).
