| Abstract | Four blackberry (Rubus L. subgenus Rubus Watson) cultivars (‘Obsidian’, ‘Black Diamond’, ‘Metolius’, ‘Onyx’) and two advanced selections (ORUS 1939-4 and ORUS 2635-1) were evaluated during the establishment years of an organic production system for fresh market. The planting was established in Spring 2010 using approved practices for organic production and was certified organic in 2012, the first fruiting year. Plants were irrigated using a dripline under a woven polyethylene groundcover (weed mat) installed for weed management. Liquid fertilizers injected through the drip system were used at rates of 56 kg·ha⁻¹ total nitrogen (N) in 2011–12 and 90 kg·ha⁻¹ total N in 2013. Genotypes differed in the level of nutrients measured in primocane leaves. Tissue phosphorus (P), potassium (K), sulfur (S), iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) concentrations were within the recommended standards, but tissue calcium (Ca), magnesium (Mg), and boron (B) were deficient in some or all genotypes. Although two cultivars and both advanced selections responded well in terms of plant growth and yield to the organic production system used, yields in ‘Onyx’ and ‘Metolius’ were considered low for commercial production. In contrast, the higher yielding ‘Obsidian’ and ORUS-2635-1 appeared to be the best suited for organic fresh market production as a result of larger fruit size, greater fruit firmness, higher sugar-to-acid ratios, lower postharvest percentmoisture loss in ORUS-2635-1, and the longest number of marketable storage days at 5°C in ‘Obsidian’. |
