In spring of 1993 and 1994, mature 'Marion' (Rubus sp.) plants were pruned to 0, 4, 8, and 12 floricanes. An additional treatment of 0 floricanes with early (30 cm) primocane pruning was included. Primocane growth was measured from emergence in April until growth cessation at the end of October....
The effect of primocane management on flowering and fruiting patterns was studied in primocane-fruiting blackberry (Rubus subgenus Rubus, Watson) cultivars 'Prime-Jan'® and 'Prime-Jim'® over two years. Primocanes that were "soft-tipped" (upper 2-5 cm removed) at 1.0 m were compared to un-tipped canes. In both years, soft-tipped primocanes developed 2-3 fold...
The effect of primocane removal and training time on yield components and cold hardiness of 'Marion' trailing blackberry was studied. In 1991, primocanes were either not cut, or cut at ground level from plants on a single occasion at one month intervals from late April to late July. Four canes...

Oregon is known around the world for its blackberries. We have an ideal climate, with warm, clear, summer days and cool nights, so our berries reach peak flavor and quality. We also grow excellent black and red raspberries. Blackberries are distinguished from raspberries by whether the fruit retains its receptacle...
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...
This publication describes blackberry cultivars, including trailing, erect, semierect, primocane-fruiting erect, and blackberry/red raspberry hybrids. It includes information on commercial value and identifies which cultivars work well for home gardens.

There is renewed interest in agroforestry as a management strategy for marginal agricultural lands in western Oregon. Silvopastoral systems combine tree and
forage production, which involve crops and practices familiar to the area. The objective of this study was to determine how
management influences the physiology and ecological interactions of...
