The Impact of Severity and Time of Tipping and Hedging on Performance of Primocane-fruiting Blackberry in a Tunnel

Online Resource

On average, canes that were hard-tipped produced more branches and had more fruit/cane than soft-tipped canes. Canes that were tipped early (22–27 June) produced more fruit/cane than those tipped later (7–24 July). When canes were hard-tipped early in the season, the number of fruit/cane was increased threefold compared with soft-tipping canes early.

Foliar Calcium Applications Do Not Improve Quality or Shelf Life of Strawberry, Raspberry, Blackberry, or Blueberry Fruit

Online Resource

Foliar calcium (Ca) products are applied by many berry growers to enhance fruit quality and shelf life without evidence that these applications increase fruit Ca or impact fruit characteristics when applied at rates recommended on the product label. The objectives of this study were to determine if fruit or leaf Ca increases when several formulations of liquid Ca products are applied to developing fruit, and to assess any resulting changes in fresh market quality of berries.

Leaf nutrient concentration in blackberry - recommended standards and sampling time should differ among blackberry types

Online Resource

Leaf tissue sampling is a critical aspect of a nutrient management program in commercial blackberry production. Tissue nutrient levels and sampling requirements may differ among these blackberry types. Two studies were conducted to assess the impact of blackberry type and cultivar on tissue nutrient concentration of leaves sampled every 2 weeks over two growing seasons. Fertilizer recommendations based on leaf nutrient sufficiency levels specific to the diverse types of blackberry grown will aid growers, potentially reducing over application of fertilizer nutrients.
