The Stiles bent fence (SBF) and single-sided shift trellis (SSST) are differently designed structures that function to isolate fruiting zones of summer-fruiting brambles on one side of the plant or row. The SBF and SSST are suited for use with cultivars that produce long, flexible, nonbranched canes. Summer pruning of stiff-caned, semi-erect types may encourage development of long, flexible lateral branches that are adaptable for training on these trellises; alternate-year cropping may be helpful where such pruning is necessary. The SSST operates on the same principles as our original single-sided trellis (SST), but the newer design is compatible with a broader range of commonly available construction materials. Construction plans will be published in a Virginia Agricultural Experiment Station Bulletin as soon as funds are made available. The SSST should allow greater manual harvest efficiency, more effective IPM, fewer yield losses to sunscald, compatibility with cultural management practices, lower costs of postharvest precooling, better condition of harvested fruit for maximum shelf life, and stronger prospects for machine harvesting of fresh-market brambles.

Trellising was evaluated for its effects on yields of cucumber (Cucumis sativus L.) cultivars Dasher II, Marketmore 76, and PetoTripleMech at Lane and Wilbutton, Okla. Trellising improved total and marketable yield at both locations compared with ground culture. `PetoTripleMech', evaluated as a fresh-market cultivar, produced yields equal to, or higher than, the other cultivars. Average marketable fruit weight was not affected by trellising but was affected by cultivar at Lane, with `PetoTripleMech' having the heaviest fruit. Economic analysis indicated that trellising is a viable management system for small-scale cucumber production.

Recently, an approach was described for continuous monitoring of growth and estimating yield in grapevines or other trellised crops [Trellis Tension Monitor (TTM); Tarara et al., 2004 , 2005 ]. Briefly, the technique involves continuous

Trellising was investigated for intensive, small-scale, fresh market cucumber (Cucumis sativus L.) production. Economic feasibility of trellising was examined. The cultivars Dasher II, Marketmore 76, and PetoTripleMech were evaluated using trellising and ground culture at two locations in Oklahoma. The cultivar PetoTripleMech is normally grown as a processing cucumber. Here it was evaluated as a fresh market entry. Trellising significantly improved marketable yield of the three cultivars at both locations in comparison to ground culture. PetoTripleMech yields were equal to, or better than, the fresh market standards Dasher II and Marketmore 76. Average marketable fruit weight was not affected by trellising. Economic analysis indicated that trellising is a viable management system for small-scale cucumber production because the gross and net returns to the producer were increased by 20% and 10% respectively.

severance, the grapes are left on the trellises to dry, so DOV vineyards do not require sunlit drying areas between the rows, as tray-dry systems do. Therefore, DOV vineyards may use larger, more expansive trellises that greatly increase yield potential

. This system can augment yield per surface area unit to a certain point after which, as a result of competition among plants, it declines ( Duthie et al., 1999 ). The use of “trellises” as a management system offers a series of agricultural advantages
