plants. In Virginia, Pattison and Wolf (2007) have evaluated protected culture for season extension and report that a 7.3 × 60.9 tobacco greenhouse or high tunnel planted a density of ≈10 plants/m 2 can yield 619 g/plant for an approximate 60-d period

results indicate that high tunnels can effectively and economically be used in the Intermountain West as an early-season extension technique for strawberries. Fall planting dates for the in-ground tunnel and the east–west-facing vertical systems were

Lettuce ( Lactuca sativa L.) is a cool-season crop; it achieves optimum growth and development at an average temperature of 18 °C. Production of lettuce at higher temperature ranges resulted in losses of yield and quality and led to some

Spunbonded polyester or polystyrene row covers were used as additional cold protection for spinach (Spinacia oleracea), kale (Brassica oleracea), pak choi (Brassica rapa) and P-types of lettuce (Lactuca savita) grown in ground beds under unheated polyethylene tunnels during the fall and winter of 1991 and 1992 in climatic zone 6. Temperatures inside poly tunnels averaged 2.4C warmer than outside. Average temperatures were 1.9C warmer than control under polystyrene and 1.5C warmer under spunbonded polyester. Average hourly temperatures showed both row covers offered significantly more cold protection than the greenhouse covering alone; but the two row covers offered similar protection from the cold. Row covers did not result in fresh weight differences in most of the species tested, except kale which had greater fresh weight in control. It may be concluded that during a similar mild winter, these cool season vegetables could be grown under unheated polyethylene tunnels with no additional protection necessary. When temperatures are lower, row covers could provide the protection required to produce these crops.

Numerous season extension techniques such as heated greenhouses, cold storage, root-cellars, cold-frames, variety selection, transplant production, and various means for food preservation have been used by farmers in temperate climates to ensure

’Rourke, 2015 ). Potential benefits of protected berry culture include season extension, increased yield, and decreased pest pressure. For example, using high tunnels can increase raspberry yield (including a greater percentage of marketable berries) per area
