Fifteen years of research and development aimed at the production of high-quality earlywinter strawberries in the Negev desert, are concluded. This goal required synchronization of seasonal yields with the peaks of the markets' demand, November− February. For this purpose, selected infra short-day (ISD) cultivars were used. Rooted plug plants with enhanced capacity of simultaneous fast vegetative growth and fruiting were produced. Production was carried out in greenhouses and various protocols aimed at yield enhancement were tested. Currently, drip-fertigated, eye-level hanging soilless system, with plant density at about 200,000 plants ha−1, combined with biological pest management program, are employed. This system brought about a two-fold increase in yield compared to soil culture (80–100 t ha−1), significantly reduced risks of soil- and air-borne diseases, reduced the use of fungicides, and eased extensive labor demands. However, beyond substantial refinements of practices, a significant proportion, 15–25% of the seasonal high-quality yield, was harvested during the earlier two months with no reduction in the total yield or fruit quality. In this chapter, the state of art in early-winter strawberry production is portrayed, including principles, approaches, and methods that have been used and improved during the project. Additionally, ideas for further possible enhancement are discussed.
