| Abstract:
Japanese cucumbers were grown in southwestern Canada (on southeastern Vancouver Island) by rock-wool culture in an OVALTECH greenhouse. Optimum cropping schedules were studied in 1992 and 1993. Cucumbers seeded in December had depressed vegetative growth during the early growing stage and because of the low light intensity fruit production and quality in the following harvest were below average. Those studies indicated that seeding should not be done prior to January. Advantages of a cropping system using large seedlings was examined in 1994. Two different cropping systems (A & B) with combinations of four cropping programs and three varieties were examined and com-pared to a one variety program of a single and long term culture system. System (A) consisted of a long harvest group (19 weeks) replaced with a short harvest group (13 weeks) while system (B) consisted of a short harvest group (13 weeks) replaced with a long harvest group (17 weeks). Seedlings with ten to twelve leaves were used as replacements to minimize the non-harvest period. The total yield of these systems surpassed the previous usual cropping system yield and with improved marketable fruit production, and without added cultural labor such as pruning of malformed fruits. | |
