Uzgoj rukole (Eruca sativa L.) u semihidroponskom sustavu

For intensive vegetable production also on less suitable conditions and low quality lands, semihydroponic (thin layer) is a good alternative. At thin layer system, plants are cultivated on a thin media or substrate (2 to 10 cm). Substrate is laid on a PE-film, nutrient solution is delivered at the top level of the cultivation area. Nutrient solution flow moisturise the whole substrate. Although rucola is a very minor crop in Slovenia, it is increasingly popular vegetable in Central Europe and is spreading to other areas. Because of its high content of glucosinolate, this leafy vegetable is an effective antioxidant. In greenhouse experiment, which took place on the experimental field of the Biotechnical Faculty in Ljubljana from the end of September 1992 until February 1993, we have compared thin layer growing of rucola on four growing media (expanded perlite ; vermiculite, Glinopor (clay aggregate) and peat) with classic growing in soil. All plants were fertigated with the same system and same rates of nutrients. The results showed that leaf production was significantly influenced by the growing media. The best production of fresh mass was obtained using peat. However, the type of media had no distinct effect on the content of dry matter. An additional advantage of thin layer system was increasing the earliness of harvest. All types of media produced marketable yield of rucola in 60 days, while classic growing rucola would require a longer period to reach marketable.
