Özet
A two-year study was performed on red cabbage (Brassica oleracea L.var.Rubra) to assess theeffect of different irrigation levels on yield, sugar and organic acid contents. The study wasconducted using drip irrigation system on a clay loam soil. The volume of irrigation waterapplied with 4-day intervals to each treatment was based on Class-A pan evaporation (Ep). Inthe full irrigation treatment (I1.0), a pan evaporation using screen covered Class-A pan wasmeasured with 4-day intervals and all amount of evaporation was applied in the normal(1.00xEp) treatment, and deficit amounts were imposed on three irrigation treatments as I0.7(0.7xEp), I0.3 (0.3xEp), and I0.0 (0.0xEp). The plant-available soil water at maturity and yield ofred cabbage was significantly related to irrigation amounts. Imposition of deficit irrigationresulted in yield reduction, especially in the severe stress treatments I0.3 and I0.0. Therefore,yields were related linearly to irrigation. That’s why, if there is no water scarcity full waterdemand of red cabbage need to be compensated for the whole growing season. However, inthe deficit treatment, total sugar and especially ascorbic, oxalic, tartaric and malic acidcontents increased, and only lactic acid decreased, on the other hand there was no significanteffect of different water levels on the content of citric acid.
