Changes of Elements Concentration in Onion Set Plants (Allium cepa L.) Traditionally Cultivated Under Different Soil Types in Greece

A. Liopa-Tsakalidi, P.E. Barouchas and I.N. Xynias
The objective of this study was to record the traditional knowledge of the native variety, Chalcidos of onion set (Allium cepa L.) in Achaia Prefecture, Greece. The plants were grown in soil types [Sandy Clay Loam (SCL), Silty Loam (SL) and Clay Loam (CL)] in two cropping seasons. Field preparation and sowing was performed according to the traditional in the region farming practices. The seeds were produced by farmers in region during the former cropping season. Seeds of onion set were used at a density of 12 kg ha-1. The N, P, K, Ca, Mg and B content in onion set plants was lower when the plants were grown in CL field, compared to the respective values in SCL and SL, in either cropping seasons. No differences were recorded in Ca, Zn and Fe content in plants. Differences in Mn content were observed in the plants and the best value was noticed when the plants were grown in the CL field. The Cu content in plants was higher in CL field compared to the respective values in SCL and SL. Content variation of plants in P, K, Ca and Na and in Mn, Cu and Fe micro-elements exhibits a diminishable trend in either cropping seasons. The macroelements concentrations in onion set for all soil types and cropping seasons were lower (N:1,62%, K:2,09%, P:0,20%, Mg:0,19%) than those referred in literature and this record of the documentation of traditional practices in this study can be used for verification of traditional culture authenticity.
