Comparison of yield and nutritive value of einkorn, emmer and spelt produced by prehistoric technology
Habětínková, Kateřina ; Hejcman, Michal (advisor) ; Pavlů, Vilém (referee)
Triticum monococcum (einkorn wheat), Triticum dicoccum (emmer wheat) are the main cereals planted by the first European farmers since 5600 B.C. Triticum spelta (spelt wheat) is planted since Roman period. The aim of the thesis is comparison of yield and nutritive value of einkorn, emmer and spelt produced by prehistoric technology. There is almost nothing known about planting wheat under prehistoric conditions. To fill this gap, an experiment on experimental field in Praha Suchdol were performed. There was used technology of broadcast seeding, with no weeding. The obtained data were used to define yield parameters (HTS, Hulled index, yield [t/ha]) and concentrations of monitored elements (N, P, K, Ca, Mg, Cu, Fe, Mn, Zn, Cd a Pb), which affect nutritional value of wheat. Yields were 1.01, 1.38 and 0.99 t/ha, HTS was 27, 28.7 and 39.3 g and Hulled index was 0.71, 0.72 a 0.70 for einkorn, emmer and spelt. Results were compared between species and with other authors. The grain yields do not correspond with other authors, they are lower. Low yield and dilution effect absence caused, that concentration of minerals (especially nitrogen) were higher (30.5, 31.3 and 30.3 g/kg) than common values of mineral concentration. Surprising values were observed for Zn (39.7, 43.9 and 36.9 mg/kg). Concentrations of Zn were very low, which may be caused by poor mobility of Zn in soil, due to high pH. We observed statistically significant differences between einkorn, emmer and spelt.
