Comparative study of einkorn, emmer, khorasan and modern wheat: agronomic performance

Output: Bijdrage voor congresCongres - Meeting abstract

Both farmers, bakers, millers and consumers are interested in diverse alternative crops that can give a higher economic and nutritional value. “ALTERGRAIN: More diversity in agriculture and food: opportunities for alternative and pseudo cereals in Flanders (2016 – 2018)” is a multidisciplinary research project at the University College of Ghent. The project studies a selection of alternative cereals through a whole chain approach which is deployed in de field and processing phase, the nutritional aspects before and after processing into derived foods and the economic potential of these crops for the Flanders’s region.
The project ALTERGRAIN has carried out a detailed study on the cultivation potential of the wheat species einkorn (Triticum monococcum), emmer (Triticum dicoccum) and khorasan (Triticum turgidum ssp. Turanicum) in comparison to modern wheat (Triticum aestivum). For this purpose, field trials were conducted at diverse Belgian locations with different soil types with conventional farming techniques (Experimental farm Bottelare (sandy loamy), PIBO Tongeren (loamy) , Inagro Koksijde (claysoil)) as well as one trial with organic cultivation in Everbeek (sandy loamy soil). In several randomised field trials four einkorn wheats, nine emmer wheats, one khorasan wheat and two modern wheats were grown in 2016 and 2017 (summer and winter varieties). Plots of 15 m² were sown with four replications. Several factors were included in the field trials: sowing density, nitrogen fertilization and application of a growth regulator. The obtained data demonstrate substantial differences in plant development, lodging, disease sensitivity, yield potential and quality of the local grown crops in 2016 and 2017 in comparison to modern wheat.
Mean grain yield of einkorn, emmer and khorasan were 40, 35 and 65% lower than that of modern bread wheat. Furthermore the hulled wheat crops einkorn and emmer require a dehulling treatment with 30 to 40% weight loss. Also the ancient wheat species were taller than bread wheat. Consequently, to avoid lodging, farmers should aim at reducing the plant height by taking into account sowing density, low amount of nitrogen in comparison to modern wheat and application of a growth regulator. With the current farming techniques in Flanders, einkorn as well as emmer wheats were cultivated with comparable results as mentioned in literature for other regions. During two years of cultivation, the tested khorasan variety showed a high disease sensitivity in the Flanders’s climate in comparison to einkorn, emmer and modern wheat. Currently the seed cost of ancient wheat species is substantial higher in comparison to modern wheat due to a decreased availability on the seed market. Consequently all further agents in the food chain will have to take into account a higher cost.
