During a three-year field experiment, the possibilities of cultivating the ‘Performer’ cultivar of Japanese bunching onion for early harvest bunching were assessed through the use of autumn and spring planting terms. The seedlings, produced in multi-pots, were planted in the open field on 8-10 September, 9-10 October and 6-12 April, and covered with a perforated foil and agrotextile in mid-November or directly following the spring planting. The covers were removed at the end of April, and the harvest of Japanese bunching onion was conducted at the end of May. The percentage of plants that survived the winter, how many produced flowering stems and the height of the total and marketable yield of plants with a pseudostem diameter >10 mm were determined. We evaluated the content of selected components with a nutritional value in samples of edible plant parts.
