In the years 1989-1993 greenhouse trials were carried out in order to determine the duration of chive dormancy and the yield in forcing starting at different times. The forcing of one- and two-year-old clumps began in autumn (with a variation form the middle of November to the beginning of December) and in winter (in the first or second ten days of January). Dormancy of plants usually started to disappear in November or December, and ended in December or January. Only in 1992/93 did the dormancy last longer. The two-year-old clumps usually produced earlier and gave a higher yield, which may indicate that their dormancy was not so deep as in the younger plants. In later forcing cycles the growth of leaves was faster than in the earlier ones. Forcing of the two-year-old clumps lasted a minimum of 3 weeks and of the one-year-old ones at least 4 weeks.
