Two field experiments were conducted in order to optimize production
factors in early leeks, grown for harvest in July. The best quality
transplants and maximum marketable yield were obtained by sowings at the
beginning of January. Similar effects were noted from sowing carried out
two weeks later, while its further delay to February caused a significant
reduction in yield. Early leeks planted in mid-April responded well for
all types of covering used for 5 weeks from transplanting into the open
field. Among the tested covers flat perforated plastic with 50 holes per 1
m2 appeared to be slightly more efficient,
followed by a low plastic tunnel and Agryl P-17.
The method of planting did not affect the yield of leeks harvested early, until mid-July. For harvesting
at the end of that month the method most preffered was individual planting
of leeks with 25×8 cm spacing.
