In a field study conducted in 1991-1993 transplants of Kilima cv leeks
were produced from seed sown into pressed soil blocks, plastic rings, and
boxes or by pricking out the seedlings into soil blocks and plastic boxes.
Multi-seeded transplants comprising 2 or 3 seedlings were planted out in
the middle of April spaced at 25×16 cm and 25×24 cm, respectively, in
order to obtain a population amounting to 50 plants per 1 m2.
The results of the study showed that the most efficient way of transplant production,
providing the highest marketable yield of early leeks, appeared to be
direct drilling into pressed soil blocks and plastic rings. The
favourable effect of the pricked out seedling planting can only be
considered because of the smaller demand for a heating area in the
greenhouse for at least 6 weeks from the sowing date. With the same plant
population, multi-seeded transplants comprising 2 and 3 seedlings did not
affect the yield of leeks or crop quality.
