The results of the first Polish trials on multi-seeded onions are
reported. Seedlings were raised in peat blocks with a target population of
5 plants/block. In a two-year experiment there was for transplants an
increase in marketable yield of 17.6 and 20.9 t/ha when planted at 50 and
66.6 plants per m2 respectively, as compared with direct drilling at a target density of 80-85 plants/m2.
At a target density of 83.3 plants/m2 and
with a 10-day interval in sowing and transplanting dates, no significant
differences in yield were found between the crops transplanted on 19 and
29 April, but the crop direct drilled on 6 April gave a significantly
higher yield than that drilled on 16 April. Early planting of transplants
(26 April) and large block size (120 ccs) increased the marketable yield
of multi-seeded onions by 6% and 8% respectively in comparison with late
planting (6 May) and small block size (60 ccs).
