Autumn field experiments were carried out from 1996 to 1998 with 7 hybrid cultivars of Chinese cabbage (‘Asten F1’, ‘Morillo F1’, ‘Nemesis F1’, ‘Parkin F1’, ‘Sapporo F1’, ‘Spectrum F1’, and ‘Taranko F1’), grown from potted transplants (peat pots 4󫶘 cm) and non-potted ones (seed-bed). The best productive effect was achieved with the use of potted transplants. The total yield amounted to, on average, from 63.34 t ha-1 (1996) to 89.23 t ha-1 (1997) and the marketable yield ranged from 44.25 t ha-1 (1996) to 82.69 t ha-1 (1997). Great productive potential was characteristic of ‘Sapporo F1’ and ‘Taranko F1’ cultivars, whose marketable yield was very high, especially in 1997 (106.26 and 101.90 t ha-1 respectively). The use of non-potted transplants had an unfavourable effect on both total (from 20.70 t ha-1 in 1998 to 47.83 t ha-1 in 1996) and marketable yield (from 11.29 t ha-1 in 1997 to 30.70 t ha-1 in 1996). Mean head weight amounted to from 0.60 kg to 1.63 kg. A decrease in the mean weight of heads of non-potted plants in two research years was observed. The heads of potted plants contained, on average, from 4.05% (1998) to 5.74% (1996) of dry matter and from 20.02 mg% (1998) to 25.11 mg% (1997) of L-ascorbic acid. The heads of Chinese cabbage grown from non-potted transplants contained from 4.94% (1998) to 6.09% (1997) of dry matter and from 20.53 mg% (1998) to 32.71 mg% (1996) of L-ascorbic acid respectively.
