Effects of container size, transplant age and spacing on yield of Chinese cabbage. [Abst.]

A:PS

Head weights of `Nagaoka 55` Chinese cabbage (Brassica campestris L. spp. pekinensis (Rupr.) were 76-79% greater at a plant spacing of 43 cm than at 28 cm. Percentage of both salable and grade 1 heads increased with increasing plant spacing. Seedlings were raised in cylindrical containers 2.5, 3.75, 5 and 7.5 cm diameter x 6.4 cm high for 3, 4, 5 and 6 weeks in a seeedling house. Transplant age affected days to maturity only minimally and did not affect yield. Seedling fresh weight was greater with seedlings in 7.5 cm containers than in the smaller containers at all transplant ages. Chinese cabbage transplanted from 7.5 cm containers matured 7.5 days earlier, produced 10% heavier heads and yielded 25-31% more than seedlings from 2.5 cm containers when data were averaged over all transplant ages. It is possible that plants from the larger containers performed better as a result of more favorable physical properties or fertilization regime of the container media. The highest yields in these trials exceeded 3000 kg/ha/day. [AS]
