Planting density is an important factor to determine crop productivity and spacing efficiency in vegetable production systems. In this study, the growth and yield of hydroponically-grown pak-choi (Brassica campestris ssp. chinensis) were investigated under five different planting densities (27, 33, 44, 67, and 133 plants/㎡). Number of leaves and top fresh weight per plant were decreased with increasing the planting density, while yields per area were increased reaching the maximum value at 133 plants/㎡. Maximum crop growth rate, light use efficiency yield, and yield index, which are closely related with planting density, were the highest at 67 plants/㎡. Especially the yield index was 23-31% higher at 67 plants/㎡ than that at 33 plants/㎡, The marketable rate, which was 100% between 27 and 44 plants/in", was sharply decreased with increasing the planting density and then became the lowest at 133 plants/㎡ due to the poor light environment, while the marketable yields per area were the highest at 67 plants/㎡. From a practical point of view, the marketable yield per area was an appropriate factor to evaluate the planting density in hydroponics, a 67 plants/㎡ (15 × 10 ㎝) was considered as an optimum planting density for hydroponically-grown pak-choi.
