Three sowing densities did not affect the growth and yield (commercial yield of 0.78 kg/m2) and the quality of watercress. The experiment 2 was designed in split-plots with three replications. Two main plots were two varieties of watercress: (1) The introduced variety and (2) Local variety as control. Four sub-plots were foliar fertilizer: (1) without foliar fertilizer as control, (2) Balado Complete fertilizer, (3) Spirulina fertilizer and (4) Balado Complete fertilizer + Spirulina fertilizer. The results showed that introduced varieties had a commercial yield of 3.20 kg/m2, the main stem length, number of leaves and shoots were lower than local varieties (commercial yield of 4.80 kg/m2), but the introduced variety had an average weight of plants, stem diameter and anthracnose rate higher than that of local varieties. The quality of introduced and local watercress varieties was similar. About 4 types of foliar fertilizers: The commercial yield (4.57 kg/m2) of watercress when using Balado Complete fertilizer+Spirulina fertilizer was higher than that of watercress without separate Balado Complete fertilizer or Spirulina fertilizer.
