Abstract

The research was carried out at Can Tho to determine a suitable nutrient solution for the growth and yield of tatsoi and red pak choi grown hydroponically. The experiment was arranged in a completely randomized design with 3 treatments and 8 replications. The three treatments were three different types of nutrients: (1) DDTM – Commercially available nutrient solution on the market, (2) LV1 – Nutrient solution supplemented with iron based on the LV formulation, (3) LV – Nutrient solution for leafy vegetables. For tatsoi varieties, nutrient solution 1 and nutrient solution 2 resulted in growth indicators such as plant height, number of leaves per plant, leaf length, leaf width, and yieldhigher than that of nutrient solution 3. On thered pak choi, nutrient solution 1 resulted in the highest values in leaf width (13.3 cm), stem diameter (6.42 mm), plant weight, and commercial yield (3.43 kg/m²). The research results can be applied to the hydroponic production of tatsoiand red pak choi.
