Abstract


The objective of study is to determine effects of inorganic fertilizers and organic fish fertilizers on growth and yield of spinach in aeroponic system. The study was conducted in 2024 at Tien Giang Center of Applied Research and Science Technology Services. The experiment was arranged in a completely randomized design with seven treatments and three replications. The treatments were included components as NT1 (1400 ppm inorganic fertilizer – control); NT2 (1120 ppm inorganic fertilizer + 280 ppm organic fish fertilizer); NT3 (840 ppm inorganic fertilizer + 560 ppm organic fish fertilizer); NT4 (700 ppm inorganic fertilizer + 700 ppm organic fish fertilizer); NT5 (560 ppm inorganic fertilizer + 840 ppm organic fish fertilizer); NT6 (280 ppm inorganic fertilizer + 1120 ppm organic fish fertilizer); NT7 (1400 ppm organic fish fertilizer). The result showed that spinach grew well in the aeroponic systems when treated with NT1 (1400 ppm inorganic fertilizer) and NT4 (700 ppm inorganic fertilizer + 700 ppm organic fish fertilizer) with corresponding tree height results 38.90 cm; 38.97 cm; plant weight 87.07 g/plant; 87.03 g/plant and yield 4.04 kg/m2; 4.00 kg/m2 higher than other treatments.
