Abstract

The objectives of this research were to study the effect of bio-extract and chemical fertilizer on the growth and yield of spinach (Spinacia oleracea L.) growing in a hydroponic system. The experiment was set as completely randomized design. The applications of fertilizer were using six treatments; A + B standard solutions (control), 15-15-15, bio-extract from vermiculture, 15-15-15 + bio-extract from vermiculture (1:1),15-15-15 + bio-extract from vermiculture (1:3) and 15-15-15 + bio-extract from vermiculture (1:5), EC = 1.4  mS/cm and pH = 5.8-6.0. The result of experiment were found that the using of A + B standard solution was the highest survival, height, fresh weight and nutrient content of 70%, 8.9 cm, 4.84 mg / g (K), 0.59 mg / g (Mg), 0.88 mg / g (Ca), 0.01 mg / g (Fe), 0.03 mg / (Beta-carotene) and 0.01 mg / g (Chlorophyll), respectively.
