Abstract:
The study aimed to determine the effect of the use of organic liquid fertilizer trash fish waste to the development of spinach plants (Amaranthus sp) and kale land (Ipomoea reptans). The characteristics of the resulting liquid fertilizer has a pH 6.88, N 2:27%, P 19.61%, C 13.75%; K 7.92%; Cd 0.0013 mg/kg; and 0.0275 mg Pb/kg. The results of the study test application of liquid fertilizer trash fish waste to plant development spinach and kale showed accretion effect on plant height, length/leaf area, leaf amount and weight of the plant/stem of the plant during the growing season for 5 weeks. The development of spinach plants for 5 weeks with liquid fertilizer and control treatments to increase plant height, length/leaf area, leaf amount, and weight of spinach plants in sequence are: height 24.1+0.31 and 17.3+0.29 cm; length/leaf area 6.7+0.23 cm and 5.3+0.17 cm; quantity of leaves 12.7+0.72 and 9.8+0.67 strands, and heavy plant and 12.3+0.51 g and 9.1+0.65 g/plant stems. For the development of spinach plants for 5 weeks with liquid fertilizer and control treatments to increase plant height, length/leaf area, leaf amount, and weight of kale plants are: height 23.9+0.43 cm and 18.9+0.47 cm; length/leaf area 7.7+0.37 cm and 6.8+0.4 cm; quantity of leaves 16.3+0.63 and 14.5+0.55 strands; and heavy plant and 17.3+0.59 g and 14.6+0.63 g/plant stems
