EFFECT OF APPLICATION LIQUID ORGANIC FERTILIZER OF FRUIT WASTE ENRICHED BY ORGANIC SUBTANCES TO SHALLOT YIELDLena Walunguru, Marsema Kaka Mone and Yulian AbdullahAbstract Liquid organic fertilizer (LOF) made from fruit waste enriched by organic substances to increase macro nutrients, which are gamal leaves (for N source), banana stem (for P source) and coconut fiber (for K source) can be applied to organic farming systems. The purpose of this study was to determine the effect and to obtain the best concentration of LOF of fruit waste with and without N, P, K nutrient enhancing organic substances on the growth and yield of shallots. The research was carried out in May-November 2021 in Lasiana Village. The experiment used a Randomized Block Design, with 10 treatments which were LOF of fruit waste with and without N, P, K nutrient enhancing organic substances using a similar concentration (30, 35, 40, 45, and 50 ml/l water for these two types of LOF). Observation variables were: plant height, number of leaves, number and wet weight of tubers per clump. The results showed LOF of fruit waste with N, P, K nutrient enhancing organic substances had a better effect on all observed variables than LOF of fruit waste without N P, K nutrient enhancing organic substances. The best concentration was 45 ml/l of water from LOF of fruit waste that was with nutrients enhancing organic substances N, P, and K which resulted in a plant height of 31.43 cm (6 weeks after planting.); number of leaves 40.25 strands (6 weeks after planting); the number of tubers per clump (11.83 bulbs); and tuber wet weight per clump (28.80 g). |
