PENGARUH PEMBERIAN PUPUK ORGANIK CAIR LIMBAH KULIT PISANG RAJA TERHADAP PERTUMBUHAN DAN HASIL TANAMAN CABAI MERAH KERITING (Capsicum annuum L.)

Banana Var.Raja skin waste has nutrients that are useful for plants so that it can be used as a base for liquid organic fertilizer. This research aims to determine the levels of Nitrogen, P2O5, COrganic and Ratio C / N on organic fertilizer liquid Banana Var.Raja skin waste, found out the effect and the optimal dose of liquid organic fertilizer on Banana Var.Raja skin waste on growth
and results of curly red chili (Capsicum annuum L.). The research was carried out in the Greenhouse, Faculty of Mathematics and Natural Sciences, State University of Medan in March 2018 to September 2018. The parameters used in this study were the height of the stem, number of branches, number of leaves, age of appearance of flowers, number of flower, number of fruits and fruit weight. This study used a completely randomized design (CRD) with 4 treatments and 6 replications. The treatment used was treatment A (0 ml/L), treatment B (300 ml/L), treatment C (400 ml/L) and treatment D (500 ml/L). Statistical tests were carried out using SPSS 21. The results in this research were liquid organic fertilizer of Banana Var.Raja skin waste having
Nitrogen nutrient content of 0.10%, P2O5 of 0.12%, C-Organic of 0.73 % and the C / N ratio of 7.30, the lowest dose of organic fertilizer from Banana Var.Raja skin waste (300 ml/L) was not significantly different from the control while at a dose of 400 ml/L and 500 ml/L decreased yield of
curly red chili (Capsicum annuum L.) and there is no optimal dose of organic fertilizer liquid from Banana Var.Raja leather waste for stem height, number of branches, number of leaves, the age of the rise of flowers, flower number, fruit number and fruit weight of curly red chili (Capsicum annuum L.).
