INTERAKSI PUPUK LIMBAH IKAN PADAT DENGAN PUPUK KIESERITE TERHADAP PERTUMBUHAN BIBIT PINANG (Areca catechu.L)
Abstract
Areca nut (Areca catechu L.) is a type of palm, which is mainly grown for its seeds. Areca nut has many uses, including being useful as an ingredient in the pharmaceutical industry, cosmetics, coloring material in the textile industry and also for consumption, known as a mixture when people eat betel, in addition to gambier and lime. Areca nut is a commodity for export trade from Indonesia which is directed to South Asian countries such as India, Pakistan, Bangladesh, or Nepal. The main betel nut exporting countries are Indonesia, Thailand, Malaysia, Singapore and Myanmar. Ministry of Agriculture (2013). Fish waste has the potential to be used as organic fertilizer, considering that fish waste contains high protein. Research by Syafrani, Susi and Sari (2016) reported that fish waste organic fertilizer contains C-organic, Nitrogen, Phosphorus and Potassium. In addition, fish waste also contains other elements although in low composition. Kieserite fertilizer is a single fertilizer containing magnesium and sulfur. Kieserite fertilizer is also known as magnesium sulfate fertilizer. Kieserite fertilizer has a function to increase the pH of the soil, so that the soil that was previously acidic will increase its pH. In addition to increasing soil pH, it can also increase the absorption of K and P nutrients by plants. Element S contained in kieserite fertilizer for crops. The results of the study concluded that the application of fish waste solid fertilizer and cliserite fertilizer and their interactions had a significant effect on the growth of areca nut seedlings on all parameters, namely plant height, number of leaves, stem diameter, leaf area and root architecture, while the best interaction was in the L2K2 treatment. namely the provision of solid fish waste fertilizer at a dose of 30 grams for planting and giving cliserite fertilizer at a dose of 2 grams for planting Keywords: Areca nut, organic fertilizer, Fish solid waste
