RESPON PERTUMBUHAN BERBAGAI JENIS SAYURAN PADA SISTEM NATURAL HYDROPONIC TECHNOLOGY (NHT) TERHADAP PERBEDAAN SUMBER HARA

Abstract

NHT (Natural Hydroponic Technology) is a simple hydroponic technology model environment-based and easy to apply. The purpose of this study was to determine the growth response of various vegetables planted with the NHT system against difference nutrients resources. This study used a Completely Randomized Design (CRD) with one treatment factor which is the plant nutrients resources. The nutrients resources were AB-mix fertilizer, and fish feces with different densities. Growth variables observed were plant height, number of leaves, and wet weight of vegetables. Data were analyzed statistically with ANOVA at 95% of confidence level and continued with BNT test. The results of data analysis showed that vegetables with nutrients from AB-mix fertilizer and fish feces with a density of 300 fish/ m² showed the same growth. As for vegetables with nutrients sources of fish feces with a density of 200 fish/ m² showed the lowest growth. From these results, it can be concluded that various types of vegetables provide the same growth response to AB-mix fertilizer and fish feces with density in accordance with the number of plants. From the results of this study, it is recommended that in planting various types of vegetables with the NHT system, it is better to use fish faces with a density adjusted to the number of plants so that it can reduce the cost of using fertilizer.
