PERAKITAN PUPUK ALTERNATIF UNTUK BUDIDAYA SAWI PAKCOY (Brassica rapa subsp. Chinensis) DENGAN SISTEM HIDROPONIK RAKIT APUNG

Abstract

Alternative fertilizers can be a solution for hydroponically cultivated bok choy without having to use commercial fertilizers. This study aims to determine which alternative fertilizers that can be used to grow bok choy hydroponically, with no differences in growth and yield when Commercial or Standard fertilizer used. This research was conducted at the Kartini Experimental Garden, Faculty of Agriculture and Business, Satya Wacana Christian University, from December 2019 to February 2020. The experimental design used was the Randomized Complete Block (RCB), with a single treatment of 5 level factors (Standard fertilizer, Commercial fertilizer, Mas'ud fertilizer, Hermawan revised fertilizer, and Tama fertilizer). Each level included 5 replicates. Parameters observed included plant height, number of leaves, canopy fresh weight, tuber diameter, and leaf area. The data set was analyzed using analysis of variance (F test 5%). Whereas the follow-up test was carried out with the Duncan Multiple Range Test with a 95% confidence interval. The results showed that the Commercial fertilizer treatment yielded a fresh weight of 265.11 grams which was not significantly different from the Mas'ud fertilizer which was 209.52 grams. While Tama fertilizer can be used for alternative fertilizers with a yield of 153.87 grams.
