Abstract

This study aimed to determine the effect of giving liquid tofu fertilizer to the growth and yield of red spinach plants (Alternanteraamoenavoss) with floating raft hydroponic techniques. Research on red spinach growth parameters was carried out at Horti Park Lampung. The method used in this study was Complete Random Design (CRD) consisting of 4 concentration P0 (0% AB Mix), P1 (30%), P2 (45%) and P3 (60%) and 3 replications. The study was conducted for 4 weeks. Measurements and observations are carried out 4 times, i.e. every 1 week. The parameters measured were stem height, number of leaves, leaf width, root length. Then, the data analysis was performed using One Way ANOVA on SPSS 17, and register later with the LDS test at the level of 5% significance. The results showed that tofu wastewater available at P3 maintenance (60%) was significantly different from other treatments, and at the same time discussed liquid waste which was known at the time of preparation of P1 (30%) because, it did not depend on nutrients contained in inside, so it causes less growth, compared to the implementation of P0 (0%), P2 (45%) and P3 (60%).
