Some types of varieties that are often developed are green spinach. Green spinach has good benefits for the body because it is a source of calcium, vitamin A, vitamin E, vitamin C, fiber and also beta-carotene. Spinach is good for digestion and strengthens muscles and has many benefits for treating diseases. The purpose of the study was to determine the effect of giving various combinations of doses of liquid organic fertilizer from rabbit urine with goat manure on spinach growth. Planting superior varieties is one way to increase the growth of green spinach plants. The study was conducted in a greenhouse in Karangpari Village, Bantarkawung District, Brebes Regency, Central Java. The study began in September to November 2022. This study used the Randomized Block Design (RAK) method consisting of 2 factors, namely liquid organic fertilizer from rabbit urine and goat manure. Each factor consists of 5 levels of fertilizer dose treatment. The first factor, the dose of liquid organic fertilizer of rabbit urine, namely 0 ml/l (U0), 7.5 ml/l (U1), 17.5 ml/l (U2), 27.5 ml/l (U3), 37.5 ml/l (U4) and the second factor, the dose of goat manure, namely control (K0), 40 grams (K1), 64 grams (K2), 80 grams (K3), 108 grams (K4) with each combination of treatments repeated 3 times. The variables observed in this study were plant height, number of leaves, leaf area, stem diameter, leaf shoots, plant wet weight, plant dry weight, root wet weight, root dry weight. Observation data were analyzed using Analysis of Variance (Anova). The results of the study of the combination of doses of liquid organic fertilizer of rabbit urine with goat manure did not significantly affect the growth of green spinach for all observation variables. The best combination in the treatments U1K4, U2K2 and U0K4 had the best value although not significantly different compared to the control.</em></p> Deki Kurniawan Ratna Dwi Hirma Windriyati Rifqi Adisonda Copyright (c) 2025 Jurnal Agroteknologi Universitas Nahdlatul Ulama Purwokerto 2025-08-17 2025-08-17 1 2 1 11
