The research was conducted at the organic fertilizer manufacturing site 'Minak Jinggo' which is located in Sumberbaru Village, Singojuruh District, Banyuwangi Regency and continued the analysis at the Soil Science Study Program Laboratory, Faculty of Agriculture, University of Jember. In the first coronation design using a Complete Randomized Design (RAL) with one factorial and 7 treatments. Compost content testing was carried out which included analysis of measuring pH, N, P. K, C-Organic and C / N ratio of compost. Compost results with time and content in accordance with Kepmentan No. 261 of 2019 were then designed an effect test experiment on mustard pakcoy plants with 2 factorials, namely the compost used and the dosage.

This study aims to determine the effect of the seed length of spring onion seeds and rabbit urine fermentation on the growth of spring onion. This study used a factorial randomized block design consisting of two factors and three replications. The first factor includes cutting the seeds, namely (P1) 10 cm, (P2) 15 cm, and (P3) 20 cm.
