Respon Pemberian Pupuk Organik Cair Kelinci dan Pupuk Hayati Cair terhadap Pertumbuhan dan Produksi Tanaman Pakcoy (Brassica rapa L.) serta Pemanfaatannya sebagai Leaflet

Abstract

This research was conducted from February to April 2023 at the Green House of Biology Education, University of Jember. This study aims to determine the response of rabbit urine POC and liquid biological fertilizer and to obtain the optimal concentration of each treatment and treatment combination. This research was conducted experimentally with a two-factorial completely randomized design (CRD) method. The plant samples in this study amounted to 48 plants from 16 treatment combinations and each treatment was repeated 3 times. Parameters in this study include plant height, plant height rate, number of leaves, fresh weight, production weight, harvest index, and dry weight and make qualitative observations. The research data were then analyzed using ANOVA test with a significant level of 5% using the SPSS program followed by Duncan's Multiple Range Test (DMRT) test conducted with a confidence level of 95%. The results showed that there was an interaction in the combination of rabbit urine POC and liquid biological fertilizer on the growth and production of pakcoy (Brassica rapa L.) plants in the parameters of plant height, number of leaves, fresh weight, and dry weight. The optimal concentration combination of rabbit urine POC and liquid biological fertilizer for the growth and production of pakcoy (Brassica rapa L.) is 40 mL/L rabbit urine POC and 10 mL/L liquid biological fertilizer (K2P2). The results of the study were used as educational media products in the form of leaflets that were made available. The results of the study were used as educational media products in the form of leaflets which were validated and received an average score of 82.5%, which is feasible to use as an information source
