GROWTH RESPONSE OF PAGODA MUSTARD PLANTS (Brassica narinosa L.) TO THE APPLICATION OF JELLYFISH LIQUID ORGANIC FERTILIZER

Excessive use of chemical fertilizers can reduce soil quality and fertility, and is not environmentally friendly. One organic fertilizer that can overcome the problem of agricultural land damage is liquid organic fertilizer. Liquid organic fertilizer that can be used as fertilizer is jellyfish marine biota. This research aims to determine the right dose of jellyfish liquid organic fertilizer to produce high growth and yield of pagoda mustard plants.This research used a non-factorial Randomized Group Design (RAK) consisting of four treatments. Each treatment was repeated six times as follows: P0: Urea 150 kg/ha (control); P1: jellyfish POC 5 ml/l; P2: jellyfish POC 10 ml/l; P3: POC jellyfish 15 ml/l. Data obtained from the research were analyzed using analysis of variance (F test), if there was a real effect, was with the BNT test at the 5% level. The results showed that applying jellyfish POC fertilizer could increase total plant dry weight, leaf area index, net assimilation rate and plant growth rate. Treatment of jellyfish POC with a dose of 15 ml/l and treatment of 10 ml/l with the addition of 150 kg of urea fertilizer were treatments with higher results.
