Abstract

The use of POC paitan (Tithonia diversifolia L.) and Gandasil-D fertilizer in the cultivation of green mustard greens (Brassica juncea L.) hydroponically aims to determine the interaction and main effects of the concentration of POC paitan and the dosage of Gandasil-D fertilizer in the cultivation of green mustard greens (Brassica juncea L. .). This research was carried out at the Integrated Experimental Agriculture Unit, Faculty of Agriculture, Riau Islamic University, Jalan Kasang Kulim Teropong, Kubang Raya Village, Siak Hulu District, Kampar Regency. The research was carried out from June-July 2024. The design used in this research was a factorial Split Plot Design (RPT) with two factors. The first factor is POC-paitan consisting of 4 treatment levels, namely 0, 300, 600 and 900 ppm and the second factor is the dose of Gandasil-D fertilizer consisting of 4 treatment levels, namely without, 0, 5, 10 and 15 g/l, so there are 16 combination of treatments with 3 replications means there are 48 experimental units. The parameters observed were plant height, number of leaves, leaf area, economic wet weight of the plant, dry weight, root volume and leaf chlorophyll. The observation data was analyzed statistically and continued with the BNJ test at the 5% level. The results of the research showed that the interaction and main effect of the POC-paitan dose and the Gandasil-D fertilizer dose had a significant effect on plant height, number of leaves, dry weight, root volume, leaf chlorophyll and had no significant effect on the parameters of leaf area and economic wet weight of the plant. The best treatment is a combination of POC-paitan fertilizer 900 ppm and gandasil-D 15 g/l
