Abstract

This study aims to determine the response of growth and production of black soybean (Glycine soja (L) Merril) to tofu dregs bokashi and POC GDM. This research was conducted at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City for four months, starting from March to June 2021. This study used a Factorial Completely Randomized Design (CRD) consisting of two factors. The first factor was the dose of tofu dregs bokashi which consisted of 4 levels, namely 0, 1,000, 1,500 and 2,000 g/plot and the second factor was the POC GDM concentration which consisted of 4 levels, namely 0, 4, 8 and 12 ml/l water. Parameters observed were plant height, number of main branches, flowering age, harvest age, number of pods per plant, fresh weight of pods per plant, dry weight of pods per plant, percentage of full pods, weight of 100 seeds and dry weight of seeds per plot. The data were analyzed statistically and continued with the BNJ test at the 5% level. The results showed that the interaction effect of tofu dregs bokashi and GDM POC was significant on the parameters of plant height, number of main branches, number of pods per plant, fresh weight of pods per plant, dry weight of pods per plant, percentage of full pods, weight of 100 seeds and dry weight of seeds per plot. The best treatment dose of bokashi tofu dregs was 2,000 g/plot and the POC GDM concentration was 12 ml/l water. The main effect of tofu dregs bokashi was real on all observation parameters. The best treatment at a dose of 2,000 g/plot. The main effect of POC GDM is real on all observation parameters. The best treatment at a concentration of 12 ml/l water.
