Abstract

This study aims to determine the effect of the interaction and main effect of POC from leguminasae and NPK Grower 15-09-20 on the growth and production of Cilembu sweet potato. This research was carried out at the Experimental Garden of the Faculty of Agriculture, Islamic University of Riau, Jalan Kaharuddin Nasution Km 11 No. 113, Perhentian Marpoyan, Air Cold Village, Bukit Raya District, Pekanbaru City for 5 months starting September 2021-January 2022. This study used a factorial Completely Randomized Design (CRD) consisting of two factors. The first factor was leguminasae POC consisting of 4 levels, namely without treatment, peanut POC, lamtoro and trambesi. The second factor was NPK Grower 15-09-20 consisting of 4 levels, namely without treatment, 5, 10 and 15 g/plant, so that 16 treatment combinations were obtained. The treatment combination was repeated 3 times, so there were 48 experimental units. Parameters observed were tuber diameter, tuber length, tuber number per plant, tuber weight per plant, tuber weight per tuber and brix test. Data were analyzed statistically and continued with BNJ level of 5%. The results showed that the interaction of POC leguminasae and NPK Grower was significant on the parameters of tuber diameter, tuber length, number of tubers per plant, tuber weight per plant and tuber weight per tuber. The best treatment is POC trembesi 100 ml/l water and NPK Grower 15 g/plant. The main effect of POC leguminasae is significant on all observation parameters. The best treatment for trembesi POC is 100 ml/l water. The main effect of NPK Grower is real on all observation parameters. The best treatment dose is 15 g/plant.
