Abstract

The aim of the study was to determine the growth response of Pakcoy mustard plants to the interaction and main treatment of Ketapang leaf bokashi and NPK 16:16:16. This research has been carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Jalan Kaharuddin Nasution Km 11, Air Cold Village, Bukit Raya District, Pekanbaru City. This research was carried out for 2 months starting from March to April 2022. The study used a two-factor Completely Randomized Design (CRD) namely the dose of Bokashi Leaves Ketapang (B) consisting of 4 levels, namely 0, 30, 60, and 90 g/plant and the second factor was the dose of NPK 16:16:16 (N) consisting of 4 levels, namely 0, 0.6, 1.2, and 1.8 g/plant so that there were 16 treatment combinations with 3 replications, so there were 48 experimental units. Parameters observed were plant height, number of leaves, leaf width, plant wet weight, and economic wet weight. The data were analyzed statistically and continued with the honest significant difference test (BNJ) at the level of 5%. From the results of the research that has been carried out, it can be concluded that the interaction effect of ketapang leaf bokashi and NPK 16:16:16 significantly affected all observation parameters except plant height and leaf width. The best treatment was the combination of bokashi leaf ketapang 90 g/plant and NPK 16:16:16 1.8 g/plant (B3N3). The main treatment of ketapang leaf bokashi had a significant effect on all observation parameters. The best treatment of ketapang leaf bokashi 90 g/plant (B3). The main treatment of NPK 16:16:16 had a significant effect on all observation parameters. The best treatment at NPK 16:16:16 1.8 g/plant (N3).
