Abstract

The aim of this study was to determine the interaction and main effects of coconut dregs and urea fertilizer on the growth and yield of mustard greens. This research was 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 conducted for 2 months starting from June to July 2023. The design used in this study was a factorial Completely Randomized Design (CRD) consisting of 2 factors. The first factor was the dose of coconut dregs (A) consisting of 4 levels, namely 0, 24, 48, and 72 g/plant and the second factor, namely the dose of Urea fertilizer (N) consisting of 4 treatment levels, namely 0, 0.4, 0.8, and 1.2 g/plant so that there are 16 treatment combinations with 3 replications, there are 48 experimental units. Parameters observed were plant height, number of leaves, leaf length, leaf width, fresh plant weight, and economic wet weight. The data were analyzed statistically and continued with the honest significant difference test (BNJ) at the 5% level. From the results of the research that has been carried out, it can be concluded that the interaction effect of coconut dregs and urea has a significant effect on all observation parameters except the number of leaves. The best treatment was the combination of 72 g/plant coconut dregs and 1.2 g/plant urea. The main treatment of coconut dregs waste has a significant effect on all observation parameters with the best dose of 72 g/plant. The main treatment of urea had a significant effect on all observed parameters with the best dose of 1.2 g/plant.
