Abstract

This study aims to determine the interaction and principal effects of Organic NPK and Gandasil-D on the growth and yield of mustard greens (Brassica juncea L.). This research was conducted at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City for two months, starting from December 2022 to January 2023. This research used a Completely Randomized Design (CRD) Factorial which consisted of two factors. The first factor is the dose of Organic NPK which consists of 4 levels, namely 0; 7.5; 15 and 22.5 grams per plant and the second factor is the concentration of Gandasil D which consists of 4 levels, namely 0; 2; 4 and 6 grams per liter of water. Parameters observed were plant height, number of leaves per plant, economic wet weight, dry weight per plant and root volume. The data were analyzed statistically and continued with the BNJ test at the 5% level. The results showed that the interaction effect of Organic NPK and Gandasil D was significant on the parameters of the number of leaves per plant, economic wet weight, dry weight per plant and root volume. The best treatment was the organic NPK dosage of 22.5 grams per plant and the concentration of gandasil D was 6 grams per liter of water. The main effect of real organic NPK on all observation parameters. The best treatment at a dose of 22.5 grams per plant. The main effect of Gandasil D is significant on all observation parameters. The best treatment at a concentration of 6 grams per liter of water.
