Pengaruh Kompos Daun Ketapang dan Pupuk Gromore terhadap Pertumbuhan Serta Hasil Tanaman Sawi Caisim (Brassica Juncia l)
The research entitled "The Effect of Ketapang Leaf Compost and Growmore Fertilizer on the Growth and Yield of Mustard Greens (Brassica juncea L.)", was carried out at the Experimental Garden of the Faculty of Agriculture, Islamic University of Riau, Pekanbaru from March to April 2023. The aim of this study to determine the interaction effect and the main treatment of ketapang leaf compost and Growmore on the growth and yield of caisim mustard plants. The study used a completely randomized factorial design consisting of 2 factors. The first factor is the dose of ketapang leaf compost which consists of 4 levels, namely: 0; 11.25; 22.5; 33.75 g/polybag and the second factor is the Growmore concentration which consists of 4 levels, namely: 0; 1.5; 3; 4.5g/l water. Parameters observed were plant height, number of leaves, fresh weight per plant, economic wet weight, dry weight per plant and root volume. Observational data were analyzed statistically and continued with the BNJ follow-up test with a level of 5%. The results showed that the interaction effect of ketapang leaf compost and Growmore was significant on the observed parameters of the number of leaves, fresh weight per plant, economic wet weight, dry weight per plant and root volume. The best treatment dose of ketapang leaf compost was 33.75 g/polybag and Growmore concentration was 4.5 g/l water. The main effect of ketapang leaf compost is significant on all observation parameters. The best treatment at a dose of 33.75 g/polybag. The main effect of Growmore is real on all observation parameters. The best treatment at a concentration of 4.5 g/l water.
