Abstract

. The purpose of the study was to determine the interaction and main effects of Gamal Leaf POC and Organic NPK on the growth and production of cabbage. . This study used a factorial 4x4 Completely Randomized Design (CRD) consisting of two factors, namely Gamal Leaf POC factor with 4 treatment levels of 0.25 ml/l water, 50 ml/l water and 75 ml/l water and Organic NPK fertilizer factor with 4 treatment levels 0, 7.5 g/plant, 15 g/plant and 22.5 g/plant. Parameters observed were number of leaves, age of shoot emergence, age of harvest, diameter of shoots, fresh weight of shoots, and root length. The data from the observations of each treatment were statistically analyzed and continued with the further test of Honest Significant Difference (BNJ) at the 5% level. Based on the results of the research that has been carried out, it can be concluded that: The interaction of Gamal Leaf POC and Organic NPK affects the number of leaves, age of shoot emergence, harvest age, and root length. The best treatment was the combination of POC Gamal Leaf 75 ml/l water and Organic NPK 22.5 g/plant. The main effect of Gamal Leaf POC was real on all observation parameters with the best treatment being the concentration of 75 ml/l water. The main effect of real Organic NPK on all observation parameters with the best treatment was the dose of 22.5 g/plant.
