Abstract

The purpose of this study is to determine the effect of interaction and the main organic NPK fertilizer and superior plant hormones in cabbage plants flower. This research was carried out for 3 months in the Experimental Garden Faculty of Agriculture, Riau Islamic University, starting from May 2021 until with August 2021. The design in this study uses Completely Randomized Factorial Design consisting of two factors. which factor the first is Organic NPK fertilizer (N) which consists of four dose levels namely 0, 6, 9, and 12 g/plant, then the second factor is the hormone concentration superior plants (H) with 4 concentration levels, namely 0, 1, 2, and 3 ml/l water. The parameters observed in this study were plant height, number of leaves, the age at which the crop is formed, the age at harvest, the diameter of the crop, the economic wet weight, and root volume. Statistical analysis data and if f count is greater than f table followed by Honest Real Test (BNJ) at the level of 5%. Research result shows that the interaction of organic NPK fertilizer and plant hormones is superior significant effect on plant height, harvest age, crop diameter, weight wet economical, and root volume. Combination The best treatment is on dose Organic NPK fertilizer 9 g/plant and superior plant hormone concentration 2 ml/l water (N3H2). The main effect of organic NPK fertilizer is significant for all parameters and the best treatment dose of Organic NPK fertilizer is 12 g/plant (N3). The main effect of superior plant hormone concentrations has a significant effect on all parameters and the best treatment is the concentration of 3 ml/l water (H3).
