Abstract

Research entitled "The Effect of Red Provit and Agrimore Fertilizer Regimes on the Quality of Acacia (Acacia crassicarpa) Seedlings in the Acclimatization House Area (AHA)" was carried out at Kerinci Central Nursery I West, PT Riau Andalan Pulp and Paper, Pangkalan Kerinci, Pelalawan Regency, Province Riau. This research has been carried out for approximately two months, starting from April to May 2024. This research aims to determine the interaction and main effects of Red Provit and Agrimore fertilizers on the growth of Acacia (Acacia crassicarpa) in the Acclimatization House Area (AHA). The research used a completely randomized factorial design consisting of two factors. The first factor is the dose of Red Provit fertilizer consisting of 3 levels, namely: 0, 2, 4g per liter of water and the second factor is the dose of Agrimore fertilizer consisting of 3 levels, namely: 0, 2, 4g per liter of water. The parameter observed is the increase in height plants, increase in stem diameter, increase in root compactness percentage, number of seedling survival percentages and total percentage of grade data. The data was analyzed statistically and continued with the BNJ test at the 5% level. The results showed that the interaction effect of Red Provit and Agrimore fertilizers was significant on all observed parameters. The best treatment is at a dose of Red Provit 4 g per liter of water and Agrimore fertilizer 4 g per liter of water. The main effect of Red Provit fertilizer is significant on all observed parameters. The best treatment is at a dose of 4 g per liter of water. The main effect of Agrimore fertilizer is significant on all observed parameters. The best treatment is at a dose of 4 g per liter of water.
