PENGARUH PEMBERIAN AMPAS TEH TERHADAP PERTUMBUHAN SEMAI MAHONI (Swietenia mahagoni Jacq)
Abstract
Máhoni (Swietenia macriphylla) is a plant that is spread throughout Indonesia. This plant has a fairly high ecological and economic value. Therefore, warm mahogany has the potential to be developed. This study used a completely randomized design (CRD) consisting of five levels of treatment, namely KO = No treatment (control), K1 = tea dregs 60g/polybag, K2 = tea dregs 120g/polybag, K3 = tea dregs 180g/polybag and K4 = Tea dregs 240g/polybag. Of the four treatment levels, each was repeated 10 times so that a total of 50 experimental units were used. Observational parameters used in this study consisted of four namely height, diameter, number of leaves and the robustness of seedlings. Analysis of variance was carried out to determine the effect of treatment on the observation parameters, at a significant level of 5%, if the calculated F is greater than the F table 5%, then a further test of Honest Significant Difference (BNJ) is carried out at a significant level of 5%. The provision of tea dregs had a significant effect on the growth of mahogany (Swietenia mahagoni Jacq) seedlings aged 12 weeks after planting. Giving tea dregs 240 g/polybag gave the best effect on the growth of mahogany seedlings on the parameters of height, diameter and number of leaves, namely an average height of 7.06 cm, an average diameter of 1.49 mm and an average number of leaves of 10.7 compared to other treatments.
