Interaction of media and wood vinegar on the growth of sugar wood (Aphanamixis polystachya) seedling in the nursery Available to Purchase

Sugar wood (Aphanamixis polystachya) is a plant from the Meliaceae family that has many benefits such as medicine. The sugar wood distribution area covers China, India and South East Asia. The exploitation of sugar wood from nature will lead to scarcity and extinction. Maintaining the sustainability of sugar wood can be done through nursery and planting activities. The growth of seedlings requires appropriate planting media and fertilizers. The planting media is a factor that affecting plant seeds growth. wood vinegar is an organic compound that is suitable for use as fertilizer to support the availability of nutrients in the planting media. This study aims to obtain the interaction of media and wood vinegar that can be used to increase the growth of sugar wood seedlings in the nursery. The research experiment used a factorial completely randomized design with 2 factors, media and wood vinegar with 3 replications. The media used were: soil (control), soil + rice husk (1:1), and soil + charcoal (1:1). Wood vinegar application used was 1% and control (0%). The combination of media and wood vinegar were signifanctly impacted on the growth performances of sugar wood (A. polystachya) seedlings (height, diameter, root dry weight, and shoot root ratio) in the nursery. The best interaction of media soil + rice husk (1:1) and wood vinegar with a concentration of 1% is significant to improve the growth performance of A. polystachya seedling.
