PENGARUH PEMBERIAN PUPUK ORGANIK LIMBAH CAIR TAHU TERHADAP PERTUMBUHAN SEMAI KEMIRI (Aleurites moluccana Willd)

Abstract

The chandlenut (Aleurites moluccana Willd.), is one of the multipurpose trees that is widely cultivated in the world. Cultivation of candlenut seedlings requires maintenance and fertilizer application, one of the fertilizers used is liquid organic fertilizer made from tofu liquid waste. The study was carried out from October 2020 to January 2021, at the permanent nursery of the Palu Poso BPDAS, this study used a Completely Randomized Design (CRD) method consisting of 5 treatments, namely P0 = 0 ml POC / l solution (control), P1 = 100 ml POC /l solution, P2 = 200 ml POC/l solution, P3 = 300 ml POC/l solution, and P4 = 400 ml POC/l solution. The five treatments were repeated 10 times each, the total sample was 50 experimental units. Parameters observed were increase in height, diameter, and number of leaves. Data analysis used was variance (F test). If analysis of variance showed that the treatment had a significant effect, it would be continued with a further test, namely the 5% BNT test. The results showed that the effect of giving organic tofu liquid waste to the growth of candlenut seedlings with different doses gave no significant effect on the increase in stem height and stem diameter, but had a significant effect on the increase in the number of leaves on the candlenut seedlings. The best treatment in this study namely P2 with a dose of 200 ml POC / l solution which gives an average increase in the number of leaves of 2.24 leaves
