PENGARUH PEMBERIAN AMPAS DAN AIR TEH TERHADAP PERTUMBUHAN SEMAI DURIAN (Durio Zibethinus Murr

This research was conducted for three months from January to April 2022 at the BPDASHL Palu – Poso Permanent Nursery, Tadulako University, Palu, Central Sulawesi. This research used a Factorial Complete Randomized Design method. The first factor, namely: A1=100g tea dregs, A2=200g tea dregs, A3=300g tea dregs. The second factor namely: B0 = without tea water, B1= pouring 100ml of tea water every 2 weeks. The results of the analysis of variance showed that the application of tea dregs and tea water had a significant effect on the durian (Durio zibethinus Murr.) seedlings, so the BNT test was continued at the 5% level. Giving tea dregs significantly affected the parameters of height, diameter, and number of leaves. The treatment that gave the best effect was A3 = 300g tea dregs. Watering the tea water only affects the parameter of seedling diameter. The treatment that gave the best effect was B1 = 100 ml of tea water. The interaction between tea dregs and sprinkling of tea only had a significant effect on the parameters of height, diameter, and seedling firmness. The treatment interaction that gave the best effect was A3B1 = 300g tea dregs + 100ml tea water, with a height = 5.97cm, and a diameter = 0.91mm. Whereas on the value of seedling robustness, the treatment interaction that gave the best effect was A1B1 = 100g tea dregs + 100ml tea water.
