Abstract
This research was conducted in Meurandeh Dayah Village, Langsa Lama District, Langsa City. This study aims to determine the effect of planting media and soaking time of seeds in young coconut water and the interaction of the two treatments on the growth parameters of cocoa seedlings. This study used a factorial randomized block design (RAK) consisting of 2 factors, namely the first factor was planting medium (M) topsoil layer (M1), topsoil layer soil + 2:1 manure (M2), topsoil layer soil + manure. + coconut husk 2:1:1 (M3), topsoil layer + manure + coconut husk + rice husk charcoal 2:2:1:1 (M4). The second factor was the soaking time of the seeds in young coconut water (K), which consisted of no soaking (K0), 3 hours (K1), 6 hours (K2) and 9 hours (K3). The results showed that the effect of planting media and time of immersion of seeds in young coconut water. topsoil layer + manure + coconut husk + rice husk charcoal gave the best growth on the parameters of seedling height, number of leaves, leaf length, leaf width and root length. Then soaking with young coconut water for 9 hours of growth is better than other immersion or without soaking.
