Potential of Immature Coconut Water and Cow Urine on the Growth of Palm Oil Seedlings in Pre-Nursery

This study aims to recognize the potential of immature coconut water and cow urine that have been fermented naturally on the growth of palm oil seedlings in the pre-nursery. This study used an experimental method with a factorial randomized block design with two repetitions. The first factor was the concentration of immature coconut water which consisted of 4 levels, namely 0 ml (K0), 10 ml (K1), 20 ml (K2), and 40 ml (K3). The second factor was cow urine with the levels of 0.0 (U0), 10 ml (U1), 20 ml (U2), and 40 ml (U3). The data were analyzed by using analysis of variance, followed by Duncan's Multiple Range Test. The results showed that the application of immature coconut water and naturally fermented cow urine significantly affected the growth (seedling height, leaf length, stem diameter, primary root length, fresh weight, dry weight) of oil palm seedlings at the pre-nursery stage, except for the growth in number of leaves and number of primary root. The combined application of 40 ml of coconut water and 20 ml of cow urine (K3U2) significantly increased the highest growth (seedlings height, leaf length, stem diameter, and fresh weight) of oil palm seedlings at the pre-nursery.
