Effect of the application of chicken manure compost tea on the growth of certified cocoa (Theobroma cacao L.) seedlings

Abstract

This study aims to determine the best concentration of compost tea on various cocoa seedlings. The research was conducted in Sudiang Village, Makassar City, South Sulawesi, from August to December 2019. The experiment was set using a 2-factor factorial design in a randomized block design (RBD) as the environmental design. The first factor was the type of cocoa varieties which consists of three levels, namely Sulawesi 1, Sulawesi 2, and MCC 02. The second factor was the compost tea which consists of four levels, namely control (0 mL/L water), 50 mL/L water, 100 mL/L water, and 150 mL/L water. The results show that MCC 02 cocoa seedlings applied with compost tea fertilization of 100 mL/L of water showed the best response on the parameters of the number of leaves, stem diameter, fresh root weight, root dry weight and leaf chlorophyll index, chlorophyll A, chlorophyll. B and total chlorophyll.
