Abstract

This study aims to determine and study the effect of liquid organic fertilizer, Actinomycetes and mycorrhizae on the growth of cocoa seedlings. This research was conducted at the Laboratory of Bioscience and Plant Reproduction Biotechnology, Department of Cultivation, Faculty of Agriculture, Hasanuddin University and Teaching Farm, Faculty of Agriculture, Hasanuddin University from January to June 2022. The study was conducted using a Split Plot Design (RPT). The main plot was liquid organic fertilizer consisting of four levels, namely control, 5 mL/L, 10 mL/L and 15 mL/L. Subplots were Actinomycetes and mycorrhizae consisting of four levels, namely control, 105 CFU/mL Actinomycetes + 10 g mycorrhizae, 106 CFU/mL Actinomycetes + 15 g mycorrhizae and 107 CFU/mL Actinomycetes + 20 g mycorrhizae. The results showed that there was no interaction between the treatment of liquid organic fertilizer, Actinomycetes and mycorrhizae on each parameter of observation. Treating 10 mL/L of liquid organic fertilizer resulted in the longest root length (36.14 cm) and the largest root volume (11.26 ml). Treatment of 107 CFU/mL Actinomycetes + 20 g mycorrhizae resulted in the longest root length (34.33 cm) and the largest root volume (10.83 mL).
