Correlation Analysis between LOF Dosage from Cassava Peel with Stem Height, Number of Leaves, and Leaf Width on Cocoa Seedlings (Theobroma cacao L.)

This study aims to determine the correlation analysis of the liquid organic fertilizer (LOF) dose of cassava peel with stem height, number of leaves, and leaf width on Cocoa Seedlings (Theobroma cacao L.). This study was conducted in an experimental garden with a controlled environment managed by the Plantation Management Study Program at the Politeknik Indonesia Venezuela, Aceh Besar Regency. Bivariate correlation analysis tests were conducted to examine the relationship between the LOF dose and growth parameters of stem height, number of leaves, and leaf width. The results of the bivariate correlation analysis showed that the administration of LOF 50-150 mL correlated with plant height and the number of leaves. The variable number of leaves of Cocoa plants was closely related to the variable LOF 200 ml. This is because LOF contains macronutrients (such as N, P, K) and micronutrients (Fe, Zn, Mn, Cu) as well as bioactive compounds such as amino acids, humic acid, and growth hormones (auxins, cytokinins, and gibberellins). Several doses of LOF made from cassava peels showed a positive correlation with the height and number of leaves of cocoa plants. However, there was no correlation between LOF and leaf diameter.
