Response of Cocoa (Theobroma cacao L.) Seedlings to the Application of Various Types of Manure on Latosol
Keywords:
cocoa, manure, latosol soil, seedling growthAbstract
This study aimed to determine the effect of various types of manure on the growth of cocoa (Theobroma cacao L.) seedlings on latosol soil media. The research was conducted in August 2025 at the Experimental Farm of the State Polytechnic of Agriculture Payakumbuh using a Completely Randomized Design (CRD) with four treatments and six replications: P1 = cow manure, P2 = goat manure, P3 = chicken manure, and P4 = duck manure. Parameters observed included seedling height, stem diameter, number of leaves, fresh weight, and dry weight. Data were analyzed using ANOVA followed by Duncan’s New Multiple Range Test (DNMRT) at 5% significance level. The results showed that manure application significantly affected seedling height but had no significant effect on stem diameter and number of leaves. Goat manure (P2) resulted in the highest fresh and dry weights. Therefore, goat manure is recommended as the best organic fertilizer source for cocoa seedling growth on latosol soil.
