Abstract
A study has been carried out to determine the effects of different sources of agriculture wastes and types of clones on the survival rates of cocoa grafted seedlings in nursery. The treatments listed as: T1: - conventional fertilizer (5 gram / NPK Yellow 12:12:6:4) for cocoa nursery standard, T2: – Chicken manure (CHM), 1.8:1.6:4 (33 gram), T3 – Cocoa pod husk (CPH), 1.7:0.04:3.1 (35 gram), T4 – Cow manure (CM), 1.9:0.9:2.9 (31 gram) and T5 – Empty fruit bunch (EFB), 1.7:0.2:2.2 (35 gram) which applied once a month, with two selected clones; PBC 123 and KKM 22. Design for the trial was Random Complete Block Design (RCBD) in three replicates with two factors studied; Fertilizers and Clones. From the result, it can be concluded that clone KKM 22 has the highest rate of survivability in comparing with clone PBC 123, while all fertilizer treatments have given none effect on the success rate of survivability of the grafted seedlings. Thus, it can be concluded that clone was correlated with success rate of survivability of grafted seedling whereas, fertilizer treatment is merely for growth and development of the cocoa grafted seedlings in nursery.
