Cocoa is one of the estate crop whose role is quite important for the national economy, particularly as a provider of employment,  income and foreign exchange. The high export opportunities of cocoa beans has not been followed by the production of cocoa beans in Indonesian. The production of dried cacao  beans in Indonesia is still low. The low productivity of seeds generally caused by  Cherelle wilt of cacao. Wilting occurs due to inability of the cherelle to compete with the other cherelle in absorbing nutrients. Fertilization is an effort to maintain and fulfill the nutrients in the plants. This research is aimed to assess the effect of fertilization using cocoa pod husk and NPK tablets fertilization on cocoa crop yields. This experiment was conducted at PT. PP. Bajabang Indonesia, Cipeundeuy, West Bandung regency from December 2016 to March 2017. The experiment was conducted using a Simple Randomized Block Design that consists 10 treatments: control, single N, P, K fertilizer  297 g/tree, cocoa pod husk  9 kg/tree, cocoa pod husk  9 kg/tree + single N, P, K fertilizer 297 g/tree, cocoa pod husk 18 kg/tree + single N, P, K fertilizer  297 g/tree, cocoa pod husk 9 kg/tree  + NPK tablet fertilizer 20 tablets/tree, NPK tablet fertilizer 20 tablets/tree,  cocoa pod husk  9 kg/tree  +  NPK tablet fertilizer 10 tablets/tree, cocoa pod husk 18 kg/tree + NPK tablet fertilizer 20 tablets/ tree, cocoa pod husk 18 kg/ tree + NPK tablet fertilizer 10 tablets/tree. The result of experiment showed that there was an influence of cocoa pod husk and NPK tablet fertilizer on cocoa fruit weight at 12 MSP, that is cocoa pod husk 9 kg/tree  +  NPK  tablet fertilizer 20  tablets/tree.  Number of cherelle wilted  at 12 MSP with cocoa pod  husk 9 kg/tree  +  NPK  tablet fertilizer 20  tablets/tree.

This study aimed to study the profile of starch content in cocoa leaf and phytoalexin production based on GC-MS analysis at several stages of VSD pathogen infection. Research was conducted on January – October 2015 at Kaliwining Experimental Field, Indonesian Coffee and Cocoa Research Institute, Jember, East Java. The research was designed based on a Completely Randomized Block Design with two factors with three replications. The first factor was clone, i.e. the resistant clone (Scavina 6) and susceptible (TSH 858) to VSD infection. The second factor was the level of O. theobromae infection, i.e. pre-infection, early infection, and late infection. Starch catabolism revealed during Vascular Streak Dieback infections in Cacao. Starch content in Sca 6 (resistant clone) in late infection decreased 24,33 % than healthy condition (no infection), however, starch content in TSH 858 (succeptible clone) in late infection decreased only 9,63 % than healthy condition (no infection). This indicated that starch catabolism rate on resistant clone was higher than susceptible clone. Some secondary metabolites releases under Vascular Streak Dieback i.e. I-limonene, eugenol and coumaran. Scavina 6 (resistant clone) had higher concentration of eugenol and coumaran than TSH 858 (susceptible clone). I-limonene compound, TSH 858 (Susceptible clone) had higher concentration than Scavina 6. I-Limonene concentration increased in lined with the severity of pathogen infection. There were an negative correlation between starch content with contentration of I-limonene (R= - 0,74), concentration of Eugenol (R= - 0,44), and contentration of Coumaran.

Several factors that affect production of cocoa (Theobroma cacao L.), one of which is the quality of seedlings. The quality of seedlings is affected by the type of clones and the composition of the planting media. This study aims to obtain the influence of clone types and types of manure, as well as the interaction between clone types and types of manure on the growth of cocoa seedlings. The study was conducted in the field of practices and Laboratory of the State Polytechnic of Lampung, in January to June 2017. The method used was a Randomized Block Design (RBD) factorial pattern consisting of two factors. The first factor is the type of clone consisting of three levels, namely K1 = TSH clone 858, K2 = ICS 60, and K3 = TSH 908. The second factor consists of four levels namely P0 = Control, P1 = Chicken Manure, P2 = Cow Manure , and P3 = Goat Manure. The results showed that the use of TSH 858, ICS 60, and TSH 908 clones had the same effect on all observed variables. However, the use of manure has a significant effect on each variable, but the amount of leaf chlorophyll is relatively the same between clone types and types of manure, there are interactions between clone types and types of manure.

Cocoa was established at Owena in the Southwestern part of Nigeria using four planting distances of 3.0 x 3.0 m, 2.5 x 2.5 m, 2.0 x 2.0 m and 1.5 x 1.5 m which was laid out in a Complete Randomized Block Design with four replicates. Data was collected between August 2014 and May 2017 on the survival count, morphological parameters (plant height, stem circumference and number of branches), number of cocoa pods and dry cocoa beans weight to determine the vigour and yield performance of cocoa plants. The results revealed significant differences (p=0.05) between treatments based on the plant spacing. While cocoa plants on 3.0 x 3.0 m treatment had significantly higher height, stem circumference and number of branches than those on 2.0 x 2.0 m and 1.5 x 1.5 m from 12 months after transplanting. The number of cocoa pods and weight of dry cocoa beans for individual cocoa trees followed the same trend with their vigour performance. However, the total yield per hectare showed significantly higher value (p=0.05) for cocoa under close spacing than the recommended traditional 3.0 x 3.0 m with low population density planting. With the present results, we recommend that cocoa farmers in Nigeria should explore a high planting density system during the first few years of establishment while the trees surpluses should be eliminated once the plants’ canopy spread are becoming too interwoven.
