Abstract

Soil fertility level improvement in an environmentally friendlier way has been a key to provide a sustainable cocoa production. Earthworms, as decomposeragents in soil, may provide a sustainable way of improving soil fertility level. The objective of this study was to quantify top soil earthworm population andsome important soil characteristics, e.g. soil moisture, organic C, total N, and pH to see if there was any response observed due to different level and type oforganic waste applications. Their surface populations, i.e. at 5–10 cm depth, within cocoa circle were investigated with respect to different type of organic wasteapplications, i.e. cocoa pod waste, cocoa leaf waste, and sheep manure. For cocoa derived organic matter, the level of application was arranged at 5, 10, and 20 ton/ha to obtain an optimal condition at which the highest population of earthworm is obtained. A field investigation was performed at a square of 900 cm2 sizedarea, and extending down to 5–10 cm depth. Additionally, the effect of organic waste to top soil characteristics were also determined mainly to some importantparameters such as soil moisture, organic carbon, total nitrogen, and soil pH (H2O). Our analysis suggest that field heterogeneity condition may limit the conclusion, mainly related to the question of to what extent the effect of organic wastes to the changes in terms of soil characteristics. The application of organic wastes was able to increase the population of earthworms. Their highest abundance was obtained following the application of cocoa pod at 20 ton/ha, which was about 5 times higher than the population in the control.

Abstract

Jimma zone is one of the most potential coffee producing areas in Ethiopia. The livelihood of the farmers is mainly depend on coffee production. However,majority of them are smalholders characterized by traditional farm management system and limited use of coffee production technology. The aim of this study was to assess the adoption status of different coffee technologies in Jimma zone and to identify the determining factors of coffee technology adoption in the area. In the study, 393 respondents were involved and the adoption status of six selected coffee technologies, namely: the adoption of improved coffee variety, stumping, pruning, fertilizer, shade and mulching was investigated. Accordingly 67.4 % of the sample respondents did not use improved coffee variety. Similarly 45.8%, 31%, 53.4%, 4.1% and 25.7% of the farmers have not yet started to use stumping, pruning, fertilizer, shade tree and mulching, respectively. The factors influencing the adoption of each of these technologies were analyzed by using binomial regression model. As a result, age was found to be significant and negatively correlated with adoption of improved coffee variety. Sex of the farmer was the second variable which was found to be significant and had a negative correlation with mulching practice. Educational status was the other important factor which was found to be significant and had a positive correlation with adoption of the improved coffee variety, stumping technology and using shade tree. Family size was also found to be significant and had a positive correlation with using of stumping technologies, pruning, fertilizer application, mulching and shade trees. Dependency ratio, which was significant and showed a negative correlation with stumping and fertilizer application, was found to have a positive correlation with pruning. Likewise coffee farm size was found to be significant and had a negative correlation with improved coffee variety, fertilizer and mulching but it had a positive significant correlation with stumping. The coffee growing experience of the farmers was also significant and had a negative correlation with stumping, pruning and fertilizer. Moreover development agent support had a significant positive correlation with adoption of improved coffee variety, stumping, pruning, fertilizer application and mulching.Market distance was a factor that had a negative correlation with adoption of improved coffee variety, stumping, shade and mulching. Cooperative membership also showed a significant and negative corelation with improved coffee variety and pruning. Credit on the other hand was found to have a positive correlation with fertilizer application and was negatively correlated with the adoption of pruning practice and mulching. The total income of the household was found to be significant and had a positive correlation with adoption of improved coffee variety, pruning, using fertilizer and using of shade tree and training was also found to have a positive relationship with adoption of improved coffee variety, stumping technology, pruning practice, using shade tree and mulching.

Abstract

The continuous fall in the output of cocoa in Nigeria in the past years has been a great concern to the Nigerian Government. Cocoa which is the majorexport crop in Nigeria is experiencing drop in the foreign exchange earnings accruing to the Nigerian Government from its exportation. It is therefore necessary to restore the relevance of cocoa export to the forefront. This necessitated the Federal Government to embark on phase 1 of a programme called Good Agricultural Practices (GAP 1) in which selected cocoa farmers were trained on best sanitation practices that will improve cocoa production. This research determined the effects of farm sanitation training on cocoa output and also determined the relevance of farm sanitation training in cocoa production. Using random sampling procedure; one hundred and ten (110) respondents were selected from the 140 farmers trained on cocoa farm sanitation under the GAP 1 programme of Federal Ministry of Agriculture in partnership with Ondo State Agricultural Development Programme (ODSADP). A well-structured questionnaire was used to gather information from the farmers. Data were analysed using descriptive and inferential statistics such as Chi-square, Pearson Product Moment Correlation and paired T-test. The results revealed that majority (64.5%) of the farmers were male and married (67.3%). The average age of the respondents was 56 years, 18.2% had completed primary school education. The study revealed that cocoa farmers were trained on removal of black pods, cankers, mistletoes, chupons, termites and weeds. The findings also revealed that there was a significant relationship (x2 = 13.220, P = 0.040<0.05) between respondent’s marital status and level of use of farm sanitation training. There was also a significant difference between the cocoa farm output before and after farm sanitation training. There was an increase of cocoa output of the respondents by average of 41.28kg/ha. The use of farm sanitation training was responsible for 7% proportion of the increase in the output of the respondent’s farm. The results of the study further show that there was high level of contact betweenthe cocoa farmers in the study area and the extension agents. Major source of information to the respondents was extension agents of Ondo State ADP. Thefarmers practised the various farm sanitation techniques on which they were trained such as removal of canckers, removal of mistletoes, removal of chupons, hand weeding and picking of unwanted materials. The training variable with the highest impact on the output was removal of pods infected with black pod which brought about 0.290 units change in the output of the cocoa based on the coefficient.

Abstract

Litter plays a crucial role in the formation of soil organic carbon (SOC), and potentially affects different pools in the context of soil carbon cycle. To improve knowledge and understanding with respect to the dynamics of carbon in coffee and cocoa cropping systems, there is a need to develop a mechanistic model to explain the formation of carbon especially in different background of soil, climate and agronomic management. Short-term observation was performed in different cropping systems, i.e. coffee (Coff) and cocoa (CoL) with lamtoro(Leucaena sp.) shade trees, and cocoa with oil palm (Elaeis guineensis) shade trees (CoP), and teak (Tectona grandis) conservation area, to investigate the quantitative amount of leaf litter-derived carbon. Additionally, to improve the understanding with respect to the formation of soil organic carbon, a simple model is developed by employing organic carbon storage coefficient (hi) as parameter to validate the observation data from Coff and CoL plots. Leaf litter is collected daily with concomitant microclimate records, i.e. air temperature, relative humidity, light intensity, and soil temperature. Composite soil and leaf samples are collected for organic carbon, soil moisture content, and leaf relative water content (RWC), for laboratory identification. Analysis of data suggests the presence of cropping system effect, i.e. shading condition and agronomical practices such as pruning, to microclimate variations except for soil temperature. Furthermore, cropping systems do not significantly influence soil moisture content, amount of organic carbon, and RWC. With higher model efficiency (EF), the simulated model fits better for CoL, EF 0.95, than Coff, EF 0.58. Model simulation, with both hi values are 0.017 and 0.014 in Coff and CoL, reveals a possibly cropping system specific curve pattern. A faster SOC formation in Coff plot has suggested a crucial role the amount of leaf litter to support with continuous carbon supply. The simulation implies the presence of soil related-maximum point limiting carbon storage capacity

Abstract

Cocoa seeds are recalcitrant with some problems in their storage due to lack of dormancy period. This study aimed to find out the effect of cocoa pod storage in two different temperatures and the storage period towards seed viability and growth of the seedlings. This study applied a split-plot design with storage temperature as main plot and storage period as sub-plot. Cocoa pods of Sulawesi-1 clone were harvested and stored at 20ºC and 29ºC for 3, 7, 14, and 30 days. The stored cocoa seeds were then sown for three months. The findings showed that the storage of cocoa pods at 20ºC for 30 days causing the seed water content was 45%, the growth of the seedlings after the storage was 98.7%, and could press the pod shrinkage (1.6%). The storage of cocoa pods at 29ºC for 30 days could accelerate the reduction process by 68.2%, decreased germination of seeds upto 83.4%, and reduced the water content by 44.2%. The pod storage at 20ºC for 30 days showed a high value in some aspects such as seedling height, stem diameter, leaf area, seedling fresh weight, and shoot/root ratio. The storage of pods at 29ºC for 14 days indicated a high score in the character of germination, seedlingheight, stem diameter, and fresh weight of seedlings. The storage of pods at room temperature could be conducted for 14 days, meanwhile, at controlled temperature, it could be conducted for 30 days.

Abstract

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.

Abstract

Cocoa plant husks is one of the source of pectin. Pectin in the food industry is used as thickener, gel agent and stabilizer. The aim of this study was to determine the characteristics of the pectin from cocoa pod husks with variation in temperature and extraction times. In this study the extraction of pectin from cocoa pod husk was carried out with hydrochloric acid solvent, with 40, 60 and 80 minutes extraction times at 65oC, 80oC, and 95oC. The results showed that the extraction temperature (65oC, 80oC, and 95oC) and extraction time (40, 60, and 80 minutes) had no significant effect on metoxyl content, galacturonat acid, equivalent weight, and pectin content, but the extraction time had a significant effect on the acetyl number and the degree of esterification. The highest yield of pectin was obtained at extraction temperature of 80oC for 60 minutes. The pectin content in cocoa pod husk is larger than the content in banana skin. The characteristics of cocoa pod husk pectin powder are brown, with moisture content 10.56-11.96%, ash content 6.82-8.97%, methoxyl content 3.51-4.86%, galacturonic acid content 41.38-88.40%, esterification degree 10.76-19.96%, acetyl number 14.55-20.90%, equivalent numbers 663.83-1549.22, pectin content 9.52-19.51 and yield 5.55- 7.70%. IR Spectrum showed that there was no difference in the functional groups between standard, commercial, and pectin extracted at different temperatures.

Abstract

The intensity of vascular streak dieback (VSD) disease is one of the major causes of decreased fine flavor cocoa production in Indonesia; therefore, it is essentialto develop superior planting materials resistant to this disease. The purpose of the study was to conduct initial identification of yield potential and resistancelevel to VSD disease in several promising clones of fine flavor cocoa and to identify bean quality profile. This study was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember, Indonesia, with an altitude of 45 m above sea level (asl.) and C climate type, according to the Schmidt-Ferguson classification system. The study design used a complete randomized block design consisting of 13 promising clones and 3 superior clones of fine flavor cocoa as control. Each treatment was repeated 4 times in blocks, and each plot consisted of 5 plants. The results showed that PNT 16 was potential to be developed as a superior promising clone of fine flavor cocoa with high yield potential (66.6 pods/ tree/year equal to 2.52 kg dry bean/tree/year) and low VSD level (VSD score: 0.4) in first year of production (4 years old after planting). The superior promising clone of PNT 16 comprises of 35.1 beans per pod with good quality, weighed by 1.25 g/bean, and a higher percentage of white seeds above 80% (94.9%). Furthermore, the specifications of the main flavor attributes are similar to ICCRI 09 and dominated by the browned roasted, nutty and browned fruit aroma. Therefore, the clone has the potential to be developed as one of the special cocoa products.

Abstract

The availability of drought tolerant rootstock becomes one of solution to obtain tolerant cocoa clone at drought condition. The production of rootstock is easier and faster by using prope-legitimate seeds as plant materials. Seed germination selection phase can accelerate the obtainment of tolerant cocoa rootstocks. The tolerance trait of prope-legitimate seeds can be determined by seed germination on media induced by polyethylene glycol (PEG) solution. To determine the tolerant seeds, it is effective by using a specific character as selection criteria. This study aimed to obtain criteria and selection character to determine droughttolerant characteristic of prope-legitimate seed through PEG 6000 induction in the germination phase. The research was conducted at the Agronomy Laboratoryof the Indonesian Coffee and Cocoa Research Institute, Jember, East Java, Indonesia, used split plot design with five replications as experimental design. The main plot was solution of 0% and 6% PEG 6000, while the subplot were prope-legitimate seeds of 13 cocoa clones. The result showed that germination ability and sprout fresh weight were suitable as selection criteria to determine tolerant characteristic of prope-legitimate seeds to drought stress. Based on the value of tress susceptible index and clustering analysis, the tested prope-legitimate seeds were divided into three groups. The group of tolerant genotype consisted of Sca 06, while the group of medium tolerant were ICCRI 03, Sulawesi 02, KW 641, TSH 858, KEE 02, Sulawesi 03, and KW 617. The susceptible group consisted of six genotypes, namely ICS 60, KKM 22, KW 516, Sulawesi 01, and MCC 02.
