Pelita Perkebunan, Coffee and Cocoa Research Journal (CCRJ): ISSN:0215-0212 Since its establishment in 1911, Indonesian Coffee and Cocoa Research Institute (ICCRI) formerly Besoekisch Proefstation, had published its research findings through a journal call Mededelingen van het Besoekisch Proefstation. Between 1948-1981 the research institute was under the supervision of Bogor Research Institute for Estate Crops, and published its research findings through De Bergcultures which was later changed to Menara Perkebunan. Since the institute held the national mandate for coffee and cocoa commodities, and due to rapid increase in the research findings, ICCRI published its first issue of Pelita Perkebunanjournal in April 1985. Pelita Perkebunanis an international journal providing rapid publication of peer-reviewed articles concerned with coffee and cocoa commodities based on the aspects of agronomy, plant breeding, soil science, crop protection, postharvest technology and social economy. Papers dealing with result of original research on the above aspects are welcome, with no page charge. Pelita Perkebunan is managed by Indonesian Coffee and Cocoa Research Institute (ICCRI), which publish the research findings not only for coffee and cocoa but also other commodities relevant with coffee and cocoa, i.e. shade trees, intercrops and wind breakers.

Abstract

El Nino effect as impact from global climate change needed anticipation effectively to keep cocoa production still give farmer benefit because effect of long dry season make some trouble in cocoa production. Cocoa production technology package that suitable in dry land needed for sustainable and empowerment cocoa production in marginal dry land. Principal component of this technology package is superior planting material because success of cocoa production depend on accuracy of selecting planting material. Indonesian Coffee and Cocoa Research Institute consistently carries out cocoa breeding programs aimed at overcoming problems in the field, specifically to obtain superior planting material that is tolerant to biotic and abiotic stress. This research method was carried out by observing 22 promising clones of cocoa that were planted in the Kaliwining experimental station in the 2013-2017 observation period, each clone planted in three blocks. The observed variables included estimation of production, resistance to VSD, helopeltis, and pod rot. Based on multivariate analysis, it was found that ICCRI 09 had a stable production performance from 2013 - 2017 while the promising clone of KW 641 had a special adaptation to dry conditions. Both of these clones have the potential to be developed as drought tolerant planting material to overcome the impact of climate change on cocoa production. The observation results of pest and disease attacks obtained a pattern that the clones that have tolerance to drought have good resistance to VSD.

Abstract

The income of smallholder coffee farmers can be increased by optimizing the added value of the product through increased entrepreneurial capacity. Coffee farmers need to adopt innovations and new approaches that are more sustainable with organic farming systems. The purposes of this study are; (1) identifying differences in characteristics, support of government extension services, private extension agents, and environmental support for smallholder coffee farmers and (2) analyzing the effect of characteristics, government extension services, private extension agents, and environmental support on the entrepreneurial capacity of smallholder coffee farmers. This study was carried out at Arabica Coffee Center in Bondowoso Regency and Robusta Coffee Center in Malang Regency, East Java from August to October 2019. Data were collected through interviews with questionnaires in a total of 376 smallholder coffee farmers. Data were analyzed using descriptive (SPSS) and inferential statistics (structural equation model/SEM analysis using Smart PLS). The results of research showed that non formal education and roles of private extension agents were found to be low. Moreover, motivation, government extension support, environmental support, and entrepreneurial capacity of smallholder coffee farmers were categorized as moderate. Factors significantly influenced entrepreneurial capacity of coffee farmers included: characteristics of farmers, government extension support, roles of private extension agents, and environmental support. The role of government to strengthen private extension agents is possible through partnership between coffee farmers, government and exporter or private sectors.

Abstract

Arabica coffee (Coffea arabica) cultivation in the medium altitude (700-900 m above sea level, asl.) will face problems such as decreasing productivity, physical, biochemical and cup quality and increasing intensity of pest and diseaseattacks. Utilization of plant material that has good productivity and cup quality, resistance to pests and diseases is an effort that can be done to overcome theseproblems. The aims of this study is to evaluate performance of Arabica coffee quality grown at high and medium altitude area, as well as biochemical compound and cup quality changes that occur due to influence of genotypes and genotype × altitude interactions. Eight genotypes of Arabica coffee were evaluated at two locations namely KP Andungsari (1,250 m asl.) and Kalibendo (700 m asl.). The field design for each location was randomized complete block design with three replicates. Observations were made on the two quality aspects, namely the biochemical compounds and cup qualities. The result on the biochemical compounds showed that the altitude significantly affect to the content of caffeine, sucrose, and trigonelline. Effect of genotype × altitude occured to the caffeine, trigonelline, and sucrose content. Diversity of chlorogenic acid content was caused by the genotype effect. Cup test results showed that genotypes grown at high altitude had a better cup quality than genotypes on medium altitude. Cup quality variables that were changed due to altitude difference were fragrance and aroma, flavor, aftertaste, acidity, balance, and overall, while the cup quality variable that did not changed was the body. Characters of coffee aroma at the high altitude were floral, spicy and fruity, while at the medium altitude were herbal, green and grassy. The best quality genotype at the high altitude was K8, while at the medium altitude was K29. Environment (altitude) gives greater influence to the formation of coffee flavor variations produced compared to genotypes.

Abstract

Sulawesi exhibits unique land characteristics as a result of complex geological and geomorphological processes. The information related to what extent of theseprocesses affect regional soil characteristics is still limited. An investigation was performed on cocoa farms from three major cocoa producers, i.e. South Sulawesi, Central Sulawesi, and Southeast Sulawesi. A research was done to point out the key variables contributing to cocoa soil characteristics. Soil survey was performed based on available local information to collect top soil composite samples, i.e. 0–30 cm depth, in the circle of cocoa stand within 50–75 cm radius. A routine soil analysis was done to evaluate soil texture, organic carbon (C), total nitrogen, K, Ca, Mg, soil pH (H2O), and some micronutrients, i.e. Fe, Cu, and Zn. To simplify the complexity, the multivariate data was submitted into principal component analysis (PCA). Additional mapping of soil variable gradient through inverse distance weighting (IDW) interpolation was included in the analysis to improve our interpretations. Data show that the variability for almost all investigated variables is high with coefficient of variation (CV) of up to about 118% for Fe. While low variability with CV about 10% was observed for soil pH (H2O). The PCA demonstrates that the first five principal components (PCs) account for 56.89% of variance in the original variables. Two factors to be considered to explain the variation in the PCs was soil texture and parent material. Further analyses exhibit an association of sand, silt, and clay fractions to Southeast, Central, and South Sulawesi. Mineral compositions, such as K, Ca, Mg, Fe, and Zn, exhibit an important contribution to the parent material factor as they define the variability in the PCs. Additionally, the analysis of gradient maps may indicate the two physical environmental conditions, i.e. landform and geological setting, contribute to the specific characteristics of cocoa soil.

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

Cocoa is an important crop to the economies of countries such as Nigeria, Cote D’Ivoire, Ghana and Cameroon in West Africa. In an effort to revive cocoasector and increase cocoa production in Nigeria led to cocoa rehabilitation programme (CRPs) by the Federal Government of Nigeria. This study ascertainedthe adoption levels of farmers in cocoa rehabilitation programmes in South-west Nigeria. Data for the study were collected from 240 cocoa farmers through theuse of interview schedule and focus group discussion. Multistage sampling procedure was used in selecting respondents. Data were analysed using percentageand mean statistics. Results revealed that, adoption level was low for coppicing techniques (38.0%, 32.0% and 33.0%) and complete replanting (25.0%, 27.0% and26.0%) of cocoa rehabilitation programme, respectively, for the three groups of farmers (farmers that benefitted from government agency cocoa resuscitationprogramme, farmers that benefitted from non-governmental agency cocoa resuscitation programme and farmers that benefitted from both governmental and nongovernmental agencies). Planting of young cocoa seedling under old cocoa trees (98%, 94%, 95%) and selective planting/gapping up (68.0%, 81.0% and 79.0%) had a very high adoption level for the three groups of the farmers. The most helpful agency in the adoption of cocoa resuscitation programmes was Agricultural Development Programme. To improve the level of adoption of cocoa resuscitation programmes, the federal government of Nigeria should further intensifyefforts in encouraging more farmers in cocoa rehabilitation programme by providing the necessary incentives (like distribution of free cocoa seedlings) to the farmers as at when necessary.
