<em>Temanggung is one of the centers of Robusta coffee production in Central Java, with a variety of potential local coffee clones. The exploration found that several numbers of local Robusta coffee clones had the potential to have high productivity and were resistant to pests/diseases. However, their level of genetic similarity to the superior clones that have been released has not been clearly identified. This study aimed to investigate the genetic variability of Temanggung local Robusta coffee clones based on SSR markers. The study was conducted at the Molecular Laboratory of the Integrated Laboratory, Indonesian Industrial and Beverage Crops Research Institute from February to December 2018. A total of 29 local coffee clones derived from Temanggung along with two control coffee clones (BP 42 and BP 358) were used. All the 14 SSR markers used in the present study were polymorphic and could cluster those local coffee clones into 5 major groups at a genetic similarity coefficient of 0.57. Four local coffee clones (Putih Daun Lebar, Lokal, Tugusari Hijau and Tugusari Kuning) were in the same group with control clones in group I. One local clone (Tugusari Hijau) had a genetic similarity with the control clone BP 358 at 0.91. Meanwhile, the other 25 local clones were in different groups from the control clones. These local clones, which showed genetic distance far from the control clones, can be selected as candidates for local superior clones in coffee breeding program.</em>

New Crop

Robusta coffee (C. canephora) covers 36% of world coffee production and has strategic relevance as a beverage that it is produced by thousands of small-scale producers around the world. Although mainly grown in Africa and Asia as opposed to Latin America, this situation is changing. Colombia is recognized as a producer of high-quality Arabica (C. arabica L.) coffee, however we argue that Robusta represents a great economic opportunity for small scale producers, for the industrialization of new products and for emerging coffee chains. Therefore, the objective of this review is to outline the agronomic value of Robusta coffee as a “new crop” in Colombia. As background we compare the better-known Arabica to the Robusta coffees from a Latin American perspective. Robusta shows differences in geographical distribution, genetics, originating species, physiology and phenology. Robusta and Arabica also differ in their chemistry, sensory attributes, industrial use, segments of market and price. Despite the marked differences between the two coffees, the popularity and consumption of Robusta has been on the increase due to the expansion of markets in emerging economies and in developed markers for home espresso preparation where it is used in high quality coffee blends. Robusta is currently replacing areas of other coffees due to hotter temperatures to which it is adapted. Although Robusta is still new to Colombia, this species has potential adaptation in lowland areas considered “non-traditional” for Colombian coffee cultivation and as a valuable component of agro-ecological production systems. Robusta is a novel crop option for certain regions that is needed for the future of coffee in Latin America and for growth of coffee production and consumption in Colombia.

Cordia Africana

In a first step to understand the interactions between Colfea arabica L. trees and mycorrhizae in Ethiopia, an investigation of the current mycorrhizal colonization status of roots was undertaken. We sampled 14 shade tree species occurring in coffee populations in Bonga forest, Ethiopia. Milletia ferruginea, Schefflera abyssinica, Croton macrostachyus, Ficus vasta, F. sur, Albizia gummifera, Olea capensis, Cordia africana, Ehretia abyssinica, Pouteria adolfi-friederici, Pavetta oliveriana, Prunus africana, Phoenix reclinata and Polyscias fulva. Coffee trees sampled under each shade tree were all shown to be colonized by arbuscular mycorrhizal fungi (AM fungi). Four genera and 9 different species of AM fungi were found in the soils. Glomus (Sp1, Sp2, & Sp3 & Sp4), Scutellospora (Sp1 & Sp2) and Gigaspora (Sp1 & Sp2) were found under all 14 shade tree species, whereas Acaulospora (Sp1) occurred only in slightly acidic soils, within a pH range of 4.93-5.75. Generally, roots of the coffee trees were colonized by arbuscules to a greater degree than those of their shade trees, the arbuscular colonization percentage (AC%) of the former being higher than the latter (significant difference at 0.05 level). Though differences were not statistically significant, the overall hyphal colonization percentage (HC%) and mycorrhizal hyphal colonization percentage (MHC%) were shown to be slightly higher under coffee trees than under their shade trees. However, the differences were statistically significant at 0.05 level in the case of HC% values of coffee trees under Pouteria adolf-friederici and MHC% under Cordia africana. Spore density and all types of proportional root colonization parameters (HC%, MHC%, AC% and vesicular colonization percentage, VC%) for both coffee and shade trees were negatively and significantly correlated with organic soil carbon, total N, available P, EC and Zn. Correlation between arbuscular colonization for coffee (AC%) and organic carbon was not significantly positive at a 0.05 level. Incidence of specific spore morphotypes was also correlated with physical and chemical soil properties. Results indicate that AM fungi could potentially be important in aforestation and help to promote coffee production activities in Ethiopia providing an alternative to expensive chemical fertilizer use, and would offer management methods that take advantage of natural systems dynamics that could potentially preserve and enhance coffee production.

Annual Survey

Assessing and prescribing fertilizer use is critical to profitable and sustainable coffee production, and this is becoming a priority concern for the Robusta coffee industry. In this study, annual survey data of 798 farms across selected Robusta coffee-producing provinces in Vietnam and Indonesia between 2008 and 2017 were used to comparatively assess the fertilizer management strategies in these countries. Specifically, we aimed to characterize fertilizer use patterns in the key coffee-growing provinces and discuss the potential for improving nutrient management practices. Four types of chemical (NPK, super phosphate, potassium chloride and urea) and two of natural (compost and lime) fertilizers were routinely used in Vietnam. In Indonesia, NPK and urea were supplemented only with compost. Farmers in Vietnam applied unbalanced quantities of chemical fertilizers (i.e., higher rates than recommended) and at a constant rate between years whereas Indonesian farmers applied well below the recommended rates because of poor accessibility and financial support. The overuse of chemical fertilizers in Vietnam threatens the sustainability of Robusta coffee farming. Nevertheless, there is a potential for improvement in both countries in terms of nutrient management and sustainability of Robusta coffee production by adopting the best local fertilizer management practices.

One of the causal factors affect coffee production declining in Indonesia is the decline in harvest area of coffee plants. The decline in the area of coffee farming is caused by the shift of farmers from coffee to other commodities, such as corn, vegetables and fruit. The research was conducted to determine new strategic steps in order to enhance robusta coffee production. To achieve the research objectives, Interpretative Structural Modeling (ISM) analysis and modeling techniques are carried out. This modeling technique does not require a large sample, so the sample used in this study is limited to 22 people from several related agencies. Data processing in research is carried out according to the needs of Interpretative Structural Modeling (ISM) analysis. The results show that the new strategy in developing Robusta coffee production is (1) rehabilitation of coffee plants, (2) rejuvenation of coffee plants, (3) selection of superior coffee varieties, (4) provision of farming roads, (5) coffee price stabilization, (6) intensification of coffee plants, (7) pest control, and (8) increased knowledge of farmers. These new combinations strategy can be strongly expected to enhance robusta coffee production in the country.

Monoculture farming of arabica coffee plantation does not support environmental sustainability. International market demands arabica coffee product in compliance with an environmentally friendly standard which promotes ecological-based management. This study aims to identify the ecological aspects of specialty arabica coffee cultivation, and to analyze the effect of shade tree population, the use of organic fertilizer, the pruning of coffee crop, land conservation, and the control of coffee berry borer on specialty arabica coffee production. The data of ecological aspect was collected from three regencies in North Sumatera Province, namely Simalungun, North Tapanuli, and Dairi. Production determinant was analyzed concerning farming cultivation in three districts of Simalungun Regency namely Sidamanik, Pamatang Sidamanik, and Dolok Pardamean. The location was determined with multi-stage cluster sampling and the farmer samples with simple random sampling. The ecological aspect was analyzed descriptively while the determinant of arabica coffee production was analyzed with multiple regression method. The result shows that the shaded arabica coffee farming covers only 32% of the total arabica coffee production in the study area with a population of 54 trees/ha. Land conservation conducted by the farmers utilizes coffee fruit mulch (92%), individual terrace (3%), rorak (4%), and bench terrace (1%). The arabica coffee farming system managed by the farmers consists of monoculture (30%), mix farming (24%), shade coffee (32%), and multistrata coffee (14%). The pruning of coffee plants and integrated control of coffee berry borer has a significant effect on specialty arabica coffee production. Land conservation, population of shade tree, and organic fertilizer are an important production determinant on arabica coffee production in the short-term. These three ecological variables play a role to maintain land preservation and support sustainable arabica coffee production in the long-term.
