The aim of using this method was to find out superior varieties of Arabica coffee having appropriate specific traits and adaptable to such locations and accelerating the process of variety adoption by local farmers. Selection process was initiated by the farmer（s） based on high yielding performance by using their native experiences. The next step was conducted by plant breeder in collaboration with coffee farmers and other relevant scientists to evaluate more detail of cup quality, resistance to leaf rust and/or parasitic nematode as well as yielding potential and agronomic traits at different farmer＇s sites for several years observations. Research finding showed that three selected varieties namely Sigarar Utang, Gayo 1 and Gayo 2 had already been released by Minister of Agriculture for commercial planting at North Sumatera and Gayo highland. They performed excellent cup profile with high yielding ability （more than 1 t/ha） and tolerant to leaf rust disease. Therefore, it could support origin specialty coffee product at Gayo and Lintong highlands. However, observation over of selected local variety at Kendenan Plateau namely Salongge variety performed lower yielding ability （below 1 t/ha） and less stable yield over years as well as more heterogenous population in their offsprings than that of existing released varieties planted at the same location. Therefore, it could not be released as local varieties which adapted to specific location.展开更多

Its specialty is to innovate, through biological solutions with the vision of the future, once there is a strong demand of food and beverages free of chemical residues and with lower employing of these substances along the production chain by several consumers. The innovative products are generated from microorganisms tested regarding its capacity to promote yield protection, pests and disease control, acceleration of the desmucilage waste water treatment, and improvement of process of faster solubilization, that depends on natural phosphate fertilizers. The goal of this article is to approach the activities that have been developed in this start-up and the knowledge about biocontrol and natural antimicrobials produced by fungi resulting in innovative products to attend the world claim for products free of chemical residues of any kind and harmless to the consumers, environment and workers.展开更多
