Other variables, namely fertilization frequency, fertilization method, fertilization time, shape trimming, production prunin...
Evaluation of arabica coffee propagation using cell suspension culture
IOP Conference Series: Earth and Environmental Science, 2020
Arabica coffee is highly produced in Indonesia, thus need to be propagated using a powerful approach like cell culture in somatic embryogeneis for providing seedlings. The study aimed to evaluate the use of cell cultures in somatic embryogenesis on several Arabica coffee genotypes. The embryogenic calli (200 mg) were subcultured into solid and liquid regeneration media (half concentration of Murashige and Skoog [MS] added with 2 mg/L of kinetine, 35 g/L of sucrose, 400 mg/L of casein hydrolisate, and mall extract). For the somatic embryos germination,MS media was used by adding it with 0.3 mg/L of BAP and 40 g/L of sucrose. The solid media was added with 2.5 g/L of phytagel. This study was used Factorial Completely Randomized Design (CRD) (genotype and media solidity) with 10 replications.. The results showed that production of the number of somatic embryos is highly depended on the genotypes. The size of somatic embryos, fresh weight, and root length on the torpedo and germination phases in liquid media was higher than solid media. Using liquid media at germination phase isn't recommended, because it can resulted hyperhydricity.

The Batabual Arabica coffee variety in Buru Regency, Maluku Province, has the potential to be developed as specialty coffee. However, the planting conditions are generally poorly maintained, most of the plants are old, the plant population is declining, and productivity is low (200-350 kg/ha/year). For this reason, government intervention is needed for the rehabilitation and development of Batabual coffee. This study aims to analyze the financial feasibility of Batabual coffee farming and design a development model for Batabual coffee. This study uses analysis of B/C ratio and NPV, as well as FGD to develop steps for developing Batabual Arabica coffee. The results of the financial analysis showed that Batabual Arabica coffee farming was feasible with a B/C ratio of 1.13 and an NPV of IDR 45,284,774. The three main things needed in the development of Batabual Arabica coffee are the establishment of seed plantations as a source of Batabual coffee seeds, improvement of cultivation techniques, and the establishment of farmers' economic institutions to strengthen the bargaining position of farmers, improve the quality of coffee products and expand the market.
Review of Arabica Coffee Nursery Management Research in Ethiopia
Journal of Biology, Agriculture and Healthcare, 2015
Forest soil or a mixture of top soils (TS), compost and sand (S) in 3 : 1: 0 and 2 : 1 : 1 ratios or blends of organic manure and TS in 1 : 4, 2 : 4 and 3 : 4 ratios resulted vigorous seedling growth. Applying 750 mg P or a combination of 2.31 g lime and 250 mg P pot-1 (2.5 kg sieved TS) ensured production of quality seedlings. Sowing coffee seeds at a depth of 1 cm with the grooved side placed down and embryo tip up had improved germination. Seedbeds covered with 3-5 cm thick mulch after seed sowing and watered at 2 days interval until hypocotyl emergence had higher germination percentage. After emergence, with the removal of mulch, nursery beds provided with 50% over head shade and irrigated twice a week until seedlings attained 2 to 4 pairs of leaves and then after at a week interval produced vigorous seedlings. Sowing clean coffee seeds after soaking in cold water for 24 hours hastened germination and seedling growth. Soft wood single node cuttings with one pair of leaves and blends of TS, S, and manure in 2 : 2 : 1 ratio was recommended for vegetative propagation of hybrid coffee.
Sustainability for Growth and Productivity of Arabica Coffee in Lowland Regions of Bengkulu Province
International Journal on Advanced Science, Engineering and Information Technology, 2015
Arabica coffee usually grows well at the latitude of more than 700 m above sea level, but in Bengkulu Province, Indonesia the highland regions are mainly located in the conserved areas and prohibited for agricultural cultivation. These subsequent studies aimed to result in the most adaptive genotype of arabica coffee to the lowland environtment and the best planting gap of shading trees for improved coffee productivity. Two types of technology included in these studies were grafting of arabica and robusta as entress and understump, respectively, and enviromental engineering at a lowland area by planting shading trees at different distances. Four arabica entresses of S-1934, Kartika, Sigararutang and Andung Sari varieties were grafted with robusta understumps to produce so called four "robbika" genotypes. The robbika stumps were grown in the lowland region under shading trees of legume species which were pre-planted with varous planting distances. Results showed that four genotypes of robbika coffee grew better in the lowland region compared to all genotypes of arabica coffee as shown by parameters of growth, physiological characters and yield potential. Environmental engineering treatments showed that the 2.5 x 2.0 m planting distance resulted in the best soil and microclimate conditions in the robbika plantation areas.

Coffee seeds with moisture content grater than 40% when stored in moisture vapor barrier containers, viz. glass jar and polythene bag had retained their viability and vigor for a longer period. However, sowing coffee seeds immediately after harvesting and processing was found to be the best option for higher germination rate and better seedling growth. Pre-germination is the primary cause of multiple and crooked tap roots and eventual tree death in the field. Forest soil or a mixture of top soils (TS), compost and sand (S) in 3 : 1: 0 and 2 : 1 : 1 ratios or blends of organic manure and TS in 1 : 4, 2 : 4 and 3 : 4 ratios resulted vigorous seedling growth. Applying 750 mg P or a combination of 2.31 g lime and 250 mg P pot -1 (2.5 kg sieved TS) ensured production of quality seedlings. Sowing coffee seeds at a depth of 1 cm with the grooved side placed down and embryo tip up had improved germination.

There is a tendency for an increase in the number of damaged beans in certain areas producing Arabica coffee, which is thought to be related to the coffee farm elevation. The aim of this research is to examine the interactive effect between farm altitude and variety on coffee yield and quality. Factors investigated were farm altitude which consisted of 3 categories, namely low (>1,000-1,200 m asl), medium (>1,200-1400 m asl), high (>1,400-1600 m asl), and coffee varieties namely Timtim, Borbor and Ateng Super. The results show that the highest coffee bean yield is obtained from medium farm altitudes (>1200-1400 m asl), while the lowest yield is obtained from low farm altitudes (>1000-1200 m asl). Interaction between the two factors reveals that all three varities perform very well in medium altitude farm, while in low altitude, the Borbor shows a better adaptation and is more resistant to CBB attacks. In high altitude area, the Ateng Super adapts better to a lower environmental temperature. The percentage of defective beans decreases with an increase in farm elevation. The lowest average defective bean (8.3%) was found in high altitude, while the highest average defective bean (14.3%) was found in low farm altitude.
