stock 3,5.9 3,4.3 4,1.5 Source : From Ref. 3. Coffee Processing 6 In more recent times, hybrid between . arabica

andC. robusta was developed in Ivory Coast, namely, . arabusta , which is reported to have better avor quality than

. robusta and more disease resistance than . arabica . The beans also have lower caffeine content. Cultivation of this species is currently restricted to limited areas because of pooryield and diminished size. Attempts have been made to develop coffee that is free of or has lower level of caffeine but with little success. 2 BOTANY The coffee plant is small tree, which in the case of . arabica is maintained at 5 ft (1 cm) and in the case of . robusta at 5.5 to 6.0 ft (1 to 1 cm). This can grow up to 2 ft (7.6 ) in the wild state but is pruned for two reasons: () to facilitate harvesting and () to maintain optimal tree shape. The primary branches are opposed and horizontallydrooping, and the leaves grow in pairs on short stalks. They are about 1 cm in Coffea arabica and longer in Coffea canephora , oval, and fairly dark green in color (. Various methods of propagation may be used, including cuttings, grafting, and lay- ering. The use of cuttings is the normal commercial practice. The coffee plants yield within 3 years and last up to 3 years. An altitude of 2 ft (6 ) is ideal for coffee, but it can also be grown at up to 6 ft (1 ). As in the case of tea, thehigher the altitude, the better the quality. But the limiting factor is that coffee cannotwithstand frost. The ideal climatic condition for coffee is 7 C8C and rainfall 6 in (1 cm). The yield of coffee is totally dependent on the owers produced by the plants and, more importantly, on the percentage of fruit set from the owers. The bl
