Coffee Breeding in Kenya: Achievements, Challenges and Current Focus
(2015)Coffee production in Kenya is seriously constrained by two fungal diseases namely Coffee Berry Disease (CBD) caused by Colletotrichum kahawae (Waller & Bridge) and Coffee Leaf Rust (CLR) caused by Hemileia vastatrix (Berk. ... -
Coffee Drying in a Rotary Conduction-Type Heating Unit
(Blackwell Publishing Ltd, 2004-06-01)Parchment coffee (Arabica) was dried from an initial moisture content of about 90% to 10% dry basis (db) in a recirculating rotary conduction type heating unit at controlled plenum temperatures of 100, 120 and 140C or ... -
Coffee Sustainability in Kenya: Role Played by Improved Varieties
(2015)Coffee production in Kenya has been sinking since 1980s. The condition has been worsened by climate change phenomenon which has brought new production challenges in recent years. The biggest challenge is the changing ... -
Combining Ability of Inbred Lines of Maize (Zea mays) in Kiambu and Embu Counties, Kenya
(Science Domain International, 2016-08)Despite the fact that virtually all households in Kenya grow maize, over 60% of them are net maize buyers because they do not produce enough for their consumption. This is due to both biotic and abiotic factors such as ... -
