Abstract
Though tea production continues throughout the year in Kenya, there ere monthly variations in yields and chemical composition attributable to the changes in environmental conditions. Total volatile flavour compounds (VFC), group I VFC, group II VFC and caffeine ere higher throughout the experimental period in black teas manufactured from plants here fertilisers ere applied than here fertiliser as not applied. Levels of thearubigins (TR) and flavour index (FI) ere generally high hen there as no fertiliser application. Theaflavins (TF) levels varied ith the time of the year but there as no clear trend due to fertiliser.Keywords
