Over a 10-year period (1984-1994), observations were made on the phenological changes occurring in fruit trees/crops. In an orchard at Codrington Agricultural Station, internationally important cultivars of mango (Mangifera indica), citrus (Citrus spp.), avocado (Persea americana) and carambola (Averrhoa carambola) were monitored. Other species were observed at various locations. Information on flowering and fruit production trends is presented. The period of February to April was a strong flowering peak for species that exhibit synchronous rhythmic bearing habits, although a weaker peak often occurred in the October to November period. July to October was a strong peak, period for fruit maturation when all species were taken into account. A particular group of species had fruiting peaks only in the May to July period. Some species had two fruiting peaks; one occurring around May to July and a second around October to January. The observed variations in annual growth and production rhythms among and within species seem to be sufficiently distinct as to require different management strategies (including spatial arrangement). The phenological patterns of the species/cultivars are discussed in relation to orchard management approaches in the Barbados environment.
