Trinidad and Tobago

The climate is maritime tropical with a dry season, which extends from late December to late May characterized by reduced frequency and intensity in rainfall. During the rainy season, which extends from June to early December rainfall is both higher in frequency and longer in duration than in the dry season. The remaining periods in late May and the rest of December are considered transitional.
The country, especially the maritime areas, are buffeted by east-north-easterly winds which have a marked effect on rainfall. The mountains run in the same direction as the prevailing winds and this results in a rain shadow effect. Generally rainfall is evenly distributed and is particularly heavy in the west (mean = 1870mm). There is a two-week dry period which interrupts the rainy season in September/October and is known as the petit careme.
Sea surface temperatures are stable and range between 26.5 °C and 28.0 °C in the wet and dry seasons respectively.

The Republic of Trinidad and Tobago comprises two separate islands which are located roughly between 10° and 11.5° N latitude and 60° and 62° W longitude and about 14 km off the eastern coast of Venezuela at the closest point.

Although historically the main horticultural crops are the commodity crops which were developed for export (cocoa and coffee, coconuts), other horticultural crops are citrus, floriculture (ginger lilies, orchids and anthuriums), fruits (mangoes, papaw, barbadine) and vegetables (peppers, tomatoes, melogene, ochroes, etc.). Arboriculture is predominantly on the slopes of the three mountain ranges in the north, central, and south.

Research Thrusts
The major research thrust are in the Ministry of Agriculture, Land, and Marine Resources, Research Division and the University of the West Indies, Faculty of Agriculture and Natural Sciences. Several state and regional institutions also conduct research in horticulture, e.g. Caroni (1975 ) Ltd.. Caribbean Research and Development Institute which is active in the agronomy of sugarcane and rice.
