The prevailing wind is from the north during the period December to March and brings dry air from the desert. During April to June the convergence zone is over Uganda due to south easterlies coming from Indian Ocean to meet the north easterlies. July to September there is divergence over the country due to the formerly south easterlies veering into the northern Indian Ocean as south westerlies, this is generally a dry period. The yearly average number of days with rain is 135 days and with snow it is 0. Uganda has a tropical humid climate, which is well suited for horticulture for the whole year.

Most of Uganda forms part of an interior high plateau which is lower in north and south of Africa than it is in Uganda. Uganda plateau surface major landscape is lower in the north and higher in the south and southwest. To the West is Mt. Rwenzori at 4800 m ,Mt. Elgon in the East at 4200 m and Rock mountains of Tororo while in the northeast are the plateau and mountains in Karamoja. Uganda which is 235,690 km2 has 3666,260 km2 of open water and 5,180 km2 of swamp. The dry land is underlain mostly by the World's oldest rocks estimated at 3 million years old which has been modified or altered by volcanic movements. In west and central soils are mostly reddish-brown loams about 25 cm deep. In the north and east the soils are light and black and rather shallow while it is sandy in the northeast. Volcanic soils appear in the southwest.

Some aspects of Horticulture can be found in Uganda including Floriculture under open land and in green houses, pomology, fruit and vegetables growing under open cultivation, essential oil crops cultivation and mushroom growing at household level.

Distribution of Horticulture
Horticulture is concentrated in three districts that are in the central region, near the Entebbe International Airport. Theses are Kampala, Mukono and Mpigi (See Local Geographical data and Climate for Central Region).

Research Thrusts
National Agricultural Research Organisation (NARO), Ministry of Agriculture Animal Industry and Fisheries (MAAIF) and University at Makerere University Agricultural Research Institute Kabanyolo (MUARIK). There are a few private farmers involved in floriculture and essential oils.

Nature of Institutes
Horticulture research is mainly directed to sustainable and cost effective growing systems, and is primarily conducted by two organisational institutions:
1. National Agricultural Research Organisation (NARO) a para-statal
organisation houses most of the Uganda Research Institutes including KARI
with horticulture activities.
2. Makerere University Agricultural Research Institute Kabanyolo (MUARIK).
