BRIEF HISTORY OF THE INSTITUTE:   The National Horticultural Research Institute (NIHORT), Ibadan started as the “The National Fruit and Vegetable Research and Development Centre (NFVRDC)” with the assistance of UNDP/FAO Project NIR/72/007 in 1975.  The Federal Government through Agricultural Research Institutes Establishment Decree Order No. 35 of June 1976, established the “National Horticultural Research Institute (NIHORT)” along with other Agricultural Research Institutes in the country.

The Institute’s headquarters is situated on a 310 ha of land at Jericho Reservation Area here in Idi-Ishin, Ibadan in the rain forest zone of South Western Nigeria.  The Institute also has five established outstations located at;

  1.  Mbato – Okigwe Imo State on an 810-hectare land in the humid zoneof South Eastern Nigeria.
  2.  Bagauda in Kano, Kano State on 110 hectares of land in the semi-arid zone of Northern Nigeria.
  3. Otukpa in Benue State in North Central zone of Nigeria with current land area of 15.6 hectares.
  4. Riyom near Jos, Plateau State.
  5. Dadinkowa, Gombe, Gombe State. 


To develop sustainable production and utilization of horticultural crops in order to achieve excellence in fruits, vegetables, spices, ornamentals as well as aromatic plant research in Nigeria. 


To develop horticultural produce and products for local and export markets with attendant health, industrial raw materials and employment generation benefits.


The institute has the mandate to conduct research into Genetic Improvement, Production technologies, Processing, Storage, Utilization and Marketing of Tropical Fruits, Vegetables, Ornamentals, Spices, other Medicinal and Aromatic plants of nutritional and economic importance.
