Annual crops play an important role in the food security of the nation. The activities of this coordination help to ensure the improvement and development of annual crops across all the five agro-ecological zones of the country. They are developed and coordinated through four (04) research programs. Principal research activities include: germplasm collection and maintenance; varietal development; soil fertility enhancement and pests/diseases management.


  • Develop productive climate smart varieties that meet market needs;

  • Ensure the protection of crops against pests and diseases;

  • Develop appropriate agronomic practices;

  • Develop soil fertility enhancement techniques.

Research Programs

Cereals (Maize, rice, wheat, sorghum and millet)

This program develops high yielding, nutrient-rich varieties that are tolerant/resistant to biotic and abiotic stresses. Research also involves development of crop production and protection techniques.

Roots &Tubers and banana/plantain (Cassava, cocoyam, sweet potato, taro, potato, yam, etc.)

Research under this program lays emphasis on the development of high yielding adapted varieties, technical itineraries and production of quality planting materials.

Legumes and vegetable crops (Groundnut, cowpea, common beans, soybeans, okra...)

This program carries out research activities geared at developing highly productive legumes and vegetable varieties, rich in micro-nutrients and tolerant/resistant to biotic and abiotic stresses.

Industrial annual crops (Cotton, Sugarcane and Tobacco).

The research activities in this program focus on improving the production of cotton and sugarcane by developing varieties that meet the requirements of the fiber and sugar industries. Pests and diseases management is also an important activity of this program.

Salient results

  • Germplasms of various annual crops have been enriched with accessions collected locally and internationally.
  • Several high yielding varieties that are tolerant/resistant to biotic and abiotic stresses have been developed:
  • Maize: 13 varieties (4 to 10 t/ha)

  • Sorghum: 4 varieties (2 – 5 t/ ha).

  • Rice: Several varieties (5 to 9 t/ha).

  • Cowpea: 4 varieties (1 to 2 t/ha).

  • Common bean: 13 varieties (1 to 1.5t/ha)

  • Cassava: Several varieties (30 to 40 t/ha).

On-going projects


  • Development of more climate smart varieties;

  • Development of strategies to control emerging pests and diseases;

  • Capacity building of junior scientists and rural development stakeholders.
