The National Root Crops Research Institute, Umudike, in collaboration with the International Institute for Tropical Agriculture (IITA), Ibadan, has substantially contributed to the National Food Security and sufficiency through research and extension activities on root and tuber crops. The following achievements are outstanding:
- Nigeria is now ranked first in the world production of cassava, yam and cocoyam with total annual productions of 54, 32 and 4 million metric tonnes, respectively.
- Irish potato production in Nigeria has increased from 523,000 metric tonnes in 1975 to over 750,000 metric tonnes in 2006. Production has also expanded from Jos Plateau to Sokoto, Kaduna, Kebbi, Kano Jigawa, Bauchi, Yobe and Borno States where potato is produced under irrigation during the harmattan months (November to February). Also, the Institute has developed technique for the use of true potato seed (botanical seed) instead of the traditional seed tubers for seed potato production. The technique has the potential to reduce potato production and storage costs by over 35% and double the present seed supply to farmers.
