The institute conducts research into genetic improvement of economically important root and tuber crops such as cassava, yam, cocoyam, sweet potato, Irish potato, ginger, rizga, Hausa potato, sugar beets and Turmeric. It also researches subjects such as crop cultivation techniques, storage, processing and utilization of the crops, concentrating ...
According to a 2012 study, an estimated 300,000 households in Nigeria engage in potato production, which translates to an average planted area of 1 hectare (2.5 acres) per household each year. [12] The country's main potato-planting region is the Plateau State (Barkin Ladi, Bokkos, and Mangu) which accounts for almost half of the national ...
World yam production Yam in a market. Nigeria is by far the world’s largest producer of yams, accounting for over 70–76 percent of the world production.According to the Food and Agriculture Organization report, in 1985, Nigeria produced 18.3 million tonnes of yam from 1.5 million hectares, representing 73.8 percent of total yam production in Africa.

Sweet potato sprouting "slips" Sweet potato harvest in Nash County, North Carolina, United States Depending on the cultivar and conditions, tuberous roots mature in two to nine months. With care, early-maturing cultivars can be grown as an annual summer crop in warm temperate areas, such as the Eastern United States and China.
With plentiful water supply, the reservoir remains full throughout the year. [1] The reservoir provides raw water to the Asejire and Osegere water treatment plants in Ibadan . [ 2 ] The water supply project was completed in 1972, and has a capacity of about 80 million liters per day, of which 80% is used for domestic purposes.
The sweet potato (Ipomoea batatas) is a very important crop for subsistence farmers in Africa and developing countries in other regions. [1] [2] Its relatively short growing period, tolerance to drought and high yield from poor soils lead to its use as a famine reserve for many of these households.
Aerial or potato yams (D. bulbifera) have antinutritional factors. In Asia, detoxification methods, involving water extraction, fermentation, and roasting of the grated tuber, are used for bitter cultivars of this yam. The bitter compounds in yams also known locally as air potato include diosbulbin and possibly saponins, such as diosgenin. [31]
The study also showed that peeling removed 91–98% and washing 33–47%. Residues of chlorpropham were detected in the boiled potatoes, in the boiling water, in the French-fried potatoes and in the frying oil. According to this study, the theoretical dose for a 20 kg infant eating 100g of crude-peeled tuber would be 0.00018 to 0.00342 mg/kg.
