The Best Crops for Biofuel Production. Different crops are used for biofuel, including wheat, sunflower, soybean, and sugarcane. Biofuel production relies on energy crops grown in Europe, the U.S. and other places around the world. Alternative fuels are used to power vehicles and reduce greenhouse gas emissions.
Although yam production in Africa is 40% that. of cassava, the value of yam production exceeds all other African staple crops and is equivalent to the. combined value for the top three cereal crops â maize, rice and sorghum (Africa Yam Project, 2016). Yam is the preferred staple food in West Africa but demand is constrained by inadequate production and. losses in storage. The most important biotic constraints are nematodes, viruses and anthracnose.
