Nigeria is the highest producer of yam in the whole world. Yam is a staple food crop for many Nigerians.

This agricultural review covers such areas as the meaning, importance and factors influencing extension technology adoption, importance of yam production in Nigeria, the yam minisett technology and its advantages over milking, the farmers traditional method of seed yam production.
