It is important to consider ways of boosting sweet potato production, taking full advantage of the fact that, it is a food security crop that surpasses other root and tuber crops in terms of agronomic potentials. Contributions of crop variety and plant spacing for maximum yields are apparently random. The book gives precise information to addressing low yields via a 3-year field experiment in 2007-2009 wet seasons at the Teaching and Research Farm of Abubakar Tafawa Balewa University, Bauchi, Nigeria using a 2x3x4-factor combinations to develop an appropriate technologies for increase quality crop yields and consequently encourage farmers to sustain and expand their farming units for better and attractive premiums in the area and related environment of the world.
