The study to determine the interaction between shoot number and method of planting and their effect on cassava production revealed that neither the planting method nor the shoot number significantly influenced the root yield of cassava. Although the result was not consistent in all plantings, single-shoot plants seemed to have the tallest height and produced the most number of leaves per plant. Maintaining the desired number of shoots per plant was observed laborious and expensive. Vertical planting exhibited uniform tuber distribution with reference to the original planting materials. In the study to determine the polarity and optimum depth of planting, all planting showed that the growth and development of cassava was affected by polarity but not by depth of planting. Inverted stakes showed superiority in height, number of leaves and stalk number per plant than the upright or normal planting. However, neither depth nor polarity of planting significantly affected root yield. Deeper planting of stakes resulted to swelling of the original planting materials.
