**4. Conclusion**

Conclusively, suggested way outs should be given utmost attention, most especially research efforts should be geared towards utilization of lesser known non conventional crops as sources starch such as wild yams. Sufficient to say, the current level of research on wild yams starches, such *Dioscorea villosa*, *Dioscorea bulbifera* and other lesser known starchy crops is limited. Therefore, the properties and potential utilization of starch obtained from *D. villosa*, *D. bulbifera* and other lesser known starchy crops should be established in order to broadening the present narrow commonly cultivated starch sources. Also, value addition and conceptual efforts towards good agricultural practices might enhance the productivity of conventional starch sources such as cassava and maize.
