Abstract

Post-harvest enzymatic activities of healthy and infected Cassava (Manihot esculenta Crantz) tubers

Highlights

  • Cassava (Manihot esculenta Crantz), is among the prominent tuber crops in the tropical and subtropical world while Nigeria is currently one of the largest world producers

  • Lasiodiplodia theobromae and Rhizopus stolonifer had the highest percentage of pathogenic indices (96%) followed by Macrophomina phaseolina and Fusarium pallidoroseum with 83% and 80% respectively and least was Penicillium spp.(5%) (Table2)

  • Occurrence and activities of some micro-organisms causing rot disease of some staple food crops especially tubers are becoming menace and thorn in the flesh of the movement for food security in the tropics. This has been established in this study when surveys on the importance of microorganisms causing rot disease of cassava tubers in storage were conducted in three states of Southwestern part of Nigeria

Summary

Introduction

Cassava (Manihot esculenta Crantz), is among the prominent tuber crops in the tropical and subtropical world while Nigeria is currently one of the largest world producers. It is grown for its starchy tuberous roots which can be used for the production of ethanol, glucose, starch, alcohols, gums and pastes for industrial uses (Adewolu, 1999). It is a valuable source of calories, for low-income earners (IITA, 1990). Cassava contributed 14% of the average daily dietary energy intake per person in Nigeria, the fourth largest contributor after sorghum (22%), millet (19%), and yam (15%) (FAO, 1991) as quoted by Felix et al (1999)
