Abstract

Survey of available warehouses and silo structure for storage in humid parts of South Western Nigeria was done to assess the factors and problems associated and affecting grain quality deterioration in these large scale storage structures. A questionnaire was administered for the study to identify the types of large scale storage structures used in South Western Nigeria, and the management problems associated.

Good quality grains were only accepted for storage after thorough examination in most establishments. Manipulation of the storage environment by controlled atmosphere has retard grain quality degradation and possesses good seed viability and consumer friendly. Silo capacity ranges between 5 to 2,500 metric tonnes while ware houses are between 200 to 5.000 metric tonnes. Modern storage structures ages are between 10 to 46 years within this region.

The predominant environmental problems of conventional silos were ambient temperatures fluctuations and high relative humidity.
