- Abstract
The hygroscopic nature of maize seed enables it to absorb atmospheric moisture. This sometimes makes them unsafe for storage especially in the tropics that is characterised by high humidity and temperature. An experiment was therefore conducted at Institute of Agricultural Research and Training, Obafemi Awolowo University, Moor Plantation, Ibadan, Nigeria, during the dry and wet seasons of 2006 and 2007, to investigate the effects of storage materials and storage environment on maize seed drying during storage, and to test their resultant effects on seed germination. Seeds of five cultivars of maize, popularly grown by farmers in South Western Nigeria were stored in two storage materials (polyethylene and hessian sack bags) under ambient conditions of Abeokuta (Rain forest ecology), Ballah (Southern Guinea Savannah ecology) and Ibadan (Derived savannah ecology) for 180 days during dry and wet seasons. Results from the study revealed that maize seed deterioration could not be absolutely avoided over time regardless of the storage materials used, but the rate can be reduced if adequate attention is given to storage environment, such as % relative humidity, temperature and initial moisture percent (%) of the seed. Storage environment and materials significanly affected drying of maize seed during storage while storage environment and season of storage determines the choice of suitable materials for storing maize seeds. Polyethylene bag appeared to be most suitable for storing maize seed during wet season, in all the locations, while hessian sack bag is recommended for storing maize seed during dry season.
