Abstract

This study was undertaken to calibrate open seed warehouse storage environments in the humid tropics and model maize seed deterioration under them. Five maize varieties (TZPBSR, DMR-ESR-Y, Oba Super-2, Suwan-1-SRY, and ART-98-SW1) were used for the study. The seeds were cleaned and their initial quality determined by recommended methods. One kilogramme of seeds of the five maize varieties were packaged in separate moisture-proof polythene bags (with automatic thermohygrometers inserted to monitor changes in temperature and RH) and placed in the seed stores at the University of Agriculture, Abeokuta (UNAAB) and the Institute of Agricultural Research and Training, Ibadan (IAR&T) from 2005-2007. Seed samples were taken at 3month interval and evaluated for seed viability and seedling vigour attributes. Probit analysis was used to estimate seed deterioration and potential longevity. PROC GLM statement of SAS was used to separate means of variables evaluated in both environments. The seed survival curves under the humid tropical conditions fitted the normal distribution curve well (3(4): >0.05); with UNAAB seed storage environment extending the longevity of stored seeds far better than the IAR&T seed store. Overall, results showed that effective seed storage under humid tropical conditions is possible, though effectiveness may differ from one environment to the other.
