Abstract
Seeds deteriorate rapidly during storage under humid tropical conditions of high air temperature and relative humidity. This deterioration is reflected by physiological changes in the seed system, which is manifested in form of decline in seed viability and seedling vigour. This study was undertaken to examine the potential of dried charcoal as a low input and cost effective storage method under humid storage conditions. Soyabean seeds placed in sealed polythene bags of 700 gauges with various levels of charcoal dessicant to seed ratio and stored under ambient tropical conditions were evaluated for seed viability and seedling vigour attributes. The results showed that seed preservation was optimal under desiccant to seed ratio of 1:2 with a half life (P50) of 101 days. This can be effectivey used as an alternative sealed-dry storage method for soyabean seed under ambient conditions in humid tropical regions.
