Abstract

The objectives of this experiment were to study the effects of photoperiods, hormone, and phosphor on the increases of quality and longevity of soybean (Glycine max L. Merr.) seeds. The experiment was conducted both during dry and wet seasons at Sebapo Experimental Station, Jambi and Center for Post Harvest Research and Development, Bogor from November 2009 until November 2010. The experiment used factorial split split plot designed which consisted of three factors, i.e. photoperiod (12 hrs and 14 hours 54 minutes) as the main plot, concentrations of IAA (0, 75 and 150 ppm) as sub plot, and dosages of phosphor (0, 60 and 120 kg P2O5 ha-1) as sub sub plot. The parameters being observed included seed quality (carbohydrate, protein and lipid seed content) seed viability and vigor after storage for three months at room temperature and respiration rate during storage. The results showed that treatment of photoperiod 14 hours 54 minutes, IAA 75 ppm and P2O5 120 kg ha-1 increased seed quality and longevity indicated by the increased of soybean seed yield from 4.07 to 14.21 g plant-1; increased protein, carbohydrate, and lipid content to 40.15, 32.23 and 14.21% respectively; increased seed longevity during storage at room temperature (seed viability before and after 90 days stored at room temperature were 97 and 90.77% respectively; rate of germination were 41.33 and 33.12%KN etmal-1 respectively; and decreased respiration rate during storage (only 0.683 ml CO2 kg seed-1 hr-1). Seed quality and longevity which were produced during dry season were much better compared to wet season. Good agronomic practices resulted in increasing not only yield but also the quality and longevity of soybean seed during storage.
