Abstract
This study aimed at comparing the relative effects of wet and dry heat seed treatments on some important agronomic qualities of Corchorus olitorius. The experiments were carried out in Babcock University soil lab and Screen house. The Corchorus seeds were exposed to Wet heat (Hot water) and Dry heat (Oven), fifty grams seeds of Corchorus olitorius was separately soaked in 60oC, 80oC and 100oC of distilled water for 2, 4 and 6 minutes respectively. The same numbers of seeds were placed in sterilized non-disposable (Pyrex) Petri dishes and kept in the oven at 60oC, 80oC and 100oC for 2, 4 and 6 minutes. Data was collected into three main grouped variables which are Agronomic Variables- Plant Height, No of leaves, Leaf length, Leaf width, Plant height at flowering, Seed Viability and seedling vigor Variables- Germination count, Fresh leaf weight, stem weight and total plant weight, Yield Variables- Capsule length, Capsule width and One thousand seed weight .The experiment was a 2x3x3 factorial experiment and it was setup using a completely randomized design with three replications. Results shows that the interactions were significantly different for germination count and seedling vigour index for seed viability and seedling vigour variable, for agronomic characteristics, interactions were significantly different for only capsule width. In this present study, wet heat at 80oC for 2mins(94%) shows to be the most effective treatment combination and Dry heat at 80oC for 2 minutes (6%) shows to be the less effective treatment combination in terms of germination and seedling vigour. Germination and seedling vigour were initiated at 60oC, and the optimum germination and seedling vigour was obtained at 80oC after seed were exposed to 2 minutes of wet heat treatment. Optimum seed germination and seedling vigour index were obtained at 80oC in the treatment combination. The study concluded that wet heat treatment at 80oC at 2minutes can be used to obtain optimum seed germination and seedling vigour of Corchorus olitorius and this easily be adopted by small scale farmers.
