Seed viability and germination retention using physical factors and chemicals treatments was studied at the Seed Technology Division, BARI, Gazipur during July 2010 to June 2011. Treatment of seeds with growth regulator and soaking and drying of seeds enhanced seed germination in the field and laboratory. Consecutive 96 hours soaking and drying (8 hours soaking and 4 hours drying) of Bangladhonia (Eryngium foetidum L.) seeds treated with GA3 500 ppm and Kinetin 50 ppm gave the maximum germination percentage (74.7%) and enhanced germination (12.0 days in lab.).

Variety and Species
i) To increase the germination rate and prolongation of seed viability in Bangladhonia.
ii)To increase farmer’s profitability decreasing the production (seed) cost in cultivating Bangladhonia.
The experiment was conducted at Seed technology Division, BARI, Gazipur during July 2010 to June 2011. The experiments comprised with two different factors such as growth regulator treatment and soaking duration
Germination test were conducted in normal room temperature with eighteen treatment combinations of two factors viz. three seed treatment comprising growth regulator (GA3 500ppm + Kinetin 50 ppm), pesticide (copper oxi-chloride 0.2% + tetracycline 1000 ppm) and control (distilled water) with six soaking levels viz. 0, 12, 24, 48, 72 and 96 hours soaking with 8 hours consecutive soaking and 4 hours drying was used in the experiments. 100 seeds were placed in each Petridis that treated as unit treatment and replicated three times.

Growth regulator treatment (GA3 500 ppm and kinetin 50 ppm) with 72 to 96 hours soaking (changing water at 8 hours intervals) gave the highest seed germination of Bangladhonia that reduced the about 75% seed rate as well as seed cost. Better germination ensured optimum number of plant per unit area resulted higher yield and economic return that increased profitability.
