Effects of different sowing methods, seed rate with growth regulator treatment were evaluated to reduce seed rate and cost of bangladhonia (Eryngium foetidum) production. Broadcasting or line sowing in closer spacing (10 cm) with hormone (500 ppm GA3 + 50 ppm Kn) gave the maximum yield and benefit with 20 kg seeds/ha. The highest number of seedlings (1891/m2) and harvested plants (1212/m2) were obtained from broadcasting of growth regulator treated 30 kg seeds/ha. The maximum fresh plant yield (53.34 t/ha), gross return (Tk. 1.33 million/ha), gross margin (Tk. 1.18 million/ha) and BCR (8.52) were found from broadcasting sowing with growth regulator treated 20 kg seeds/ha.

Variety and Species
To increasing the seed germination with the application of growth regulators for lowering the seed rate to maintain an acceptable yield potentiality in bangladhonia.
The experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during December 2007 to July 2008. The pH of the experimental soil was 5.9. The experiment was laid out in split plot design with three replications. Three sowing methods (T1: Broadcasting, T2: Line sowing 10 cm apart and T3: Line sowing 15 cm apart) were assigned in the main plot, three seed rates (S1: 10 kg/ha, S2: 20 kg/ha and S3: 30 kg/ha) were placed in sub-plots or unit plots. Seeds were treated with growth regulator (500 ppm GA3 + 50 ppm Kn) solution. The experimental land was fertilized with decomposed cow-dung @ 15 t/ha, 200 kg N, 120 kg P and 150 kg K (Islam et al. 2003). Seeds were mixed with coarse sand and sown on 11th December, 2007. Broadcasting (T1) is the traditional sowing system of bangladhonia where line spacing was not maintained. The other two line spacing of 10 cm (T2) and 15 cm (T3) were maintained by making small furrows (2 - 3 cm width and 1.0 - 1.5 cm deep). Seeds @ 3, 6 and 9 g per plot (3 m2) were sown for 10 (S1), 20 (S2) and 30 (S3) kg/ha seed rates, respectively. Flower stalks were removed to get larger succulent leaves. Harvesting of longer succulent plants was done from the last week of May to the second week of July with an interval of 20 days. Data on days to germination, number of seedlings, harvested plants/m2, plant weight and fresh yield were taken from each harvest in every plot.

The highest number of seedlings (1891/m2) and harvested plants (1212/m2) were obtained from broadcasting of growth regulator treated 30 kg seeds/ha. The maximum fresh plant yield (53.34 t/ha), gross return (Tk. 1.33 million/ha), gross margin (Tk. 1.18 million/ha) and BCR (8.52) were found from broadcasting sowing with growth regulator treated 20 kg seeds/ha.
20 kg seed/ha with GR (GA3 500 ppm and kinetin 50 ppm) treatment plus broadcasting or line sowing at 10 cm apart were found better for higher yield as well as profitability in bangladhonia (Eryngium foetidum L.) cultivation.
