The experiment was conducted at the Horticulture Field Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University during December 2007 to July 2008 under upland condition to observe the seed production potentiality of Eryngium foetidum at different spacing. Individual plant performance, flower stalk size, number of inflorescence, seeds/inflorescence and thousand seed weight were higher in wider spacing but marketable fresh yield and seed yield per unit area was better in medium (10×10 cm) spacing. The spacing 10×10cm gave the maximum profitability including fresh plant and seed yield. The maximum fresh yield was obtained from 15×15 cm spacing (16.23 t/ha) while the highest seed yield was recorded in 10×10 cm spacing (136.3kg/ha). The maximum gross return (Tk. 0.75 million/ha) and BCR (4.76) were obtained from 10×10 cm spacing.

Variety and Species
To investigate seed production potentiality with different plant spacing.
The experiment was conducted during December 2007 to July 2008 at the Horticulture Field Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur situated in the middle part of Bangladesh (24000’N Lat. and 90026’E Long.). The experimental field belonged to AEZ-28 and the soil was Brown Terrace but modified (through land development) to medium loamy to moderately fine texture (sandy clay loam). The experiment was laid out in a randomized complete block (RCB) design having nine treatments with three replications. The unit plot size was 3×1 m. The treatment combinations were - T1: Broadcasting and no thinning, T2: 10×5cm, T3: 10×10 cm, T4: 15×5 cm, T5: 15×10 cm, T6: 15×15 cm, T7: 20×5 cm, T8: 20×10 cm and T9: 20×15 cm. The experimental land was fertilized with decomposed cowdung @ 15 t/ha, 200 kg-N, 120 kg-P and 150 kg K. Days required for flower stalk emergence, flowering, seed browning and seed blacking was counted daily observing the plants and inflorescence carefully. Flower stalk/m2, number of inflorescence per flower stalk, number of seeds per inflorescence were recorded from 10 plants from each plot. Thousand seed weight and weight of seeds (g/plant) were recorded from the harvested seeds of 10 plants after sun drying and cleaning of seeds.

Individual plant performance, flower stalk size, number of inflorescence, seeds/inflorescence and thousand seed weight were higher in wider spacing but marketable fresh yield and seed yield per unit area was better in medium (10×10 cm) spacing. The spacing 10×10cm gave the maximum profitability including fresh plant and seed yield. The maximum fresh yield was obtained from 15×15 cm spacing (16.23 t/ha) while the highest seed yield was recorded in 10×10 cm spacing (136.3kg/ha). The maximum gross return (Tk. 0.75 million/ha) and BCR (4.76) were obtained from 10×10 cm spacing.
Medium spacing (10×10 cm) was more profitable due to higher marketable fresh yield and seed yield valued more gross return as well as gross margin because the variable cost in all spacing and broadcasting was similar. In broadcasting and wider spacing sowing cost was little less than closer spacing but weeding cost was higher in these two cases resulted similar variable cost finally.
