Climate and Soil
- Plant grows in open waste lands over sandy-saline lands in low rainfall areas.
- Seeds can be directly sown in field.
- Raising Propagules: Seedlings of crop could be produced through planting of transition zone cuttings of the plant in the main field during September-March.
Planting in the Field
- Land Preparation and Fertilizer Application: The field is ploughed and harrowed well, to make a fine tilth. The crop responds well to the basal application of nitrogenous fertilizer.
- Sowing of Seeds and Optimum Spacing: Fresh seeds collected during October-March are directly sown in rows in the field. The spacing of 90 cm plant to plant and 120 cm row to row, gives optimum crop stand of 5000 plants/ha.
- Inter cropping System: No information available.
- Irrigation Practices: Rainfed crop, irrigated when required.
- Weed Control: Two manual weedings are required at an interval of one month each after the crop is 40 days old.
- Disease and Pest Control: No disease and pests have been noticed in trial plots.
- Crop Maturity and Harvesting: The crop is manually harvested at flowering stage when chemical contents are maximum.
- Post-harvest Management: The harvested crop is shade dried and stored in gunny bags in air-cooled rooms for marketing.
- Chemical Constituents: Plant contains choline, pluchine taraxsterol, β- and g -sitosterol, leaves give quercetin and iso-rhamnctin.
- Yield : An average crop produces 40 t/ha of dry herb.
