The plant requires slightly acidic to neutral soils for good growth with medium to deep well drained fertile soils. Clay-loam to silt-loam soils, rich in organic contents are suitable for its commercial cultivation. It grows well in frost-free tropical to subtropical situations under irrigation.
Basic Steps For Sarpagandha Cultivation
The plant can propagate by three ways like from seeds, from root cutting, and from stem cuttings.
First of all, you can collect the ripe seeds from the beginning of June to the end of October. then retain their viability for six months. Sow the seeds in raised beds at a depth of 1cm in the nursery in lines 10cm apart with 5cm distance from seed to seed. You can sow about 5.5kg of seeds in 0.05 ha area of the nursery. It ensures an adequate number of seedlings to plant one hectare. The seeds germinate within three weeks.
You can use the large tap roots, as well as lateral secondary rootlets, for preparing the cuttings of 2.5-3.0cm. Plant them in holes of 5cm deep at the advent of monsoon and covered with the 2.5 to 5.0 cm top layer of soil. If you maintain good moisture, then the cuttings sprout within three weeks of time duration.
You can plant stem cuttings of 15 to 20cm length with three internodes in the month of July-August in the nursery and keep it moist. They strike roots within 60 days. After that, you can transplant them to the main field.
Plough the deeply and left for weathering. After pre-monsoon showers, add FYM. Do the second ploughing and two cross harrowings to break the clods. Finally, dress the land by planking and layout the beds. You must raise the nursery in a partially shaded area with adequate irrigation facility. Each bed must have about 1.5 m wide, 150-200 mm high and of convenient length. Beds with shallow furrows 80-100 mm apart are prepared in April and irrigated.
June and July are suitable months for transplanting seedlings and vegetatively propagated plants. The seedlings, which are 7.5-12.0cm high, are carefully dug out from nursery beds and planted. You must go for regular irrigation, weeding, and manuring for optimum growth.
It is always better to use organic manure. Additionally, you can apply a basal dose of 20kg nitrogen (N), 30kg phosphorus (P2O5) and 30kg-potash (K2O) per hectare. Also, you can apply two top dressing of 20kg annually during the growing season.
You must provide irrigation at regular intervals. In hot dry season, irrigate the crop fortnightly and once a month during winter.
First of all, you must keep the field relatively weed-free in the initial period of growth. This means giving two to three weedings and two hoeings in the first year are important. Two weedings in the first year and one weeding in the second year followed by one hoeing usually at the beginning of the growing season are required. If you notice appearing flowers on very young plants, nip them to promote root growth.
Plant protection is an essential aspect in the cultivation. You must provide proper plant protection to avoid severe damage. Generally, caterpillars roll the leaves and feed on tender leave and cause defoliation. Additionally, Die back disease is very common in Sarpagandha cultivation.

You can obtain about 2000 kg of dried roots from one hectare.
Drying & Keeping Sarpagandha Roots
