RAUVOLFIA SERPENTINA [Seeds, Root Cutting & Roots] [Supplier & Exporter]
An erect, green perennial under shrub, 15-45 cm. (rarely 90cm) high; tap root tuberous, soft, sometimes irregularly nodular; bark pale brown, corky with irregular longitudinal fissures; leaves in whorl of three, large, 7.5-17.5cm × 4.3-6.8 cm., elliptic-lanceolate or obavate, acute or acuminate, dark green above and pale green below; flowers white or pinkish, in many-flowered cyme; fruit a drupe, slightly connate, obliquely ovoid, purplish black; pyrenes slightly rugose. R. serpentina can be propagated by seeds, root cuttings, root stumps and stem cuttings. Seed propagation is done by direct sowing of seeds in the field has not been found successful and hence seedlings are raised in the nursery and transplanted in the field. The germination percentage of seeds is very poor and variable (25-50%) and is often as low as 10 percent. This is attributed partly to the adverse influence of the stony endocarp. For propagation root cuttings, large tap roots with a few filliform lateral secondary rootlets are used. Cuttings 2.5-5.0 cm long are planted horizontally about 5 cm. near 50% of the root cutting sprouts in about a month. Propagation by root stumps using about 5 cm of root and a portion of stem above the collar. This method met with about 90-95 percent success or sometime even 100 percent. Stem cuttings taken from woody twigs have also been tried for propagation. Hard wood cuttings have been found better than softwood cuttings; cuttings, 15.0-23.0 cm long having three internodes are most suitable. Soil and Climate : The plant grows in a wide variety of soils. The ideal pH 4.6 -- 6.5. It prefers hot humid climate, humus rich sandy loam soil. A climate with a temperature range of 10 -- 30°C seems to be well suited for this plant. Uses : Sarpagandha is used for the treatment of paranoia, schizophrenia, and hypertension. Propagation : Rauvolfia can be propagated by seed and also by vegetative means like root cutting, root stumps, and stem cutting. Planting : Transplanting of the nursery grown seedlings of 40-50 days. Irrigation : Sarpagandha is cultivated as a rainfed crop. However, 4 irrigations if available in summer and 2 in winter at one month interval may be applied for higher yield. Weeding : Weeding, cleaning, hoeing twice during rains and after rains. Harvesting & processing : The marketable roots are generally collected 2-3 years after plantation preferably after 30 months of planting. Yield : The average yield of Rauvolfia dry root is approximately 1,500 kg/ha under average management when harvested at 30 months.

NURSERY RAISING & PLANTING
The crop can be propagated by seed, stem cutting and root cuttings. Seed propagation is the best method for raising commercial plantation.
By root cutting: Nearly 5 cm long root cutting are planted during spring season closely in nursery beds containing well matured FYM, sand and saw-dust. The beds are kept moist through watering. The cuttings begin to sprout within 3 weeks. These can be planted in field during rainy season after 8 to 10 cm rains are received; the seedlings are transplanted at 45 cm row to row and 30 cm plant to plant distance. In this manner, an estimated 100 kg of root cuttings are found sufficient for planting
one hectare area.
By stem cuttings: Hard wooded stem cutting measuring 15 to 22 cm are closely planted during June in the nursery beds where continuous moisture is maintained.
After sprouting and giving out roots, these plants are transplanted in the main field at given spacing.
By root stumps: About 5 cm of roots, intact with a portion of stem above the collar, are directly transplanted in the field having irrigation facilities.
By seed: Seed germination in Rauvolfia is highly variable. It is reported to vary from 5 to 30 percent even when only heavy seeds are chosen for sowing purpose. Light and heavy seeds can easily be separated by simple water flotation. Germination of heavy seeds during May-June after soaking them in water for 24 hours was 20-40 percent and 62.77 percent germination was recorded in freshly collected heavy seed lot. In all, 6 kg of seeds are sufficient to raise one-hectare plantation.
In Maharashtra and Madhya Pradesh, April end, in West Bengal first week of May or little later, and in Jammu & Dehradun during third week of May are found to be most suitable time for sowing seed in the nursery. The nursery is prepared by raised beds of 10x10 m. dimension under partial shade made up of one-third of well matured FYM and leaf mould, and two-thirds amount medium of silt-loam soil. About 500 sq m. seed bed area is sufficient for raising seedlings enough for planting one hectare land. The seeds sown, 2-3 cm apart in rows in shallow furrows during April end. The furrows are then covered with a fine mixture of soil and FYM. Keep the beds just moist by light watering. Germination starts after 15-20 days and continues up to 30 to 40 days. Seedlings are ready by mid-July for transplanting. The seedlings are transplanted at 30 cm distance within the rows spaced at 45 cm. If rains are not received during or immediately after transplantation irrigation is necessary for better stand. Rauvolfia is long duration (18 months) and slow growing crop particularly in the initial stage; thus different intercrops have been tried.
