Agro-technique

Nursery Technique

  • Raising Propagules: Cuttings may be planted in raised beds at 10 cm apart row and 5 cm within a row. Double node stem with leaves is recommended for planting in the month of August and September. Seed germination is low around 25-30%.
  • Propagule Rate and Pretreatment: 22,400 cuttings/ha are required. Growth hormone like IBA may be used for early sprouting.

Planting in the Field

  • Land Preparation and Fertilizer Application: Land should be prepared to fine tilth before planting. FYM @ 15- 20 t/ha can be applied for good initial growth. NPK @ 100:50:50 kg/ha may be applied by broadcasting. A dose of nitrogen based fertilizer at 40 kg may be applied after each harvest.
  • Transplanting and Optimum Spacing: Best time of transplanting sprouted cuttings is during September in Assam. Staking is to be provided when it attains a height of 90 cm or over. Optimum spacing is recommended at 60X60 cm.
  • Intercropping System: Winter vegetables may be grown as intercrop.
  • Interculture and Maintenance Practices: Hoeing along with weeding, is necessary at 45 days after planting; thereafter, once in a year.
  • Irrigation Practices: It is a rainfed crop in Assam.
  • Weed Control: Weeding is done at 60 and 90 days after transplantation. However, where-ever pre-emergence weedicide like simazine @ 2.0 kg/ha, or oxyflurefen@2.0 kg/ha is applied, the weeding could be delayed to 120 days and thereafter after each harvest.
  • Disease and Pest Control: No pest and diseases have been observed in the trial plantation.

Harvest Management

  • Crop Maturity and Harvesting: Crop matures after six months. First harvest of vines can be done at 6 months (March-April) from the date after transplantation; thereafter, at 4 months interval (July-August and October-November). Winter harvesting is not advisable.
  • Chemical Constituents: Plant contains friedelan-3-one, β-sitosterol and epifriedelinol; the leaves and stem gave iridoid glycosides – asperuloside, paederoside and scandoside; sitosterol, stigmasterol, campesterol; ursolic acid, hentriacontane, hentriacontanol, ceryl alcohol, palmitic acid and methyl mercaptan.
  • Yield: Yield 1.2 t/ha (Dry weight basis) annually.
