Agro-technique 

Nursery Technique

Raising Propagules:  Seeds are sown in raised nursery beds during June after rains and seedlings later transplanted on ridges in well laid out plots.

Seed Rate and Pretreatment:  About 4 kg seed may be needed for raising seedlings for planting on one hectare of area. No specific pretreatment of seed is recommended.  
  
Planting in the Field

Land Preparation and Fertilizer Application:  The soil should be ploughed, harrowed and plucked and made into a fine tilth. 20 tonnes of FYM is applied during land preparation. For nursery beds, farm yard manure at the rate of 10 t/ha is mixed in the soil along with 100 gm Azospirillum + 100 gm Phosphobacteria + 100 gm Trichoderma as basal medium.  In main field 25-30 t/ha of FYM is applied as a basal medium + 2.5 kg Azospirillum + 2.5 kg Phosphobacteria is given before transplantation. 

Transplanting and Optimum Spacing: 15-20 days old seedlings of 8-10 cm height are transplanted at 30 cm distance in rows in the field immediately after the first monsoon shower.  If there is no rain; the field should be irrigated immediately after transplantation. For one hectare area about 4.0 lacs seedlings are needed at an optimum spacing of 25X25 cm.

Interculture and Maintenance Practices: The crop needs hand weeding at 30 and 60 days interval after planting.

Irrigation: Irrigation is required during dry season if monsoon rains is scanty.  The frequency of irrigation depends on the moisture content of soil.

Disease and Pest Control:  Powdery mildew disease occurs during rainy season. This is controlled by spraying biopesticides like Azadirachtin, Trichoderma viridie, Pseudomonas cholotorapsis etc.

Harvest Management

Crop Maturity and Harvesting:   The crop matures in 80-90 days when it should be harvested; it has maximum active chemical ingredients at fruiting. However, seeds collection is done after 110-120 days old crop. 

Post-harvest Management:  Whole plant is pulled manually and shade dried. The dried herb is stored in polythene lined gunny bags at cool, well ventilated godowns.

Chemical Constituents:  The herb contains three crystalline lignans including phyllanthine and hypophyllanthine (non-bitter part).  In addition, five flavonoids have been identified viz. quercetine, astralgin, quercitrin, isoquecitrin and rutin.  Four alkaloids have also been separated.  The total phyllanthin lignans range between 1 to 1.2% in the dry herb.

Yield and Cost of Cultivation:  A yield of 2 to 3 t/ha of dry herb is obtained.   Rs-27,500/- is the cost of cultivation for one hactare.
