Directorate of Agricultural Research (DoAR), Province 2, Parwanipur, Bara


Directorate Agricultural Research (DoAR), Parwanipur is the oldest agriculture station of Nepal which was established in 1947 AD (2004 BS) with the name of “Parwanipur Agriculture Farm”. Later on fisheries Development Center was established in 1957 AD (2014 BS) and Horticulture and Central Hatchery (Poultry) units were established in 1959 AD (2016 BS).The National Rice Research Program (NRRP) was also established in 1972 AD (2029 BS) in this directorate. Later in 1998, the NRRP was shifted to Hardinath, Dhanusha.


The RARS, Parwanipur is located in Rampur Tokani VDC ward no. 3 of Bara district and is situated at 11 km. north from country’s commercial city Birgunj, 1.5 km east from National high way near Parwanipur at 27o2′ North Latitude, 84o53′ East Longitude and 115 masl elevation.

The goals of DoAR, Parwanipur is to contribute to the livelihood enhancement of farmers through

  • Enhancing agricultural production and productivity
  • Generating employment and income opportunities for agricultural entrepreneurs
  • Increasing nutritional and food security and
  • Sustainable use of natural resources


  • Assess periodically the agricultural production problems and potential of command area, define and prioritize research agenda in collaboration with commodity research program, central disciplinary divisions, extension services and I/NGOs of the command area.
  • Develop and conduct adaptive and applied problem solving research activities and potential exploration of relevant technologies on-station and on-farm emphasizing farming system perspective with multidisciplinary approach in on-farm research.
  • Generate suitable and stable alternative sets of location specific technologies for sustained and improved agricultural production.
  • Collaborate with central disciplinary divisions and commodity research programs for their multi-location testing, and to obtain specialized technical support.
  • Multiply and maintain breeder and foundation seeds, saplings for mother stock and birds and supply to private seed entrepreneurs, nurseries and animal breeders.
  • Maintain and operate diagnostic laboratories for soil, plant pathology, entomology and animal health to provide diagnostic support service to station research and paid services.
  • Publish research findings of technologies for extensionists and farmers recommendations.
  • Provide location specific technologies to extension services of the command area districts for their dissemination.
  • Establish linkage with private agro-entrepreneurs of command area for obtaining their support for collaborative and contract research.


The researchable problems raised during village level workshop, RATWG meetings are prioritized, designed and formulated in the form of proposal/research projects by interdisciplinary research teams involving scientists and technicians from relevant discipliners and of station itself. These research projects are conducted on stations and at outreach sites.

Technical Programs

While working in a multi-disciplinary facet on crops, horticulture, fisheries and poultry, the technical programs of Parwanipur are broadly classified into followings:

On-station Research

The on-station research projects are developed by the scientists to address regional problems. These are mostly applied research programs. The on-station research activities are of two types

Regional Programs

The research projects are developed by station scientists to address regional problems raised during RATWG.

Collaborative Programs

These are projects developed by commodity programs and disciplinary divisions to address regional/national problems. Research projects on rice, maize, grain legume, oilseed, potato, wheat variety development, forage and pasture are collaborated by station scientists of respective discipline to address national problems.

Mostly genotypes of different crops are evaluated to select elite materials suitable for solving regional/national needs, system research, nutrient management etc.

Outreach Research

In the outreach research, the scientists develop and conduct research activities to verify developed technologies in the farmers’ fields of the command area with active participation of farmers, extension workers and I/NGOs. The activities also include training of extension workers and farmers, surveys and prioritization of the problems, program planning and monitoring. At present DoAR, Parwanipur have four outreach sites in its command districts.

Production Program

DoAR, Parwanipur also produces foundation seeds of cereal, legume, oilseed and vegetable crops, fruit saplings, fish fingerlings and avian chicks for dissemination of improved varieties/breeds in the region and other parts of the country.

Technical Services

The scientists also help clients in solving soil fertility problems, insect pest identification and management, technical advice to farmer’s and extension workers to facilitate agricultural development in the province.

Current thrust areas for research

  • To conduct basic, adaptive and applied research on crops, horticultural crops, fisheries and poultry for developing economically viable and sustainable package of technologies to reduce poverty by increasing agricultural production.
  • To conduct on-farm research for verification of the generated technologies in the command area in order to suit farming system and socio-economic domains.
  • To maintain selected genotypes of plants, poultry and fish and to produce source seeds/saplings of improved varieties of plants, hatchlings and fingerlings of fishes and chicken of avian birds for the clients.
