Rokupr Agricultural Research Centre
ROKUPR AGRICULTURAL RESEARCH CENTRE- ROKUPR
Background
The Sierra Leone Agricultural Research Institute (SLARI) is mandated to implement the agricultural policies and strategies of the Government of Sierra Leone. To fully perform its mandate the Institute has adopted a programme approach to its research planning and management. Administratively, the research programme areas of focus corresponds to the seven research Centres that constitute the Institute.
One of the Centres is;
ROKUPR AGRICULTURAL RESEARCH CENTRE- ROKUPR
Has the mandate to coordinate and implement research programmes in the area of cereal crops including the country’s staple rice, sorghum, maize, Digitaria and pearl millet.
The Rokupr Agricultural Research Centre-Rokupr is one of the constituent research Centres of Sierra Leone Agricultural Research Institute (SLARI) mandated to conduct research on cereal crops including the country’s staple rice, maize, sorghum, Digitaria and pearl millet.
The Centre was established in 1934 as the West Africa Research Institute (WARRI) and was the beacon of rice research in Anglophone West Africa before the era of independence. During this period, the Station serves as the Centre for research on rice for English speaking West Africa. In post- independence Sierra Leone, WARRI became the Rokupr Rice Research Station (RRRS) with a mandate for research on all rice ecologies (Upland, Inland Valley Swamps, Bolilands, Mangrove Swamps and the Riverine) in Sierra Leone.
Between 1964 and 1971, RRRS was attached to the faculty of Agriculture, Njala University College and in 1971, RRRS assumed a semi-autonomous Institution with a Board of Management and a Director. Rokupr was one of the two institutions of the National Agricultural Research Coordinating Council (NARCC) in Sierra Leone established in 1984.
In 2007, and by an Act of Parliament, it was transformed to the Rokupr Agricultural Research Centre (RARC) under the Sierra Leone Agricultural Research Institute (SLARI). After a review of the 2007 SLARI act, the Centre was renamed to date the Rokupr Agricultural Research Centre-Rokupr (RARC-Rokupr)
LOCATION
The Headquarters of RARC-Rokupr is at Rokupr town in the Magbema Chiefdom, Kambia District, 20 nautical miles from the Atlantic Ocean along the Great Scarcies and 112 miles from Freetown by road. RARC-Rokupr also operates Out-Station Crop Sites at Blama, Bo, Torma Bum and Gbomsamba.
ORGANIZATION
Work in the Centre is organized in programs including:
- Crop Improvement – comprising crop breeding, seed technology units.
- Soil, Crop Management & Natural Resources – comprising, Soils, Agronomy, Physiology, Pathology/ Virology, Entomology, Vertebrate Pest Units and Analytical services laboratory.
- Engineering, Post- harvest & Food Technology – comprising Agricultural Engineering, Nutrition and Farm Management Units.
- Socio- Economics, Policy Research & Outreach – comprising Agricultural Extension, Agricultural Economics, Sociology, Gender and Outreach Units.
And three support division: – Administration, Estate and Accounts.
OBJECTIVE
To generate and promote innovative technologies for cereal crops (Rice, Maize, Sorghum, Millet and Digitaria) and empowerment of stakeholders along the cereal value chain.
CENTRE PROGRAMME FOCUS
At RARC, research on rice and other cereal crops is centered on the Agricultural Produce Value Chain and focused on all five different agro-ecologies in the country. The cereal program focuses on six product value chains:-
- Development and promotion of Upland rice product value chain.
- Development and promotion of Lowland rice product value chain.
- Development and promotion of Maize product value chain.
- Development and promotion of Sorghum product value chain.
- Development and promotion of Pearl millet product value chain.
- Development and promotion of Digitria product value chain
MAIN PRIORITIES AND THRUSTS
Research priorities focus on problems connected with sustaining and increasing yields of rice and other mandate crops under normal and stressed conditions in the country.
The principal thrusts are to sustain the quality of agricultural lands, to develop the knowledge based that could enable farmers to maximize their economic efficiency and profitability in production, processing and marketing of crops of the cereal based cropping systems in Sierra Leone.
NATIONAL & INTERNATIONAL COLLABORATION
At the National level, the Centre has strong collaborative links with the Ministry of Agriculture, Forestry and Food Security (MAFFS), Njala University, University of Sierra Leone, and NGOs involved in Agricultural Research and Extension.
Internationally the Centre has strong ties with the AfricaRice, the International Institute of Tropical Agriculture (IITA), International Rice Research Institute (IRRI), the International Crops Research Institute for the Semi-Arid Tropics (ICRSAT), International Atomic Energy Agency (IAEA), CORAF, and JICA.
The Government of Sierra Leone is the main source of the Centre funds. Through the Sierra Leone Government and the Development partners, RARC-Rokupr receive some funding and technological support from AfricaRice, World Bank/Japan Government-West Africa Agricultural Productivity Programme (WAAPP), International Institute of Tropical Agriculture (IITA), International Atomic Energy Agency (IAEA) and NGOs for collaborative research Projects.
Since its establishment in 1934, a lot of research work has been done for the development of rice technologies in the mangrove swamps and other rice ecologies. Over the last 10 years, some major accomplishments of direct benefit to both the local farming community and the International scientific community include:-
- Rice Value Chain Analysis in Sierra Leone
- Elucidation of the basic chemistry of mangrove swamp soils for profitable rice production.
- Demonstration of the efficiency of Mechanical cultivation with the single axle tractor in mangrove swamps for increasing rice growth yield.
- Response of Deep placement of Urea super granule in Mangrove swamps
- Use of Buta Force herbicides and Rotary weeders to control weeds in the IVS, Boliland and Associated mangrove swamp rice ecologies .
- Development of low cost methods for ameliorating iron toxicity in the lowlands with ashed rice husk.
- Characterization of Tidal Mangrove Swamp and Riveraine Grassland Ecologies in Sierra Leone
- Cost benefit analysis of rice production in Sierra Leone
- Establishing optimum time for single hand weeding and nitrogen application to produce higher net benefit in rice cultivation.
- Modified System of Rice Intensification (SRI) for rice cultivation in the in the IVS and Boliland.
- Fabrication of Improved threshing and parboiling equipment.
- Farmer’s indigenous knowledge system and practices affecting rice production.
- Farmers demand for improved rice seeds.
- Developed post- harvest technologies for maximum net grain yield; longer shelf life and nutritive value of rice.
- Rice technology transfer through training, on-farm trials, demonstrations and consultancies.
- Breeding and release high yielding, adaptable rice varieties for upland and lowland ecologies as given below;
- Released upland rice varieties ROK 3, ROK 16, ROK 17, ROK 20, ROK 34, NERICA 3, NERICA 4, NERICA 6, NERICA 15, NERICA 16, NERICA 18
