Highlights of Some Achievements

Improve R&T Varieties 

In 2009, CSIR-CRI released 4 high yielding and drought tolerant cassava varieties. Another six varieties of cassava developed from local landraces in were released in 2014 giving a total of 10 high yielding cassava varieties released in the space of 5 years. The Research Institution has also released 3 varieties of cocoyam and 4 varieties of sweet potato. All the released varieties of Root and Tuber crops were done with support of the West Africa Agricultural Productive Programme ( All the released varieties have the potential of increasing cassava yields by more than 40%.

The Yam Vine Technology

The yam vine technology to enhance yam seed production which is slow under the minisett technique. This technology uses yam vine to rapidly produce seed yam. The technology has a seed yam multiplication ratio of 1:240 as against the conventional minisett method of 1: 4.

Rapid Multiplication of Planting Materials using Biotechnology

The CSIR-CRI has been using biotechnology in various areas of crop production to support the rapid multiplication of planting materials of crops. The institute has used biotechnology to develop 20 SSR markers for cocoyam. Also, with the support biotechnology three improved yam varieties have been genotyped while DNAs of 12 new varieties of sweet potato has been initiated for extraction. Eight varieties of rice have successfully isolated using biotechnology. CSIR-CRI is also using tissue culture to rapidly multiply yam, cocoyam, cassava and sweet potato planting. A Number of R&T crops are at various stages of in vitro multiplication.

The CSIR-ARI developed an intensive and semi intensive guinea fowl resource centres used for the training of guinea fowl farmers on good practices in guinea fowl production in order to boost the production of guinea fowls in Ghana. The brooder houses have the capabilities of reducing guinea keets mortalities by more than 80%. Guinea keets mortality is a major problem affecting the guinea fowl production industry. The Institute has also working on trials of using ethnobotanicals for treating diseases of livestock.

As part of the Council’s contribution to addressing the country’s food security problem, the Savannah Agricultural Research Institute has released 4 early maturing (90 days to mature) and medium maturing (100 – 110 days), drought/Striga tolerant hybrid Maize. They are Kunjor-Wari, Suhudoo, Wari-kamana and Kpari-faako. These hybrid maize varieties are adapted to all the agro-ecological zones of Ghana and more especially to the savanna ecological zone that are challenged with such stresses as drought and striga infestation. The newly released varieties have yields potentials of between 5.7 and 5.8 t/ha for the early maturing hybrids and between 6.7 and 6.9 t/ha for the medium maturing.

Another drought tolerant maize; Pannar, also a hybrid variety has been released in addition to the 4. Pannar has a yield potential of 5.8t/h under favourable condition and 3.8t/ha under drought and climatic stressors. The released hybrid variety is also tolerant to rust and blight and had significantly higher yields than the three (3) local hybrids and Obatanpa under favourable conditions and even under drought stress.Additionally, the Savannah Agricultural Research Institute has released 5 improved varieties of pearl millet, namely; Bristled, SO x SAT, Tongo Yellow, Arrow and Bongo Short Head. Three of the varieties were developed from three major crosses of local and exotic pearl millet varieties resistant to bird attack, downy mildew, smut and ergot diseases.

Post-Harvest Technologies

The Food Research Institute of the CSIR has developed technologies for processing three (3) intermediate products of cassava (High Quality Cassava Flour, Grits/Chips and Gari) and transferred to a number of processors. So far 2,500 primary out-processors have adopted these technologies. The institute has also developed and transferred technologies for utilizing composite flour from yam, cocoyam and sweet potato for adoption by bakery enterprises. The use of composite floor for baking will save the country a lot of foreign currency from the importation of wheat floor. In order to ensure the adoption of these technologies and to promote agribusiness activities, an agribusiness incubation centre was established.

Technologies for using composites flour to produce bread, biscuits, queens’ cake, chips, meat pie, chinchin and doughnuts from yam, sweet potato, cocoyam and water using the following combinations (10, 20, 30, 40, 50%) have been developed. Additionally, composite flours of cassava, sorghum, rice and maize have been formulated on 5, 10, 15, 20, 30, 40 and 50% into bread, chips, meat pies, biscuits, cakes and doughnuts. The adoption of composite flour by the bakery industry as a substitute to wheat flour will help cut down the importation of wheat flour.

The Building Roads Research Institute of the CSIR Designed and Constructed a timber Bridge using secondary timber species. The bridge cost 75% of an equivalent concrete or steel bridge. The life span of the bridge is 50-60 years equal to concrete bridge and it is design to carry 60 tons load. The institute has also identified 85 termite-resistant timber species suitable for construction. One of the important breakthroughs was the development of Pozzolana which replace cement up to 40% thereby reducing the cost of cement by 18-20%. Pozzolana can be used for various types of construction and it improves the technical properties of cement. The pozzolana has a potential cost savings on the importation of cement by $30 million annually. Further improvement of the cement has been made (Pozzo-Mix), the improved cement can be used wholly without any combination with high quality results. The Pozzolana is especially suited for waterlogged areas.

Soil Improvement

CSIR-Soil Research Institutes (CSIR-SRI) has come out with crop specific fertilizer dosages for yield maximizaion. The institute has successfully applied the Quantitative Evaluation of the Fertility of Tropical Soils (QUEFTS) model to estimate site-specific marketable yields and the effect of fertilizer application on the yields of yam on benchmarks soils in the Interior Savanna Zone of Ghana. It has also advanced the use of Biochar technology for soil improvement. Furthermore, CSIR-SRI has developed options for the management of acid and other problem soil for improved agriculture productivity in Ghana.

In order to maximize agricultural productivity, online soil maps have been developed, these maps are to facilitate the determination of specific crops suitable for particular soils in the various agro-ecological zones of Ghana. Other yield maximization options developed include Soil-Water Conservation and Land Management strategies, conservation agriculture technology, Sawah technology for lowland rice, Soil fertility regeneration of depleted soils, integrated soil fertility management for crops and Soil pollution remediation.

An Agriculture research and development team of the CSIR-Water Research Institute has successfully developed an improved Akosombo Strain of the Nile Tilapia (Oreochromis niloticus). By selecting the fastest growing fish over eight successive generations, CSIR-WRI has developed the improved Akosombo strain which grows about 30% faster than those in the wild. Normally, tilapia takes eight months to reach maturity from the fingerling stage when they are purchased from hatcheries. However, under cage culture condition or system, the improved strain takes five months to reach a mean weight of 420 grams from an initial stocking weight of 15 grams. This means that fish farmers can produce more fish each year. Not only does the Akosombo Strain bring financial reward to the local farmer, but it provides the necessary dietary protein for millions of Ghanaians who feed on fresh fish.
