It is interesting to note that:

CRI-Vern Gracen, CRI-AGRA SP09, CRI-AGRA SP13 and CRI-Kofi Annan, all improved high-yielding, non-sweet sweet potatoes varieties, were released in 2017. They have staple taste, higher storage root yield, that is 19 to 39t/ha, sugar content is 14.47- 18.12 per cent, early-maturing (four to five months), and higher tolerance to the sweet potato virus (SPVD), sweet potato weevils (Cylas sp.) and alcidodes. They are suitable for all five eco zones in Ghana. The varieties can be used for fufu, French fries chunk[1]fried, ampesi (boiled/steamed), crispy chips, for bread and pastries, yoghurt, baby foods and juice gluten-free noodles. They are also potential enzyme source for breweries and other industries.
WAAPP Piesa 1, Manga-moya, Maa-Lana, Naachem-Tiir and Nutsugah Piesa, all Frafra potato varieties, were released in 2017. Their ovoid tubers are up to eight centimetres in length. Besides, their raw tubers are exceptionally nutritious, resistant to diseases and pests. They mature from107 to 113 days. The varieties are applicable to Guinea Savanna, Sudan Savanna, Coastal Savanna and forest zones. They can be used for thick porridge, tuo-zaafi, amongst others.
Sweet potato: CSIR-SA[1]RI Nan variety was released in 2018. This variety is resistant to diseases and pests, climate-smart, orange fleshed, high dry matter: 26-29.5 per cent, drought-tolerant and yields 24t/ha. It is suitable for Guinea and Sudan Savanna agro-ecological zones of Ghana. It can be used for thick porridge, tuo-zaafi, etc.
Sweet potato: CSIR-SARI Diedi variety was released in 2018. It is purple fleshed, tolerant to SPVD, yields 14t/ha and drought-tolerant. Applicable to Guinea and Sudan Savanna agro-ecological zones of Ghana. It can be used for ampesi.
Sweet potato: CSIR-SARI Nyumengre variety was released in 2018. It is white fleshed, resistant to diseases and pests, drought-tolerant and yields 16t/Ha. The variety is suitable for Guinea and Sudan Savanna agro-ecological zones of Ghana. It can be used for ampesi.
Sweet potato: Micro-propagation protocol for the mass generation of planting material of sweet potato (Ipomoea batatas) variety. The protocol supports the production of planting material to address the inadequate supply of sweet potato vines and storage roots. The procedure eliminates disease-causing organisms, giving the resulting plant[1]lets more vigorous growth and increased yield. Use of the protocol/method generates pathogen-free material which prevents the transfer of diseases and pests from one point to the other and allows easy international exchange of sweet potato germplasm. The protocol can be a foundation for downstream research applications including genetic transformation activities. The variety is applicable to Guinea Sudan Savanna agro-ecological zones of Ghana. Advantages: Mass production of true-to-type disease-free planting material for existing and newly released varieties. Additionally, it enhances rapid international germplasm exchange (limited quarantine requirements)
Munikpa groundnut variety was released in 2005. It matures in 90 days, yields 2.0 t/ha, kernels are of very large size, very high oil content (51.8 per cent) and moderately resistant to early and late leaf spot. Munikpa is suitable for Guinea Savanna ecology. Besides, it is suitable for oil production and confectionary products
Kpanielli groundnut variety was released in 2005. It matures in 120 days, yields 2.4 t/ha, kernels are of very large size, very high oil content (51.8 per cent), suitable for commercial production and resistant to early and late leaf spot. Kpanielli is applicable to Guinea Savanna ecology. It can be used for confectionary trade, has better resistance to Cercospora disease, has good resistance to foliar diseases and it is dry season feed for livestock.
Jusie Balin groundnut variety was released in 2005. It matures in 100 days, yield of 2.0 t/ha, oil content is 47 per cent. Jusie Balin is applicable to Guinea Savanna ecology. Has better resistance to Cercospora leaf spot disease. It is good field dormancy.
Edorkpo-mu nikpa groundnut variety was released in 2005. It matures in 90 days, yield of 2.0 t/ha, yields between eight to 12 bags in half an acre. It is suitable for all agro ecological zones of Ghana. Edorkpo-mu[1]nikpa is resistant to Cercospora leaf spot diseases, it is good field dormancy and can delay harvesting up to 10 days without germinating.
SARINUT 1 SARINUT 2 groundnut variety was released in 2019. It matures in 90 days, adaptable to climate change, high in protein and oil and yield between 8-12 bags/ half acre. It is applicable to Northern agro ecological zones of Ghana. Has a higher oil content of 51 per cent, resistant to Cercospora leaf spot diseases and can delay harvesting up to 14 days without germinating.
Bawutawuta cowpea variety was released in 2008. It is resistant to striga, medium-to-late maturing, has high biomass, yields 3.0 t/ha, has erect plant stature with few runners and small leaves and matures in 69-75 days. Bawutawuta is suitable for Guinea and Sudan Savannah zones. It has resistance to striga and resistant to most insects and diseases.
Songotra cowpea variety was released in 2008. It has erect plant stature with no vines and small leaves, matures in 62-65 days, majority of the pods are slightly above the canopy, seed shape is fairly round, the seed coat colour is creamy white and has potential yield of 2.0 t/ha. Songotra is applicable toSahel, Sudan and Savanna zones. It is highly resistant to striga. Besides, it is moderately resistant to most insects and diseases.
Padi-tuya cowpea variety was released in 2008. It has erect plant stature with few vines and large thick leaves, matures in 64-67 days, seed shape is round to kidney shape and yield potential is 2.4 t/ha. Padi-tuya is suitable for Sahel, Sudan, Guinea Savanna zones and humid areas. It has short cooking time. Besides, it is moderately resistant to insects, diseases and striga. The per cent harvest in total yield (determinacy) is moderate (about 72 per cent).
Zaayura Pali, Diffeele, Soo-Sima, Wang Kae and Kirk[1]house benga-1 cowpea varieties were released in 2016. They are resistant to cowpea aphid and striga. The varieties are adaptable over northern Ghana. They are good source of iron.

Can Ghana feed its people well? Building a nutrition-sensitive food system

Published

When we talk about nutrition in Ghana, the conversation often focuses on individual choices: eat more vegetables, reduce sugar and salt, drink more water and exercise regularly.

These messages are important, but they tell only part of the story. Good nutrition is not just a personal responsibility; it is also a food-system issue.

What Ghanaians eat is influenced by what farmers produce, what food costs, how it is processed and marketed, what is served in schools, and what information consumers receive.

Ghana has the agricultural capacity to produce a wide variety of nutritious foods, including vegetables, fruits, legumes, fish, eggs, roots and tubers. Yet production alone is not enough. Poor storage, transportation challenges and weak market access mean that an estimated 30 per cent of food in Ghana can spoil before reaching consumers or retailers, according to a 2025 study by the International Growth Centre. The losses are particularly significant for fruits and vegetables, reducing both farmers’ incomes and the availability of nutritious foods. This is where policy becomes important.

Agricultural policies should consider not only how much food Ghana produces, but also whether that food contributes to healthy diets. Greater support for diverse crops, local vegetables, fruits and legumes could strengthen both agriculture and nutrition.

The food-processing industry has a role as well. Processing can reduce food waste, improve convenience and create new markets for local produce. But greater attention should be paid to the nutritional quality of processed foods, particularly those high in salt, added sugar and unhealthy fats.

Public education must also become more practical. Telling people to “eat healthy” is not enough when nutritious foods may be unaffordable or unavailable. Consumers need information, but they also need a food environment that makes healthier choices realistic.

Good nutrition begins on the farm, continues through the market and food industry, reaches the school and household, and ultimately ends on the plate.

What is needed is greater coordination.

A successful nutrition strategy should connect agricultural production with health objectives, school feeding with local agriculture, food processing with nutritional quality, and public education with the realities of household income and food prices.

The ultimate goal is not simply to produce more food.

It is to ensure that Ghanaians have reliable access to safe, affordable and nutritious food throughout their lives.
