Abstract:

Adequate maternal nutrition prior to pregnancy is important for maternal health and favourable pregnancy outcomes. However, information on the dietary intakes of NonPregnant, Non-Lactating (NPNL) women in Ghana is lacking. A cross-sectional survey was undertaken to compare the dietary intakes of NPNL women of children aged 2 to 5 years who are either living in the Coastal (n=79) or Guinea Savannah (n=89) zones. Data were collected using various methods namely interviewer administered socio-demographic questionnaire, 24hr dietary recall records, with data collected on one working and one non-wo

Abstract:

The Ghana Meteorological Agency delineated Ghana’s geographical space into four agro-climatic zones namely the north, transition, forest and coastal zones. Since the demarcation in the 1960s, previous studies have rarely provided a more dis-aggregated agro-climatic zone map in tandem with contemporary climate change and variability. The continued use of this age-old classified zones is a disservice to the public. In this study, therefore, we evaluated the existing agro-climatic zone map of Ghana and reconstructed it to a more appropriate and dis-aggregated map that reflect current climate chan

Abstract:

Abstract The Guinea savannah zone of Nigeria is beset by increasing population and infrastructural development, thereby putting pressure on available land with rapidly declining fertility due to low organic matter content, soil erosion, high temperature and seasonal bush burning. Sesame is cultivated in this zone and the yield has remained very low, compared to yield in other parts of the world. This could be attributed to poor nutrient status and poor cultural practices used by peasant farmers. A field experiment was conducted at the Teaching and Research Farm, University of Ilorin, Nigeria,

Abstract:

The paper examines heat stress and its adverse effects as a hindrance to profitable poultry production in the tropics, with emphasis on the Northern Guinea Savannah zone of Nigeria. It elucidates the general negative effects of heat stress on physiological parameters of domestic chickens, and the specific impact of the stress on reproduction in the tropics. The deleterious effects are expressed in poor poultry well-being and reproductive performance. It is concluded that measures aimed at alleviating heat stress in domestic chickens must be adopted in order to enhance reproductive and, consequ

Abstract:

The effects of cumulative pan evaporation (CPE)-based irrigation scheduling on growth, yield, crop water use and crop water use efficiency of Irish potatoes (<em>Solannum tuberosum L.)</em> were studied. Irrigation scheduling was at CPE of 20 mm, 30 mm, 40 mm and irrigating at 7-days rotation (Control). Net depth of 50 mm was used. Pakistan, Nicola, SP and Dual were the four varieties of Irish potatoes used for the study. Irrigating at 20 mm resulted in early flowering, early germination, highest total yield at harvest, largest tuber sizes, heaviest tubers, and largest total number of tubers.

AbstractThere is limited documented scientific information on garden production systems managed in developing countries, partly because both researchers and research administrators have, until recently, ignored them as legitimate areas of study, and because such production systems have been regarded as informal production activities, managed outside conventional market and economic channels. Yet in a developing country such as Ghana, these production systems are potentially able to contribute substantially to the food security and health needs of households.

In the Guinea savannah zone of northern Ghana, the soils are reported to be declining for agricultural productivity. In these farming communities that depend on soybean production for their livelihoods, resource-poor farmers are not able to afford purchases of high cost inorganic phosphatic fertilizers to enhance the crop’s production. The need arises to identify efficient practices and strategies and research into alternative means of enhancing soybean production to improve food security.

Agronomic data were collected from trials conducted in 2020 and 2021 in outstations representative of the broad agroecologies of this region of Nigeria. The data were subjected to partial budget and marginal rate-ofreturn analyses. The results show varying potential of the cowpea varieties and spraying regimes across locations. Ife Bro

Abstract:

Soils in the Guinea Savanna agro-ecological zone of Ghana are depleted in major nutrients by continuous cropping and residue removal, resulting in low maize yields. While many studies have assessed the fertilizer requirements for maize, most did not account for the role of the soil type and maize genotype. A study was conducted on Plinthosol and Lixisol in the Tolon district of the Northern Region of Ghana to assess fertilizer and genotype effects on maize productivity. Two maize genotypes (i.e. Obatanpa -110 days to maturity) and (Dodzie - 75 days to maturity) were compared at three fertilize
