ABSTRACT Nitrogen is a major soil nutrient for the growth and development of crops. Nitrogen deficiency in-between pre-nodulation and nodulation in soya bean is critical to enhancing its growth and yield. Decision Support Systems for Agro-technology Transfer (DSSAT) model like CROPGRO-soya bean could be a useful tool for predicting starter nitrogen requirement in soya bean. However, information on starter nitrogen application to overcome Ndeficiency-induced-stress during early seedling growth...
ABSTRACT Non-Timber Forest Products (NTFPs) have been identified to contribute to community livelihoods. Such contributions are people as well as site specific and may be shortlived if continuous availability cannot be guaranteed. Information on the role of NTFPs in community livelihoods is crucial to their sustainable management; however, this role has not been properly documented in Taraba State. Therefore, contributions of selected NTFPs to community livelihoods in Taraba State were inves...

ABSTRACT Adoption of yield increasing technologies among farming households is one way of reducing poverty and food insecurity. In Nigeria, Root and Tuber Expansion Programme (RTEP) was implemented to develop improved technology of root and tuber crops. However, the impact of RTEP technology on poverty and food security has not been fully established. Therefore, the effect of RTEP technology on poverty and food security status of cassava-farming households in southwestern Nigeria was investi...
ABSTRACT Medicinal plants and plant-based medicines are widely used in traditional cultures all over Ghana and they are becoming increasingly popular in modern society as natural alternatives to synthetic chemicals.

ABSTRACT Studies on aspects of the biology of the Nile tilapia (Oreochromis niloticus L.) were undertaken in a man-made lake, the Weija reservoir in Ghana from September 2007 to August 2008. A total of 657 specimens of O. niloticus from commercial landings were examined of which 357 were males and 300 were females (sex ratio of 1: 0.84; P < 0.05). GSI was low in December 2007 and August 2008 and highest in March and May 2008. Fluctuations in the GSI, suggested that O. niloticus spawned thro...
