Resource Use Efficiency in Part-time Food Crop Production: The Stochastic Frontier Approach

In this paper, stochastic frontier production model was used to analyze the resource use efficiency of part-time food crop farmers in Idah, North Central Nigeria. The result shows that farm size, labour and planting materials are significant determinants of farm output in part-time food crop farming. Analysis of inefficiency factors reveal the significant inefficiency variables to include; level of education, household size and farming experience. The result also shows that over 72% of part-time farmers were above average in resource use efficiency; maximum efficiency is 0.98, while minimum efficiency is 0.36 with mean efficiency of 0.65. The study also revealed that rising age and household size contribute to resource use inefficiency in part-time food crop farming, while level of education and years of farming experience increased resource use efficiency among the sample farmers. Implications are that policies that would encourage relatively younger and educated persons and provide them easy access to improved seeds and fertilizers will go a long way in enhancing resource use efficiency in part-time food crop farming

Socio-Economic Determinants of Insecticides Usage in Cowpea Production in Kaduna State, Nigeria

This study investigates the socio-economic determinants of Insecticides use among cowpea farmers in Kaduna State, Nigeria. A multi-stage sampling technique was used to select 150 cowpea farmers who used insecticides in controlling pest in cowpea production in the study area. Information collected includes those of socio-economic characteristics of the famers and the quantity of insecticides they used. A regression model was used to estimate the relationship between farmers’ socio-economic characteristics and the insecticides use level. The study showed that family size, farm size level of education and years of farming experience were the major socio-economic determinants of insecticides use level among the cowpea farmers in the studied area. It was recommended that training and efforts to get farmers educated are intensified while strategies that will prevent migration of educated youths away from active areas of farming be put in place.Keywords: Cowpea, farmers, socio-economic, determinant, insecticidesJournal of Agriculture and Social Research (JASR) Vol. 11, No. 1, 201

Biodiversity, traditional medicine and public health: where do they meet?

Given the increased use of traditional medicines, possibilities that would ensure its successful integration into a public health framework should be explored. This paper discusses some of the links between biodiversity and traditional medicine, and addresses their implications to public health. We explore the importance of biodiversity and ecosystem services to global and human health, the risks which human impacts on ecosystems and biodiversity present to human health and welfare

Omics-based molecular techniques in oral pathology centred cancer: Prospect and challenges in Africa

: The completion of the human genome project and the accomplished milestones in the human proteome project; as well as the progress made so far in computational bioinformatics and “big data” processing have contributed immensely to individualized/personalized medicine in the developed world.At the dawn of precision medicine, various omics-based therapies and bioengineering can now be applied accurately for the diagnosis, prognosis, treatment, and risk stratifcation of cancer in a manner that was hitherto not thought possible. The widespread introduction of genomics and other omics-based approaches into the postgraduate training curriculum of diverse medical and dental specialties, including pathology has improved the profciency of practitioners in the use of novel molecular signatures in patient management. In addition, intricate details about disease disparity among diferent human populations are beginning to emerge. This would facilitate the use of tailor-made novel theranostic methods based on emerging molecular evidences

Influence of dietary non-phytate phosphorous levels and phytase supplementation on the performance and bone characteristics of broilers

Precise phosphorus nutrition is important for significant reductions in both P pollution and ration costs. The influence of different levels (%) of dietary nPP fed from 0 to 20 d (0.45, 0.40, 0.35, 0.30, 0.25, compared with feeding 0.20 nPP with and without 500 F.T.U. of phytase per kg of diet) and from 21 to 36 d of age (0.414, 0.364, 0.314, 0.264, 0.214, compared with 0.164 nPP with and without 500 F.T.U. of phytase per kg of diet) were evaluate using a total of 588 day-old commercial broiler chicks. Each treatment was replicated four times in a completely randomized design. Body weight (BW), daily gain (DG), feed intake (DFI), feed conversion ratio, plasma P level and bone characteristics were determined, and from these data the P equivalency of the phytase was estimated. Feeding diets containing less than 0.40% of nPP to birds between 0 and 20d resulted in inferior BW, DFI, plasma P level and bone characteristics compared with the control. However, optimum FCR and mortality was supported at lower levels of nPP (0.25%). Between 21 and 36 d, 0.364% was enough to optimise BW, DFI, and femur ash (%); whilst only 0.314% or greater was needed to support optimum DG, toe and tibia ash and only 0.214 to 0.264% was required to optimise shank, femur and tibia lengths; FCR and survivability. A broken line analysis also showed that the nPP (%) requirement ranged from 0.267 to 0.410 and 0.272 to 0.380% during 0 to 20 and 21 to 36 d, respectively. Phytase supplementation improved performance and bone criterion and its P equivalency, depending upon the response of interest and birds age, ranged from 0.00 to 0.110%. In conclusion, the results showed that the combination of a lower level of nPP and phytase may be used to increase dietary P utilization, without severe changes in performance and bone quality
