[ Abstract ]
Agricultural extension services play an important role in development of agriculture and contribute to improving the welfare of farmers and other people living in rural areas. This study examines the impact of agricultural extension services on crop farmers’ productivity in Oyo state Nigeria. The study employed a multistage sampling technique to select the respondents who are thereby interviewed. The finding showed that the nearest neighbor matching algorithm results for all the extension services have impact on crop productivity in the study area. They also have lower value when compared with results obtained with radius matching estimator, and they were found significant except the case of training programme, where the ATT value for the nearest neighbor matching was higher than the radius matching. In addition to this, the balancing test revealed that there is no significant difference between the socioeconomic characteristics of both treatment and control respondents except in some variables with respect to each programme.

[ Abstract ]
The present study has as objective to examine the relation between health and economic development. Cameroon like the majority of the developing countries is not in margin of this situation especially when it is known that the health expenditure is almost financed by the households. The present study proposes a set of theoretical arguments and empirical evidences which reinforce the idea according to investment in human capital, through health is the main means of ensuring sustainable growth on one hand. The analysis is done at the level of Cameroon, over 34 years (1980 - 2013). A regression equation has been specified and then estimated through the methods of Ordinary least squares (OLS) and Generalised Method of Moments (GMM). The software used for the analysis is Eviews. The estimation results show that health has a positive impact on economic growth and significant at different threshold meanings. The study seems to suggest that a concerted effort should be made by policymakers to enhance health investment to accelerate economic growth which would reduce poverty.

[ Abstract ]
Selection of cowpea genotypes with leaves of good nutritional quality is an important research objective. The aim of this study was to evaluate the variability of three nutritional traits among fifteen cowpea lines and clarify their genetic control through an 8x8 half-diallel mating in order to create new varieties adapted to the high Guinea Savannah zone. Genotypes showed a high variability for protein (18.60 to 26.50%), dietary fiber (6.25 to 11.30%) and vitamin C (2.30 to 4.70 mg.g-1) contents in young expanded leaves. Improved line IT97K-573-1-1 appeared to be the most desirable genotype for the genetic improvement of nearly all the traits evaluated and therefore recommended for further use. Diallel analysis showed that additive and non-additive effects of genes were responsible for the genetic variation of these traits. Parents differed significantly for their general combination abilities (GCA) as well as hybrids for their specific combination abilities (SCA). These traits were controlled by partial dominance model with preponderance of non-additive genes for protein and dietary fiber contents. These parameters are strongly heritable (h² = 0.72 to 0.87). Dominant alleles are not harmoniously distributed among studied parents. Recessive genes have positive effects on all traits. These results could help breeders improve the nutrient quality of cowpea leaves by appropriate selection. Recurrent selection might be a useful breeding strategy.
