- ItemEconomic Efficiency of Sorghum Microfertilizing in Smallholder Farms in the North-Sudanian Zone of Burkina Faso(2018-04-04) A. Traoré; B. Ouattara; H. Sigué; François Lompo; Andre BationoThe mineral fertilizer microdosing (MD) technique was disseminated in the North-Sudanian zone of Burkina Faso for 3 years, using various extension tools. This study aimed to analyze the economic efficiency as well as farmers’ perception of the use of MD technique. Quantitative and qualitative data were collected from 60 demonstration plots conducted by innovative farmers and from 300 households, using an interview guide during the focus groups. The results of the demonstration trials showed that this innovation significantly increased (P˂0.05) sorghum productivity compared to farmer’s practice. It even tripled sorghum yields when combined with soil and water conservation (SWC) techniques, and the use of improved seed varieties. It also led to the efficient use of production capital with cost-benefit ratios ranging from 1.3 to 6.9 depending on the sorghum germplasm and its combined use with SWC techniques. Farmers acknowledged the positive effects of MD technique on their socio-economic well-being through higher incomes from sorghum production and improved food availability. These results challenged policy makers to trigger actions aiming at promoting large-scale adoption of MD technique for sustainable local development.
- ItemImproving Agronomic Efficiency of Mineral Fertilizers through Microdose on Sorghum in the Sub-arid Zone of Burkina Faso(2018-04-04) B. Ouattara; B. B. Somda; I. Sermé; A. Traoré; D. Peak; François Lompo; S. J. B. Taonda; Michel P. Sedogo; Andre BationoMaintaining and/or improving soil fertility under conditions of climatic deterioration remains one of the major challenges facing small-scale farmers of the sub-Saharan regions in ensuring their food production. To address this issue, trials combining mineral fertilizer microdosing, MD (2g NPK/seed hole), soil and water conservation (SWC) techniques (zaï associated or not with stone lines or grass strips) were conducted for three years with sorghum (local and improved varieties) on two sites in the north Sudanian zone of Burkina Faso. The main objective of the study was to analyze the effects of the different technology packages tested on sorghum yields and soil chemical characteristics. The results showed that the use of MD technique enabled to double sorghum grain yields. This effect was further enhanced when combined with SWC techniques (45%). The use of the improved sorghum variety increased grain yields by approximately 11%, 70% and 85% when combined with SWC, MD and SWC + MD techniques respectively. Regarding the impact of these technologies on soil fertility, plots developed with SWC techniques showed increases in total organic carbon, nitrogen and phosphorus contents as well as in available phosphorus between 30% and 80%.
