Food policy 2013 v.41 pp. 39-52
ISSN:

Subject:
corn; farmers; fertilizer rates; mineral fertilizers; nitrogen; profitability; research planning; surveys; Kenya
Abstract:
... It is widely perceived that African farmers are under-utilizing inorganic fertilizer. However, very little long-term evidence from farmers’ fields, accounting for variations in agro-ecological conditions, has been assembled to back this claim or determine the conditions under which it is true. Using five waves of nationwide household survey data from Kenya covering 13years, we estimate the relativ ...

2. Fertilizer use in semi-arid areas of Kenya: analysis of smallholder farmers' adoption behavior under liberalized markets

Subject:
educational status; family size; farmers; farms; fertilizer rates; fertilizers; markets; regression analysis; semiarid zones; Kenya
Abstract:
... This paper analyzes the factors influencing farm level fertilizer adoption decisions under an era of liberalized markets in Kenya using a Tobit regression model. The level of education of the household head, experience using fertilizer, growing a cash crop, availability of fertilizer in rural retail outlets, availability in small packages, and land pressure positively influenced fertilizer use, wh ...

Oxisols; Ultisols; abiotic stress; acid soils; agroecological zones; crop production; farmers; fertilizer rates; harvest date; highlands; irrigation; irrigation water; nitrogen fertilizers; probability; regression analysis; rice; rice straw; silicon; soil properties; soil sampling; surveys; Benin; Ghana; Guinea; Kenya; Madagascar; Mozambique; Nigeria
Abstract:
... Rice is a specific silica-accumulator among higher plants. The Si in rice enhances resistance to biotic and abiotic stresses. The booming demand for rice in Sub-Saharan Africa (SSA) requires rapid increases in rice production, and hence more Si supply will be needed from soils, irrigation water, and external inputs. However, the current Si-nutrient status of rice plants and relevant factors has be ...

Subject:
beans; biomass; corn; cropping systems; farmers; fertilizer rates; field experimentation; grain yield; long term effects; phosphorus; profitability; rock phosphate; soil; soybeans; triple superphosphate; Kenya
Abstract:
... Crop production in sub-Sahara Africa is constrained by low soil phosphorus (P) content. A study was conducted in western Kenya to explore alternative P inputs and ways of optimizing their effectiveness and profitability. A field experiment established in 2007 studied the effects of Minjingu phosphate rock (MPR) and triple superphosphate (TSP) on maize, common beans and soybean yield. MPR and TSP w ...
