Recent advances towards understanding and managing Kenyan acid soils for improved crop production
(African Journal of Agricultural Reseach, 2014-06-18)
This review focused on the efforts made to understand and manage Kenyan acid soils by use of inorganic, organic materials (OMs) and crop germplasms tolerant to soil aluminium (Al) toxicity and/or low soil available phosphorus ...
Genetic diversity of symbiotic bacteria nodulating common bean (Phaseolus vulgaris) in western Kenya
(Public Library of Science, 2018-11-15)
Biological nitrogen fixation (BNF) in legumes plays a critical role in improving soil fertility. Despite this vital role, there is limited information on the genetic diversity and BNF of bacteria nodulating common bean ...
Recent advances in the use of Tithonia diversifolia green manure for soil fertility management in Africa: A review
(Agricultural Research Communication Centre, 2020)
Tithonia biomass transfer was presented as a technology that would replenish infertile soils, enhance food security and eradicate
poverty in Africa in the 1990s. Since then, a huge volume of research has been conducted ...
Comparison of effects of phosphorus sources on soil acidity, available phosphorus and maize yields at two sites in western Kenya
(Taylor & Francis, 2013-03-01)
The effects of farmyard manure (FYM), Tithonia diversifolia (tithonia) and urea when applied alone or in combination with Minjingu phosphate rock (MPR), Busumbu phosphate rock (BPR) or triple superphosphate (TSP) on soil ...
Influence of plant density and nitrogen application on growth and quality of sweet pepper (capsicum annuum) in Uasin Gishu county
(Research Gate, 2020)
Sweet pepper an important export in Uasin Gishu had been facing a problem of rejection at the
international market due to failure to meet the specified quality standards. The field experiment was
conducted during the ...
Response of soybean (Glycine max L.) to application of lime and phosphate fertilizer in an acid soil of western Kenya
(Archives of Agriculture and Environmental Science, 2020)
The effect of combining lime and phosphate fertilizer on the performance of soybean (Glycine max L.) was investigated in a pot experiment consisting of nine treatments of three rates of lime (0, 4 and 8 t ha−1) in a factorial ...
Depletion of phosphate rock reserves and world food crisis: Reality or hoax?
(African Journal of Agricultural Research, 2020)
Phosphate rock (PR) deposits are the major source of phosphate (P) fertilizers for soil fertility
replenishment. The demand for P fertilizers in the year 2014 was 42,706,000 tons and was expected to
reach 46,648,000 tons ...
Effect of nitrogen sources on the yield of common bean (Phaseolus vulgaris) in western Kenya
(2018)
Depletion of soil nutrients due to continuous cultivation without adequate external fertilization is one of the challenges facing many smallholder farmers in western Kenya. This study was conducted to assess the effects ...
Influence of Lime and Phosphorus Application Rates on Growth of Maize in an Acid Soil
(HINDAWI, 2017)
The interactive effects of lime and phosphorus on maize growth in an acid soil were
investigated in a greenhouse experiment. A completely randomized design with 12
treatments consisting of four lime levels, 0, 2, 10, ...
