Novel sources of resistance to blast disease in finger millet
(2020)Finger millet (Eleusine coracana (L.) Gaertn. subsp. coracana) is the most important millet in eastern Africa and perhaps the oldest domesticated cereal grain in Africa. One of the major factors limiting finger millet ... -
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 ... -
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 ... -
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 ... -
Evaluation of crop arrangement and phosphorus rate on performance of maize-common bean intercropping in western Kenya
(Archives of Agriculture and Environmental Science, 2020)The effect of phosphorus (P) rate and crop arrangement on the performance of component crops in maize-bean intercropping systems was investigated at two sites; Malanga and Bugeng’i in western Kenya. A split plot design ... -
Response of soybean (Glycine max L.) to application of lime and phosphate fertilizer in an acid soil of western Kenya
(Research gate, 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 ... -
Effects of Vermicompost, Tithonia Green Manure and Urea on Quality of Swiss Chard (Beta Vulgaris L. Var. Cicla L.) in Kenya
(Canadian Center of Science and Education, 2021)Swiss chard (Beta vulgaris L. var. cicla) is a popular vegetable because it is nutritious, robust, easy to grow. It requires regular applications of nitrogen, which causes accumulation of oxalates and nitrates within 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 ... -
An agronomic and economic evaluation of integrated use of Calliandra callothyrsus and maize stover with urea in western Kenya
(2014)The agronomic effectiveness of integrating organic and inorganic nutrient sources has been demonstrated in Kenya but economic analysis is often lacking in such studies thus denying farmers the ... -
Response of the African nightshade to phosphate fertilizer application in Western Kenya
(Scholars Research Library, 2013)Although the African nightshade is increasingly becoming an important vegetable in Kenya, the consumer demand has not been met due to its low yields occasioned by lack of fertilizer use. The general belief is that traditional ... -
Effects of organic and inorganic materials on soil acidity and phosphorus availability in a soil incubation study
(Hindawi, 2012)We tested the effects of two organic materials (OMs) of varying chemical characteristics that is, farmyard manure (FYM) and Tithonia diversifolia (tithonia), when applied alone or in combination with three inorganic P ... -
Comparative effects of lime and organic materials on selected soil chemical properties and nutrient uptake by maize in an acid soil
(Scholars Research Library, 2011)The use of phosphate fertilizers and lime to mitigate P deficiencies and Al toxicities in Kenya has not been effective due to their high cost. Organic materials (OMs) are therefore being tested as cheaper alternatives but ... -
Effect of organic and inorganic phosphorus sources on maize yields in an acid soil in western Kenya
(Springer Netherlands, 2010-04-01)Springer Netherlands -
Effects of combining organic materials with inorganic phosphorus sources on maize yield and financial benefits in western Kenya
(Cambridge University Press., 2009-10-09)Due to escalating costs of imported fertilizers, there is renewed interest in the use of local nutrient resources in managing soil fertility in Kenya. We tested the effect of two organic materials, farmyard manure (FYM) and ... -
Effect of Sources of Phosphorus on Phosphorus Sorption in Cambisols and Ferralsols of Western Kenya
(2015-02-02)The influence of two organic materials (OMs); Tithonia and FYM and inorganic materials; triple superphosphate (TSP) and Minjingu phosphate rock (MPR) and Busumbu phosphate rock (BPR), when applied alone or in combination, ... -
Management of organic inputs in East Africa: A review of current knowledge and future challenges
(Scholars Research Library, 2011)Organic inputs in Africa are used mainly as sources of crop nutrients but most of the ones available on the farms such as crop residues, animal manures and composts are of low quality and insufficient quantity. Proper ... -
Response of Maize to Organic and Inorganic Sources of Nutrients in Acid Soils of Kenya
(2014-02-25)Maize yield in Kericho County, Kenya is limited by infertile acidic soils. The effect of inorganic sources of nutrients and amendments; triple superphosphate (TSP), calcium ammonium nitrate (CAN) and lime, were compared ... -
The effect of minjingu phosphate rock and triple superphosphate on soil phosphorus fractions and maize yield in Western Kenya
(Hindawi, 2014)We tested the effects of triple superphosphate (TSP) and Minjingu phosphate rock (MPR), when applied at phosphorus (P) rates of 50 or 250 kg P ha−1 in a factorial combination with urea or Tithonia diversifolia green manure ...
