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 ...
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 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 cutting position of rose rootstock cultivars on rooting and its relationship with mineral nutrient content and endogenous carbohydrates
(Elsevier, 2017-11-18)
The stem cuttings for propagating rose rootstocks are usually obtained from the
shoots on the mother stock irrespective of the position. However, adventitious root formation
may be influenced by the cutting position. ...
Effect of organic and inorganic phosphorus sources on maize yields in an acid soil in western Kenya

Effects of Tithonia diversifolia, farmyard manure and urea, and phosphate fertiliser application methods on maize yields in western Kenya
(2015-04-21)
Maize production in western Kenya is often limited by deficiencies of nitrogen and phosphorus. We assessed the effectiveness of Tithonia diversifolia green manure (tithonia), farmyard manure (FYM) and urea as sources of ...
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 ...
Effects of lime and fertilizer on soil properties and maize yields in acid soils of Western Kenya
(Academic Journals, 2018-03-29)
Many soils in Western Kenya are acidic and deficient in nitrogen and phosphorus. Acidity hinders crop responses to fertilizers applied to remedy nutrient deficiencies. The common liming materials used to ameliorate acidity ...
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 ...
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, ...
