Effects of organic and mineral fertilizer inputs on maize yield and soil chemical properties in a maize cropping system in Meru South District, Kenya
(Springer, 2007-01)
Soil nutrient depletion as a result of
continuous cultivation of soils without adequate
addition of external inputs is a major challenge in
the highlands of Kenya. An experiment was set
up in Meru South District, Kenya ...
Soil Inorganic N and N Uptake by Maize Following Application of Legume Biomass, Tithonia, Manure and Mineral Fertilizer in Central Kenya
(Springer Netherlands, 2011-05)
In the smallholder farms of central Kenya soils suffer from nitrogen (N) deficiency due to
inability to replenish it through application of chemical fertilizers and/or manure. This study
evaluated the effect of some ...
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-10)
The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ...
Long-term effects of tillage, sub-soiling, and profile strata on properties of a Vitric Andosol in the Kenyan highlands
(2008)
Tillage alters the structure and composition of soil aggregates affecting infiltration rate (IR) and hydraulic conductivity (K). This study investigated the long-term effects of conventional, minimum, and no-tillage with ...
Coffee Drying in a Rotary Conduction-Type Heating Unit
(Blackwell Publishing Ltd, 2004-06-01)
Parchment coffee (Arabica) was dried from an initial moisture content of about 90% to 10% dry basis (db) in a recirculating rotary conduction type heating unit at controlled plenum temperatures of 100, 120 and 140C or ...
5 Infrared Drying
(CRC Press, 2010-07-26)
This chapter will present the mechanism, techniques, and advantages of infrared (IR) drying
for various food and agricultural products. The propagation of IR radiation from a source
(considered as any material at a ...
Alley cropping of maize with calliandra and leucaena in the subhumid highlands of Kenya Part 2. Biomass decomposition, N mineralization, and N uptake by maize
(Kluwer Academic Publishers, 1999-06)
A major challenge in developing agroforestry approaches that utilize tree-leaf biomass for provision of N to crops is to ensure synchrony between the N released from decomposing prunings and N demand by crops. A study was ...
The Potential of Organic and Inorganic Nutrient Sources in Sub-Saharan African Crop Farming Systems
(2012-02)
he Potential of Organic and Inorganic Nutrient Sources in Sub-Saharan African Crop Farming System
Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with inorganic nitrogen source in Central Kenya
(Kluwer Academic Publishers, 2004)
Decline in crop yields is a major problem facing smallholder farmers in Kenya and the entire Sub-Saharan region. This is attributed mainly to the mining of major nutrients due to continuous cropping without addition of ...
Local and landscape effects on bee functional guilds in pigeon pea crops in Kenya
(Springer, 2015-07)
Pollinators face many challenges within agricultural systems due to landscape changes and intensification which can affect resource availability that can impact pollination services. This paper examines pigeon pea pollination ...
