Available technologies to replenish soil fertility in East Africa
(Springer, 2006)
Low inherent soil fertility in the highly weathered and leached soils largely accounts for low and unsustained crop yields in most African countries. But in particular, the major nutrients, nitrogen (N) and phosphorus (P), ...
Agronomic Performance of three most Popular Commercial Watermelon Cultivars in Kenya as Compared to one newly introduced cultivar and one local Landrace grown on Dystric Nitisols under Sub- Humid Tropical Conditions
(Asian Research Publishing Network (ARPN)., 2008-11)
Agronomic performance trial involving five cultivated watermelon accessions available in Kenya was conducted at Maseno University Research Fields for two seasons between year 2007 and 2008. The accessions included three ...
Analysis of Fish Fillet Drying Rates under Three Solar Energy Drying Systems
(2009-02-20)
A small Box type solar dryer with controllable air inlet was designed and tested. The dryer had a mild steel absorber plate and a polyvinyl chloride (pvc) transparent cover and could be adjusted to allow variation in airflow ...
A study of yield characteristics during mechanical oil extraction of preheated and ground soybeans
(2007)
Abstract: Soybeans were extracted for oil by compressing a ground sample at various operating pressures, pressing durations and product bulk temperatures. The oil yield from the various operations was measured and expressed ...
Effect of moisture content on the physical properties of three varieties of sorghum seeds
(Elsevier, 2006-08-31)
Three sorghum varieties (Kari-mtama, Serena and Seredo) were obtained from the Kenya Agricultural Research Institute and reconditioned to moisture contents ranging from 13.64% to 21.95% db. The reconditioned grain kernels ...
Evaluation of the effect of ripening on the sensory quality and properties of tamarillo (Cyphomandra betaceae) fruits
(Elsevier, 2007-03-31)
Tamarillo (Cyphomandra betaceae) fruits were sourced from a single farmer from the Central province of Kenya soon after harvesting. The fruits were then cleaned and sorted in order to remove all immature and damaged fruits. ...
A study of yield characteristics during mechanical oil extraction of preheated and ground soybeans
(2007)
Soybeans were extracted for oil by compressing a ground sample at various operating pressures, pressing durations and product bulk temperatures. The oil yield from the various operations was measured and expressed as a ...
The drying kinetics of kale (Brassica oleracea) in a convective hot air dryer
(Elsevier, 2005-12-31)
The effect of air temperature and sample thickness on the drying kinetics of kale was investigated using a convective air dryer at a fixed airflow rate of 1 m/s and drying air temperatures of 30, 40, 50 and 60 °C. The ...
Research trends in modeling, optimization and control of the drying operation
(2007)
Drying food is an extremely sensitive operation that requires the proper monitoring and control of the heating medium temperature as well as the length of time that the product is exposed to this temperature. Since the ...
Physical changes during coffee roasting in Rotary Conduction‐Type Heating Units
(Blackwell Publishing Ltd, 2003-08-23)
Coffee beans were roasted in a rotary conduction-type-heating unit under constant heating surface or product temperatures ranging from 200 to 240C or 170 to 210C, respectively. the roasting duration was varied from 0 to ...
