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 ... -
Physiological and Agronomic Performance of Domesticated and Wild Cotton Germplasm from Selected Regions of Kenya
(2017-05)making cooking oil, soup and seed cake for animal feed industry among other uses. Performance of wild cotton germplasm in Kenya has not been well studied and therefore there is need for understanding the correlation of ... -
Planting Pits’ Effects on Soil Nutrients in a Sorghum and Pigeon Pea Rotation in Semi-arid Areas of Eastern Kenya
(Science Domain International, 2016-12)Planting pits are rain water harvesting structures that trap water and nutrients in surface runoff and rain water falling directly into the pits. Planting pits have been promoted for improving crop yields without considering ... -
Pollination Ecology of Desmodium Setigerum (Fabaceae) in Uganda; Do Big Bees Do It Better?
(2016-08)Explosive pollen release is documented in many plant families, including the Fabaceae. Desmodium setigerum E. Mey (Fabaceae) is a perennial herb with single trip explosive pollen release found in eastern Africa, and the ... -
