(Livestock Research for Rural Development, 2007-01-01)The efficacy of Tephrosia vogelli and Vernonia amygdalina leaf extracts as anthelmintic against Ascaridia galli was determined in-vitro and in-vivo.The extracts whose chemical constituents included rotenoids, sesquiterpene ... -
Traditional herbal preparations for indigenous poultry health management in Western Kenya
(Livestock Research for Rural Development, 2007-01-01)Conventional disease prevention methods are geared towards birds in confinement and not free range in an indigenous poultry production system. However, the existing indigenous technical knowledge inherited from past ... -
Effects of moisture loss on water potential components and tissue deterioration in carrots during Short-term storage
(American society for horticultural science, 1995-07-01)Studies were carried out to understand the effects of moisture loss on water potential and root deterioration in carrot (Daucus carota L. `Eagle') roots during short-term storage. The roots were stored at various temperatures ... -
Influence of preharvest water stress on postharvest weight loss of carrots (Daucus carota L.)
(American society for horticultural science, 1996-08-01)To understand the relationship between preharvest water stress and postharvest moisture loss, carrot cvs Eagle and Paramount were grown in muck soil in 6 1 pots (eight carrots per pot) in a greenhouse at the University of ... -
Potassium nutrition and shelf life of carrots (Daucus carota L.)
(American society for horticultural science, 1996-08-01)The effect of potassium (K) nutrition on the shelf life of carrots was studied using a hydroponics system involving rockwool slabs as support. Carrots were grown for 192 days under greenhouse conditions and supplied with ... -
Replacement of postharvest moisture loss by recharging and its effect on subsequent moisture loss during short-term storage of carrots (Daucus carota L.)
(American society for horticultural science, 1997-06-01)The replacement of postharvest moisture loss in carrots (cv. Caro-choice) by single and repeated recharging (i.e., rehydration in water) treatments, interaction between the duration of recharging and temperature during ... -
Effect of source, time and method of nitrogen application on growth and yield components of potato in Kenya
(2000)The effect of different sources of Nitrogen (N), time and method of application on growth and development of potato was investigated over two seasons using the cultivar Dutch Robjyn. The three sources of nitrogen (Calcium ... -
Assessment of rainwater retention in agricultural land and crop yield increase due to conservation tillage in Ewaso Ng’iro river basin, Kenya
(2006)Rainwater harvesting and management (RHM) systems are increasingly being recognized as one of the strategies of upgrading rainfed agriculture, especially by smallholder farmers in semi-arid environments. The need to increase ... -
Maize technology development and transfer
(International maize and wheat improvement center, 1998)More than three decades of systematic research have been directed toward maize technology development and transfer in Kenya. During that period, the maize research program of the Kenya Agricultural Research Institute ... -
Nitrogen requirements of potatoes.
(Orgz, 1989)Nitrogen fertilizer applications, for maximum fertilizer efficiencies and crop yields, should be based on the N required by the crop during its various growth stages. The objectives of this paper were to identify the N ... -
Effects of Nitrogen and Phosphorus fertiliser on growth and yield of ironweed (vernoniagalamesis)
(2003)Ironweed (Vernonia galamensis) is a promising new crop for industrial oil but information on its response to ferfiliser is scanty. A field experiment was conducted at the University of Nairobi Field Station farm during 2 ... -
