Genetic Variation Between Ecotypic Populations Of Chloris Roxbhurghiana Grass Detected Through Rapd Analysis.
(University of Nairobi, 2006)
Chloris roxburghiana is an important rangeland grass in Kenya. In some areas it has disappeared due to land degradation resulting from overgrazing and drought. Efforts to re-introduce the grass through re-seeding using ...
Farmers' perceptions on importance and constraints facing Napier grass production in Central Kenya
(University of Nairobi., 2006)
Farmers Focus Group Discussions (FFGDs) were done with groups of farmers in the intensive and semi-intensive farming systems in central Kenya. This was in the administrative districts of Nyeri (semi-intensive) and Kiambu ...
The abundance and efficacy of Rhizobium leguminosarum bv. viciae in cultivated soils of the eastern Canadian prairie
(2006-02)
For optimum production, the use of commercial rhizobial inoculant on pea (Pisum sativum L.) at seeding is necessary in the absence of compatible rhizobial strains or when rhizobial soil populations are low or symbiotically ...
Environmental hazards in African agriculture: factors influencing application of agrochemicals in Nakuru district, Kenya
(2007)
This paper uses data from a 2003 survey of farming households in Nakuru, Kenya. The objectives were: to establish the quantities of agrochemicals applied as compared to recommendations thus detecting under use or over dose ...
The abundance, efficacy, and diversity of Rhizobium leguminosarum bv. viciae populations in southern Manitoba soils
(2002)
Innoculation of field pea is necessary in the absence of compatible rhizobial strains, when the rhizobial populations are low or symbiotically ineffective. The prevalence and efficacy of Rhizobium leguminosarum bv. viciae ...
Recent developments in managing tuber blight of potato (Solanum tuberosum) caused by Phytophthora infestans
(2009)
Tuber blight, caused by Phytophthora infestans, occurs wherever potato (Solanum tuberosum) is cultivated and accounts for significant losses under field and storage conditions. After decades of research in late blight, ...
The value of radiographs obtained during forced traction under general anaesthesia in predicting flexibility in idiopathic scoliosis with Cobb angles exceeding 60 degree
(2008)
Our aim in this prospective radiological study was to determine whether the flexibility rate calculated from radiographs obtained during forced traction under general anaesthesia, was better than that of fulcrum-bending ...
Mechanical stresses in fast locomotion of buffalo (Syncews coffer) and elephant (Loxodonta africana)
(University of Nairobi, 2009-08-20)
Films of buffalo and elephant running, and detailed measurements on dissected legs, have been used to estimate the maximum stresses which occur in locomotion, in certain muscles, tendons and bones. These stresses are similar ...
Allometry of the legs of running birds
(University of Nairobi, 2009-08-20)
The principal bones, muscles and tendons of the legs have been measured in a selection of running birds, ranging in size from 0–1 kg quail to 40 kg ostrich. Maximum stride frequencies of the same species have been determined ...
Relationship Between Incidence of Late Blight Tuber Rot, Foliage Blight Control and the Effect of Weather and Soil Variables
(2008)
The relationship of late blight disease, tuber blight and the effects of weather and soil variables were determined at 2 distinct environments of New York and Kenya during 1999 to 2001. In well replicated field experiments ...
