Crop yield and water use in smallholder irrigated Agriculture: a case study of Nyanyadzi (Zimbabwe) and Matanya (Kenya) irrigation schemes
(University of Nairobi, 1994)
The performance of most smallholder irrigation schemes has been disappointingly low.
This study aims at establishing the causes of low crop yield in Nyanyadzi and Matanya
irrigation schemes and to identify possible ...
Anthelmintic resistance, epidemiology and contlrol of gastrointestinal nematodes of small ruminants in Nyandarua district of Kenya and in Denmark
(University of Nairobi, 1996)
Control of gastrointestinal nematodes in ruminants is most effectively achieved through
interventions based on the epidemiology of the parasites. Until recently, the epidemiology
of nematode infections in ruminants in ...
Effects of residue mulch rate and placement on infiltration, runoff and soil loss of a nitisol
(University of Nairobi, 1994)
The effects of residue mulch rate and placement on infiltration,
runoff and soil loss was stu~ied under natural rainfall on a 16%
slope of humic nitisol at Kabete, Nairobi, Kenya.
The study had five treatments which ...
A survey of the prevalence of dirofilaria immitis (heartworm) infection in dogs along the Kenya coast
(University of Nairobi, 1994)
Dirofilaria immitis (D. immitisi also known as heartworm is the causative
agent of dirofilariasis, a major condition in the dogs which is associated with
debility and deaths in severe cases. It is known to occur in dogs ...
Effects of chemical composition of plant residues on nitrogen release and crop uptake
(University of Nairobi, 1997)
To supplement high cost of inorganic fertilizers, smallholder farmers in the tropics
are likely to increase the use of plant residues as a suitable source of plant nutrients
especially nitrogen (N) and phosphorus (P). ...
Clinical and pathological observations in Kenyan donkeys experimentally infected with trypanosoma Congolense.
(1992-09)
The study was conducted to establish the type and severity of
Trypanasoma congolense infection in donkeys, particularly the clinical picture,
and to correlate this with the effects on draught power and the role these
animals ...
The relationship between management factors, antimicrobial sensitivity and prevalence of staphylococcal mastitis pathogens in a random sample of Prince Edward Island dairy herds
(University of Prince Edward Island, 1992)
This study, an investigation of coagulase positive (CPS) and coagulase negative (CNS)
staphylococcal mastitis in 44 randomly selected dairy herds in Prince Edward Island (PEl) had three
major objectives. These are:
1. ...
Antibiotic activity of some plant extracts on pseudomonas syringae pv. Phaseolicola and Xanthomonas Campestris pv. Phaseoli.
(1994)
Several plant extracts were screened for
antibacterial activity against Pseudomonas syringae pv.
phaseolicola and Xanthomonas campestris pv. phaseoli in
vitro. Extracts from Eucalyptus citriodora Hook,
Nothoscordum ...
Use of generation mean scaling for estimation of variance components in maize breeding
(1992)
Genetic studies were carried out to estimate the
variance components in maize using six crosses, A x F, A
X 64, A x 8, F X 64, F x 8 and 8 x 64. The four parental
inbred lines (A, F, 64 and 8), the F1
, F2 and ...
Studies on Pigeonpea Leaespot: Etiology and the Effect of Plant Age and Leaf Position on Susceptibility of Pigeonpea (Cajanus Cajan )to the Leafspot Pathogen (Mycovellosiella Cajani)
(University of Nairobi, 1991)
In recent years incidence of Mycovellosiella leafspot damage has increased considerably especially during the wetter seasons in the pigeonpea growing areas. Regular occurrence of the disease has been noted both in the ...
