The potential verticillium chlamydosporium and pasteuria penetrans for the management of root-knot nematode on small holder tomato farms in Kenya
Karanja, D. K. et al. 
Root-knot nematode (Meloidogyne spp.)is a serious pest problem in smallholder tomato farms in Kenya. Awareness of the toxicity effects and increasing costs of chemical control for root-knot nematodes has led to demand for alternative nemede management strategies, including the use of potential biological control agenet. The use of Veticillium chlamydosporium and pasteuria penetrans, as biocont ...

The effect of weeding regimes and maize planting density on quality of maize forage and grain yields
Kivuva, B.M et al. [.2004]
The effects of weeding regimes and maize planting density on maize growth and yield were evaluated during the 2001/2 short rains in the Centre Highlands of Kenya. Weeding regimes were weed free (w1), weedy (w2), pre-emergence herbicides (w3)and land weeding twice (w4). Maize densities were 9 (D1) and 18 plants M-2 (D2). Maize was thinned and assessed as forage at tasseling. Thinnings dry matte ...

Effects of defoliation frequency and intensity on production of four burned and unburned bushed grassland communities in South Kenya
Too, K. D. 
Effects of defoliation frequency and intensity on production of burned plant communities were studied in Kenya on the National Range Research station, Kibiko in 1985-1983. Study sistes were located in ecological zone V which showed some some contrast in topography, soils and dominant grasses. Two replications of four plant communities, dominated by combinations of five grasses were included wi ...

Kibet, Philip Kiptorus 
A six-month study was conducted in southeastern Kenya to dtermine the influence of varying bush canopy cover on dietary selection and nutrition of mature esophageally fistulated heifers. Replicated moderately stocked paddocks (2.25 ha)each, were grazed one day 28-30 days from june to November, 1982. Treatment paddocks were designated light, modarate and heavy bush conditions with 12.8, 31.5 an ...

Grazing systems effects on inflitration rates and sediment production of a bushed grandland Buchuma, Kenya
Mbakaya, D. S. 
A drip-type rainfall simulator was used to assess effects of grazing systems and vegetation on infiltration rates and sediment production at Buchuma Range Research Station, Kenya. Four livestock grazing treatment were studied: high intensity low frequency, rotation, moderate continous and non-grazing. A combination to cattle and goats were utilized in each treatment. Two vegetation types and b ...

Effects of prescribed seasonal burning on a comretum-commiphora plant community in south central Kenya
Kinyamario, Jenesio Ikindu 
Studies of prescribed seasonal burning on a combretum-commiphora plant community were conducted in Kenya on the National Range Research Station, Kiboko, in 1980-81. Dry and early rainy season burns were applied in different months. Dry season burns were more effective in reducing woody plant canopy cover, height and increasing stem mortality for most species. Early season burns produced greate ...

Effects of burning on diet quality and associated production systems of cattle and goats in Acacia savannahs of Kenya
Mbui, Moses Kiruki 
A one-year study on the seasonal effects of burning on the dietary nutrition of cattle and goats was conducted at Kiboko from March 1982 to march 1983. Four esophageally fistulated heifers and two goats were utilized to collect diet samples from two adjacent burned and unburned paddocks. Pre-burn and post herbaceous plant species frequency and density were evaluated in both paddocks. Post-burn ...

An evaluation of the relationships between fecal nitrogen and digestibility, crude protein and dry matter intake of forages
Ngugi, Kinuthia Robinson 
Fresh liveoak leaves (Quercus spp)were mixed with fair quality alfalfa hay to form four rations containing o, 25, 50, and 75% livestock leaves on "as fed"weight basis. The rations were fed to four spanish goats in a 4x4 latin square sequence. Relationships betweeen fecel nitrogen and the dry matter intake, total notrogen intake, and dry matter digestibiliyt were evaluated. Daily feed intake fe ...
