Management of Thrips in French Bean by Integrating Biological and Synthetic Pesticides in Conventional Spray Regimes

Thrips are major pest of snap bean that cause losses as high as 60% but the use of synthetic pesticides is restricted due to strict market regulations on maximum residue levels (MRLs). This study aimed at reducing the use of synthetic pesticides by integrating biological and botanical pesticides in the management of thrips in snap bean.

Management of bovine papillomatosis using an autogenous vaccine: A case study in Bukura Agricultural College, Western Kenya

Bovine Papillomatosis is a papillomavirus infection in cattle characterized by presence of warts of various sizes on the body of the affected animals. The virus usually affects the epithelial cells of the skin causing hyperproliferative lessions. Six types of papillomavirus are involved where BVP-3, BVP-4 and BVP-6 types cause true papillomas. Five cases of bovine papillomatosis were noted on Bukura Agricultural College farm where the diseases presented as dry cauliflower-like warts of varying sizes especially on the neck and shoulder regions.

Effect Of Farmyard Manure And Can On Yield And Quality Of Amaranthus Lividus In Lugari District, In Kenya

The main objective of the study was to evaluate the effect of Farm Yard Manure (FYM) and calcium ammonium nitrate (C.A.N) on vegetative growth, leaf yield, vitamins A and C as well as nitrates (anti-nutrients) content of vegetable amaranth in Lugari District. The effect of traditional method of cooking on the levels of these micronutrients and anti-nutrients was also evaluated. The incorporation of different concentrations of both FYM (10-20 tons/ha) and C.A.N (100-400 kg/ha) significantly improved the vegetative aspects and yield of the plant, during the rainy and dry seasons.

On the agroforestry system and in situ conservation of medicinal plant germplasm in transnzoia district, Kenya

In sub-Saharan Africa about 80% of the ever increasing population depends on ethnomedicine for their healthcare since modern medicine is mostly expensive or unavailable in rural homesteads. However, ethnomedicine is the one presently recognised as the most effective in treating new emerging diseases such as HIV/AIDS since no effective conventional medicine exists for their cure. Medicinal plants germplasm, which are the major sources of ethnomedicine form an important part of forests and riverine vegetation in Kenya.

Group ranch concept and practice in Kenya with special emphasis on Kajiado District.

Arid and semi-arid land (ASAL) in Kenya is not suited to arable farming and therefore extensive livestock production is the most appropriate agricultural activity. This has been and will continue to be the main economic activity and land use for a long time. The current high human population growth rates in ASAL will continue to cause serious shortages of land relative to demand and may reduce the capacity of the land to support large human and livestock populations. There is not enough land to be shared on an individual basis.

The role of communication in environmental management and conservation in Kenya: a case study of Nyanturago water catchment area in Kisii county

The purpose of this study was to find out the role of communication in environmental management and conservation at Nyanturago Water Catchment in Kisii County. This was because, out of 22 water springs at the wetland, four had dried up forcing the residents to travel long distances in search of the precious commodity. Eucalyptus trees have been criticized for consuming a lot of water draining the wetland and reducing water volume at Nyanturago River prompting its rehabilitation.

Enhancing Food Security Through Increased Potato Production In Kenya

Potato in Kenya is an important food and cash crop that plays a major role in food security and is only second to maize in terms of utilization. The crop has higher yields per unit area (40 tonnes per hectare) than most of the major food crops including maize and beans. Potato production has been increasing due to economic decline of competing cash crops such as maize, coffee and pyrethrum, and increasing demand from consumers and processors. Approximately 500,000 Kenyan smallholder potato farmers produce about 1 million tonnes from 100,000 ha of cultivated land area.

Integration of indigenous knowledge with information and communication technologies in coping with effects of climate change and variability on agriculture in Kajiado County, Kenya

Climate change threatens production’s stability and productivity. In many areas of the world where agricultural productivity is already low and the means of coping with adverse events are limited, climate change is expected to reduce productivity to even lower levels and make production more erratic. To help cope with the negative impacts of anthropogenic climate change, local people employ traditional Indigenous-Knowledge based practices.

CAVS hands over high yielding bean variety to Kenya Seed

The Kenya Sugar bean variety is an invention of the University of Nairobi (UoN) through the University of Nairobi’s Seed Company (UNISEED) in collaboration with the Seed Enterprise Management Institute (SEMIs) project. The project has embarked on breeder seed production of bean varieties bred by scientists at the University. The project seeks to address one of the greatest challenges faced by seed companies in Kenya and Africa which is accessing breeders or foundation seed for certified seed production. While handing over the seeds to Kenya Seed Company, Prof.

UoN Marks World Environmental Day

The ceremony which was held at the College of Agriculture and Veterinary Services (CAVS) Veterinary Farm- Kanyariri was done in partnership with Kenya Tea Development Agency (KTDA). The organization provided the 3000 tree seedlings to be planted, labour to dig the planting holes and to support the post planting care. Senior staff members from CAVS led guests, UoN and KTDA staff members in planting trees. Students’ organizations such as Runway Environmentalist, Upper Kabete Environmental Forum and Kabete Campus Student Organization represented the students. In attendance was Hon.
