Performance and Behaviour of the Leafhopper (Maiestas banda; Homoptera: Cicadellidae) Vector of the Napier Stunt Disease on Napier Grass (Pennisetum purpureum)

Abstract: Napier grass remains an important strategic grass species in east African mixed crop-livestock systems. However, production of several varieties of the grass remains constrained by phytoplasmic disease, Napier stunt disease (NSD), which is transmitted by the leafhopper, Maiestas banda. For smallholder farmers of western Kenya who rely on the grass for livestock feed and pest control in push-pull farming systems, effective control strategies of the disease and the vector remain elus...

Despite the opportunities, ther...

Susceptibility of common bean cultivars to storage fungal pathogens

In Menoua Division, common bean (Phaseolus vulgaris L.) is amongst the legumes which are greatly cultivated with farmers growing different cultivar types. Upon harvest, these cultivars are stored to be used as food over the storage period or for sale. Unfortunately, appropriate facilities for storing the cultivars after harvest are not available hence predisposing the grains to fungi infection. The knowledge of cultivars resistant to damage by storage fungi would therefore have a consider...

Mycotoxin contamination of stored maize in Kenya

In Kenya, maize is a staple food and is stored after harvest as a source of food and for sale. From the stored maize, the surplus from that meant for food is sold by some farmers to earn income. The quality of the maize in store depends on the storage facility. Poorly constructed and unmaintained structures may allow leakage of water and entry by rodents and insects which may mechanically damage the maize by nibbling and holing respectively, thus predisposing the grains to fungal infectio...

Evaluation Of Root- Knot Nematode Management Strategies Based On Nematode Distribution In Tomato (Solanum Lycopersicum) Fields In Mwea, Kirinyaga County, Kenya

Plant parasitic nematodes (PPN), particularly root-knot nematodes (RKN) are a serious pest problem in smallholder tomato farms in Kenya. For sustainable food production, effective management of plant parasitic nematodes is essential. Rootknot nematode management is primarily dependent on the application of chemical nematicides and the use of resistant varieties. However nematicide application is often done uniformly regardless of the relative nematode distribution in the farms, and yet it is ...

Host Resistance And Interaction Between Root Knot Nematodes And Fusarium Wilt Of Tomato

ABSTRACT Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops grown worldwide, owing to its nutritive value, income generation and diversified use. Tomato cultivation in the coastal region of Kenya is limited by root knot nematodes (Meloidogyne spp.) and Fusarium oxysporum. A survey was done in five farming counties of the Coastal region of Kenya. Meloidogyne spp. and F. oxysporum were isolated from diseased tomato plants and identified. Host resistance and interaction...

Review on effect of Nitrogen and Phosphorous application on seed yield and nutrient uptake of onion (Allium cepa L.)

Onion is a herbaceous biennial monocot cultivated as an annual crop. The number of flowers opening oneach day was influenced by hours of sunlight and concentration of phosphorous (P) and nitrogen (N). Nand P treatments tended to lower bolting percentages. The yield of onion seed per plant increased as thenitrogen in the nutrient solution increased where seed stalks were produced. The effect of early dressingsof N on crops grown under conditions when nights are becoming cooler is shown to allo...

Review on: Effect of seed storage period and storage environment on seed quality

Seed quality deterioration is inevitable process. Since seed is a vital input in agriculture which determines not justthe production but also the productivity, it is crucial to maintain the seed quality as well as seed vigor during the storage.
