Fodder production has increasingly become important among pastoral and agro-pastoral communities in Kenya. A number of pasture production technologies have been introduced to these communities not only to enhance availability of livestock …
This study investigated the effects of intercropping arrangements and fertiliser combinations on growth and yields of African nightshade (Solanum nigrum L.). The study was carried out at the Kenya Agricultural and Livestock Research Organi…
Exposure of rice (Oryza sativa) to cold stress has significant negative impacts on its development and yield. Prospects of increasing production by growing rice in highland areas of Uganda have not been fruitful due to cold stress. It is t…
Blackberry (Rubus L. sub-genus Rubus Watson) fruits grow wild in Kenya, though in some parts of the world they have been domesticated and are cultivated. There is potential for their adoption in Kenya, however this requires that informatio…
Rural households mostly utilise wild fruits and vegetables as a supplement to household nutritional needs during lean seasons. However, nutritional benefits derived from a given food are influenced by nutritional knowledge, attitude and pr…
Baobab (Adansonia digitata L.) leaves are important non-timber forest product (NTFP) in rural areas and increasingly in urban areas in Africa. However, the overharvesting of the leaves constitutes a threat for natural stands of baobab. Thi…
The main objective of this research was to investigate the effect of chemical fertilizer, organic fertilizer and a combination of the two on maize (Zea mays L.) yield in Sudan. Three levels of fertilizer: 86 kgN/ha, 4 tonnes chicken manure…
Performance evaluation of five treatments on soil chemical characteristics and yield of maize was carried out in Lower Gweru, Zimbabwe. The treatments were gypsum, mopane ash, green manure, combined gypsum and green manure (green manure + …
Potato (Solanum tuberosum) is an important food and cash crop for smallholder farmers, giving more food, more nutrition and more cash per unit of area and time. Adoption of the crop is therefore seen as a pathway to improved smallholder fa…
Potato, Solanum tuberosum L., is one of the most important staple crops in Kenya. It has high potential for production. However, production does not meet the growing demand. There is need to analyze socio-economic factors affecting the tec…
Cowpea (Vigna unguiculata L.Walp) is an important food security and cash crop among poor households especially in eastern and northern Uganda. However farmers have reported grain yields as low as 50 kg ha-1, far below the potential yield o…
Broomrape (Orobanche crenata) is a major constraint to faba bean (Vicia faba) production particularly in northern Ethiopia. Few resistant faba bean varieties are capable of reducing the level of damage from O. crenata infestation in faba b…
Cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) are the two most important viral diseases affecting cassava (Manihot esculenta) production in Uganda. The two diseases persist in the plant system causing yield losses an…
Bemisia tabaci is one of the most common whitefly species worldwide that have been identified to cause serious harm in various crops through direct damage and as a vector of viral diseases. In Uganda, cassava varieties used have succumbed …
Turcicum leaf blight, caused by Exserohilum turcicum (Pass) K.J. Leonard and E.G. Suggs (teleomorph: Setosphaeria turcica (Luttrell) Leonard and Suggs), formerly known as Helminthosporium turcicum, is a major foliar disease of both sorghum…
Maize (Zea mays) is a crucial crop in Africa serving as one of the chief carbohydrate sources used as food and feed. However, maize is deficient in essential amino acids, lysine and tryptophan. Protein malnutrition is a major challenge as …
Sesame (Sesamum indicum L.) is an important income security crop among smallholder farmers in Eastern and Northern Uganda. However, Sesame webworm (Antigastra catalaunalis Dup) causes high yield loses in Uganda. A few sesame genotypes resi…
Destructive rice diseases like bacterial leaf streak (Xanthomonas oryzae pv. oryzicola) have been reported to be on the increase. In 2014, researchers in Uganda spotted signs typical of bacterial leaf streak disease (BLS) in rice fields in…
Bacterial leaf streak disease (BLS) caused by Xanthomonas oryzae pv oryzicola is one of the emergent biotic constraints to rice production in Africa. The disease, which can cause yield loss of up to 60% on susceptible cultivars, was observ…
Maize ear rots caused by Aspergillus flavus, Fusarium graminearum and Stenocarpella maydis reduce the quality of maize through production of mycotoxins and carcinogenic compounds that are harmful to both humans and animals when consumed. T…
Fungal diseases have been seriously limiting faba bean production in northern Ethiopia with a serious impact on household food-security and soil fertility management. The study was initiated to evaluate the synergistic effect of host plant…
In Africa, maize yield losses of 50-100% have been reported to due termite attack. Previous studies have demonstrated efficacy of Metarhizium anisopliae for controlling termites, however there is limited information available on the applic…
In the last few decades, farmers have relied on synthetic pesticides to managed crop pests and diseases. This is because synthetic pesticides are easily available, have quick knock down effect, have varied modes of action and are reliable.…
Incorporation of biological pesticides in integrated pest management has lately been considered effective in production of safe food for human consumption, aesthetically valuable for the prime markets and increase in crop yields. Despite t…
Maize is an important income generating food crop in Tanzania. However, yields remain low due to several limiting factors including among others diseases caused by fungi and viruses. The threat caused by several biotic factors in the count…
