Assessing residue effects of tobacco nicotine on the yields, nutrient concentrations and nicotine uptake of a subsequent maize crop
(Elsevier, 2022-03-01)
The residue effects of tobacco (Nicotiana tabacum L.) nicotine on the subsequent maize (Zea mays L.) crop
cultivated in soils differing in texture has rarely been studied for over a decade. The present study was conducted ...
Importance of bio-pesticides formulations in managing insect pests of sesame in Africa
(International Journal of Biosciences, 2022-02-27)
Sesame is an important oil seed crop worldwide. However, its production faces a number of challenges such as infestation by insect pests and diseases, use of unimproved seeds by farmers and drought. Among all, insect pest ...
Growth performance of the neglected crop Telfairia pedata across elevation and climate gradients in Northern Tanzania
(Elsevier B.V., 2022-02-07)
Herbaceous vines, including the neglected crop Telfairia pedata, play a key role in small-holder livelihoods of

Field Margin Plants Support Natural Enemies in Sub-Saharan Africa Smallholder Common Bean Farming Systems
(MDPI, 2022-03-28)
Flower-rich field margins provide habitats and food resources for natural enemies of pests
(NEs), but their potential, particularly in the tropics and on smallholder farms, is poorly understood.
We surveyed field margins ...

Can soilless farming feed urban East Africa? An assessment of the benefits and challenges of hydroponics in Uganda and Tanzania
(Elsevier, 2022-01)
East Africa has the potential to boost its urban food production through adoption of soilless farming techniques. The case study assessed the benefits and drawbacks allied with hydroponic vegetable farming among urban and ...
A simplified non-greenhouse hydroponic system for small-scale soilless urban vegetable farming
(Elsevier, 2022-10-09)
Majority of under-developed countries continue to face a challenge of food insecurity around urban areas resulting from factors such as; limited access to arable land. This study aimed at developing a simplified low-tech ...
Plant-Rich Field Margins Influence Natural Predators of Aphids More Than Intercropping in Common Bean
(MDPI, 2022-06-23)
Field margins support important ecosystem services including natural pest regulation. We
investigated the influence of field margins on the spatial and temporal distribution of natural enemies
(NEs) of bean pests in ...
Building sustainable societies through vertical soilless farming: A cost-effectiveness analysis on a small-scale non-greenhouse hydroponic system
(Elsevier, 2022-08)
The growing rate of population and urbanization among African cities versus the reducing arable land has roused curiosity in soilless farming as an urban farming method to enhance food security and urban sustainability. ...
