The Effects of Cultivating Tobacco and Supplying Nitrogenous Fertilizers on Micronutrients Extractability in Loamy Sand and Sandy Soils
(MDPI, 2021-08-04)
This research was conducted to evaluate the trends of the extractable micronutrients boron
(B), copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) in soils differing in textures and collected
before tobacco cultivation, ...
Memoir and Farming Structures under Soil-Less Culture (Hydroponic Farming) and the Applicability for Africa: A Review
(ARCC JOURNALS, 2020-06-11)
Agriculture is the economic back-borne of majority of developing countries worldwide. The sector employs over 50% of the working population and contributes about 33% of the Gross Domestic Product (GDP) in majority of African ...
Characterization of land use influence on soil phosphate bioavailability in Usangu agro-ecosystem-Tanzania
(Elsevier B.V., 2021-12)
Phosphorus (P) is an important nutrient required for plant growth. Land use influences concentration and bioavailability of P in agricultural soils. About 198 soil samples (0-30 cm soil depth) were collected from three ...
Understanding farmer knowledge and site factors in relation to soil-borne pests and pathogens to support agroecological intensification of smallholder bean production systems
(Frontiers in Sustainable Food Systems, 2023-03-29)
Introduction: Pests and diseases limit common bean (Phaseolus vulgaris) production in intensifying smallholder farming systems of sub-Saharan Africa. Soil-borne pests and diseases (SPD) are particularly challenging for ...
Qualitative Cost-Benefit Analysis of Using Pesticidal Plants in Smallholder Crop Protection
(MDPI, 2021-10-15)
Assessing the potential drivers of farmers using pesticidal plants for crop protection is
essential for wider adoption. However, few studies have focused on collaborative assessments of the
underlying trade-offs when ...
Farmers’ Participatory Plant Selection of Lablab (Lablab purpureus (L.) Sweet) in Tanzania
(Frontiers in Plant Science, 2022-06-23)
Farmer-participatory breeding approach is an important component in the crop
improvement of lablab (Lablab purpureus (L.) Sweet). The study was carried out to
obtain the knowledge, practices and preferences of lablab ...
Building Resilient Crop Production Systems for Drought-Prone Areas—A Case for Bambara Groundnut (Vigna subterranea L. Verdc) and Groundnut (Arachis hypogaea L.)
(MDPI, 2023-01-28)
Drought is a major crop production constraint worldwide. Some legume crops are known for their ability to resist water deficit stress. This study evaluated the responses of bambara groundnut (Vigna subterranea (L.) Verdc) ...
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 ...
The diversity of aphid parasitoids in East Africa and implications for biological control
(Wiley Online Library, 2021-11-18)
BACKGROUND
Hymenopteran parasitoids provide key natural pest regulation services and are reared commercially as biological control agents. Therefore, understanding parasitoid community composition in natural populations ...
Biopesticide efficacy of four plant essential oils against papaya mealybug, Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae)
(Heliyon, 2023-03-01)
Worldwide, P. marginatus causes 75% of estimated economic loss in papaya farming, with an
increase in production costs. The extract of plant essential oils (PEO) has the potential to control
P. marginatus by degrading ...
