Assessing the speed of improved postharvest technology adoption in Tanzania: The role of social learning and agricultural extension services
(2024-03-12)The Purdue Improved Crop Storage (PICS) bag is often associated with preventing grain damage from insect infestation, reducing aflatoxin accumulation in stored grain, and avoiding exposure to hazardous storage chemicals. However, limited knowledge is available on the information channels driving the adoption of the technology. Using data from 429 households, this study examines the impacts of social learning and extension services on the speed of adoption of PICS bags in Tanzania. We utilized the ... -
Approaches and progress in breeding drought-tolerant maize hybrids for tropical lowlands in west and central Africa
(2024)Drought represents a significant production challenge to maize farmers in West and Central Africa, causing substantial economic losses. Breeders at the International Institute of Tropical Agriculture have therefore been developing drought-tolerant maize varieties to attain high grain yields in rainfed maize production zones. The present review provides a historical overview of the approaches used and progress made in developing drought-tolerant hybrids over the years. Breeders made a shift from a ... -
Cut, root, and grow: simplifying cassava propagation to scale
(2024-02-06)Cassava (Manihot esculenta Crantz) is an essential crop with increasing importance for food supply and as raw material for industrial processing. The crop is vegetatively propagated through stem cuttings taken at the end of the growing cycle and its low multiplication rate and the high cost of stem transportation are detrimental to the increasing demand for high-quality cassava planting materials. Rapid multiplication of vegetative propagules of crops comprises tissue culture (TC) and semi-autotroph ... -
Determinants and success of engagement in circular bioeconomy practices in African food systems
(2023-11-21)Ending hunger and ensuring sustainable food production and consumption patterns globally, as outlined in the United Nations 2030 agenda of sustainable development goals (SDGs), cannot be accomplished through a linear resource use model that has proven to be non-restorative and unsustainable. Therefore, a more sustainable model of resource use - the circular bioeconomy (CB) - has been proposed as an alternative to achieve circular, resilient, and sustainable food systems. This approach can help ... -
Changes in soil susceptibility to erosion under tillage and soil fertility management practices
(2024)The degree to which soil is susceptible to erosion is measured as soil erodibility which can be influenced by different land management options. This study evaluated the dynamics of soil erodibility to tillage and soil amendments in a maize field under five consecutive cropping cycles. Tillage treatments were no-till, minimum, conventional, and grassland fallow (control). The soil amendment treatments used were no amendment (control), NPK, poultry manure (PM), and ½ NPK+ ½ PM and these treatments ...
