Welcome to the AgShare.Today Resource Centre

The AgShare.Today Resource Centre brings together a collection of resources related to agriculture. These include open access scientific journals and best practice guides that can be used for background reading and to support research initiatives. The AgShare Featured Resource showcases a new document each month that the AgShare team recommends to all members.

Oxidative stress responses during cassava post-harvest physiological deterioration

Post-harvest deterioration of cassava occurs rapidly and renders the crop unpalatable and unmarketable. This is attributable to oxidative burst, altered regulation of genes and accumulation of secondary metabolites. Interactions between these enzymes and compounds, together with other data, are used to develop a model of some the principal events involved in the deterioration process.

Promoting potato seed-tuber management for increased ware yields in Kenya, Uganda and the Republic of South Africa

This project evaluated technologies relating to bacterial wilt and seed-tuber production systems. Areas addressed were (1) biocontrol agents against bacterial wilt, including the approval of a biological control agent (BCA) for testing in Kenya, and (2) small-scale seed-tuber (SPSS) production system for trialling and the monitoring of pests in Uganda.

An epidemiological model incorporating vector population dynamics applied to African cassava mosaic virus disease

An epidemiological model of African cassava mosaic virus disease (ACMD) was developed in which the dynamics within a locality, of healthy and infected cassava, and of infective and non-infective whitefly vectors, were specified.
