We can provide information on onion cultivar performance in the field and in storage in the tropics, based on a series of co-ordinated trials across many countries which ran from 1990 to 2000. The results are available on diskette on application to Currah Consultancy. Our experience of developing this 'information-trading' network using minimal financial inputs may be of interest as an example to other groups, and was recently written up as a conference paper.
We can draw upon a large collection of scientific and extension literature on onions in the tropics and subtropics. This, together with our long experience, provides a basis for advising our clients. We are particularly interested in helping students at the post-graduate level in tropical countries with specialised information for their onion projects - this work is normally done on a 'pro-bono' basis.
Lesley Currah was the co-editor of the textbook 'Allium Crop Science: Recent Advances', published by CABI in 2002. Earlier publications include the 'Onion Newsletter for the Tropics', edited for the Natural Resources Institute, U.K., from 1989 to 1997; a bulletin, 'Onions in Tropical Regions', co-authored with F.J. Proctor and published in 1990, and a storage manual written with NRI colleagues and published in 1997. Recently a review co-authored with Dr A. Rouamba and entitled 'Onions in West Africa: state of research and future prospects' was published in 'Tropical Science'. A full publications list is available on request. Specialised bibliographies on onion storage and on seed production are currently being compiled.
