The Caribbean Agricultural Research and Development Institute (CARDI) has a new issue of CARDI Review. The new issue is the first of three issues which will appear in the next few months.
The first paper examines the issue of planting densities for hot pepper and arrives at the conclusion that yields could be increased by planting at higher intra-row densities.
The second paper showcases work which is being undertaken to mitigate against the effects of climate change, which already appears to be a factor that farmers have to contend with. Ten sweet potato cultivars and landraces were evaluated during the severe Trinidad dry season of 2014.
There were some clear conclusions as to the most drought tolerant: but results like this will, of course, need to be verified by further evaluations in different geographic environments. They also need to be repeated in other harsh climatic conditions before definite conclusions can be drawn. Nevertheless, much more is now known about the relative performance of the ten cultivars and landraces.
