An attempt is made, from Australian field experience and the experimental record, to identify the climatic factors important in tropical pasture legume seed production. The main properties of the crops (primarilyStylosanthes spp., Macroptilium atropurpureum, Desmodium spp. and Glycine wightii) taken into account are: their usual adaptation to a cycle of summer vegetative and winter reproductive development; their common short-day flowering response; their need for a reliable dry season to stimulate vigorous reproduction, reduce disease risk, and facilitate harvesting; and their susceptibility to frost. The more important general requirements for suitability of a region for seed production are seen to be that: its annual average rainfall should be 800-2000 mm, with a predominantly summer wet season and no more than 400 mm falling outside the four wettest months; the average daily mean temperature of the coolest month should not fall below 17C; the ground frost risk should be low; and the latitude should be greater than 10. These values are used to map Australia, India, South and Central America, and Mexico in terms of their potential for seed production. |
