https://revistas.upr.edu/index.php/jaupr
The Journal of Agriculture of the University of Puerto Rico publishes a volume of articles and research notes twice a year. Much of the content has relevance to tropical agriculture as it is a product of the Agricultural Experiment Station of the University of Puerto Rico with information on agriculture in Puerto Rico and other parts of the Caribbean and Latin America. They no longer produce printed material, but each volume will have PDF download links to each research article. On the home page, you can select English or Spanish, though not all articles are available in both languages. The archives section contains volumes going all the way back to 1917!
