In the under-developed world, farmers plant the seed that comes to hand. Usually it's poor seed - too much doesn't germinate, or it's a mixture of strains, or it contains weeds, or it has been damaged by insects. Their labor in the field is less productive because they planted bad seed. In Brazil a team of U.S. agronomists is developing solutions to this problem, funded by the U.S. Foreign Aid Program under the Alliance for Progress
