The effect of 24-epibrassinolide and 24-epicastasterone was tested in two years old Coffea arabica L cultivar Catuaí Amarelo at its first yielding, in two experiments. Yield, percentage of beans with empty locus, percentage of peabeans and other parameters related to the size of the seeds were evaluated. Fruit setting was evaluated in one experiment only. It was concluded that the brassinosteroids did not affect the yield or the parameters related to the size of the seeds.
