The exploitation or tapping of the rubber tree, Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg. is one of the most important cultural practices in determining useful life, yield and accounts for a major part of the total production costs in rubber farming. The objective of this work was to evaluate yield performance and economic aspects of rubber tree clones submitted to diverse tapping systems. The trial was placed in Guararapes city, São Paulo State, Brazil, in a randomized block design with split-plot in time. The plots consisted of the IAN 873, PR 261, RRI M 600 and RRI M 701 clones. The tapping systems consisted the subplots, where: ½S = tapping of half spiral cut; d/2, d/3, d/4, d/5 and d/7 = tapping every 2, 3, 4, 5 and 7 days,...
