Título em português: Formato de cápsula e modo de instalação influenciando determinações do potencial mátrico por tensiômetros.  aThe objective of this work was to determine the measurement accuracy of the soil water matric potential by puncture tensiometers with either rounded or pointed porous cups, installed with or without "soil mud", and to compare the performance of these tensiometers with that of tensiometers equipped with mercury manometers. The experiment was conducted in a Ultisol, in a randomized complete block design, in a factorial arrangement with five replicates. Puncture tensiometers with rounded porous cups, installed with soil mud, present more elevated accuracy for ; determination in a wider measurement range, resembling tensiometers equipped with mercury manometers in drying soil.  aCápsula arredondada  aLama de solo  aPuncture tensiometers  aRounded porous cup  aSoil mud  aTensiômetros de punção1 aSILVA, A.
