Effect of puncture vs conventional tapping on the yield and girth of Hevea
1983
Soyza, A.G.A. de | Samaranayake, C.
Puncture tapping of trees 35 cm or more in girth has resulted in higher kg/area yields than conventional tapping of trees 45 cm or more girth, during 4 months of a 12 month period whilst yield in terms of grams per tree per month was always greater with conventional tapping. Puncture tapped trees have a higher girth increase than do conventionally tapped trees of the same initial girth although annual yields are lower
