ABSTRACT
Root analysis of grapevine ( Vitis vinifera L .) in a vertisol at Juazeiro-BA, Brazil (9º22'S 40º 26' W), was perfomed to verify the effect of the irrigation system used (microsprinkle and trickle) on root distribution. Trenchs parallel to the plant rows were dug to sample the roots by the monolite method. Microsprinkle irrigated plants showed greater dry matter and a better distribution up to 120cm of depth compared to trickle irrigated plants, which showed a higher root concentration near emitters. The microsprinkle irrigation system also gave a better horizontal distribution of grapevine roots when compared to trickle irrigation.
Key words:
Vitis vinifera; microsprinkle; trickle; vertisol
