The objective of this research was to evaluate the effect of the application of different irrigation water volumes in cover and uncovered soils on growth and development of dwarft coconut (Cocos nucifera L.). The study was conducted in the Carirí region of Paraiba State ,135 km from the capital, João Pessoa, Brazil. The experimental area was 3840 m2, where the coconut was planted with a space between plants of 8.0 x 8.0 x 8.0 m. The study was initiated on March 2, 2005 and finished on May 30, 2006. The experimental design used was a factorial randomized block [(4 x 2) +1] with four irrigation water volumes and two soil covers as treatments and an additional plot as control, totalizing 36 plots. The results did not show any significant difference for plant height and stem diameter. Considering that the amount of water applied to the uncovered treatments was half of the water applied to the covered one, it was observed a great water economy on the soil covered with the plastic film.
