The treatments were the following: every day irrigation; irrigation every other two days and irrigation with four days interval. The irrigation depth considered was 150 mm. The levels of available soil moisture considered influenced the number of plants with diameter of 3.0 mm, and, between 3.0 mm and 6.0 mm.
