The vegetal ash can become an alternative for fertilization of vegetables in the metropolitan region of Manaus, Amazonas. The objective of this work was to evaluate the effect of doses of vegetal ash on the growth and production of cress(Barbarea verna)and arugula(Eruca sativa). The vegetal ash presented high levels of alkalinity (pH 11.23), base saturation (100%) and cation exchange capacity (15.41 cmolcdm-3), with a high potassium content (4.950 mg dm-3). However,under the conditions inwhich the experiments were conducted,the tested doses of vegetal ash had no additional beneficial effects on the development of plants.
