In order to evaluate the effects of the combinations of vegetal ash and soil liming on growth and development in cowpea cultivation, an experiment will be conducted in a greenhouse at the Federal University of Mato Grosso, Rondonópolis Campus. The experimental design was a randomized block, arranged in a 6 x 2 factorial scheme, with four replications. The treatments will consist of six dosages of vegetable ash (0; 9; 18; 27; 36; and 45 g dm-3) submitted to two conditions (without liming and 60% liming) in 1,5 dm3 pots. height of the plant, number of leaves, chlorophyll index (SPAD), stem diameter and leaf area index, with intervals of 15 days after emergence (DAE), and at the end of the experiment, root dry mass, root volume, number of nodules and nodule dry mass. The results were submitted to analysis of variance by the F test and when significant, submitted to the Tukey test and regression analysis, both at 5% of probability using the statistical SISVAR software. The culture was positively influenced in the treatment with the use of vegetal ash as fertilizer, contributing to the growth and development of cowpea, obtaining better results in the dose intervals between 36 g dm-3 and 45 g dm-3.
