The use of a mixture of fertilizers of plant and animal origin is important in the vegetable cultivation system, however, identifying the proportion of each fertilizer in the composition will lead to positive results for the crop that will be cultivated, in this sense, the objective was to study spontaneous species from the semi-arid region in proportions with goat manure in the production of coriander. The research was developed at the Rafael Fernandes Experimental Farm, belonging to the Federal Rural University of Semi-Arid (UFERSA). The experimental design used was a randomized complete block design with six treatments and four replicates. The treatments consisted of the proportions of hairy woodrose (Merremia aegyptia L.) in goat manure [0%; 20%; 40%; 60%; 80% and 100% of hairy woodrose on dry basis]. The coriander cultivar sown was Verdão. The characteristics evaluated were: plant height, number of stems, productivity, number of bunches and dry mass of coriander. The maximum agronomic efficiency of the proportion of hairy woodrose (Merremia aegyptia L.) in goat manure was 587.28 g m-2 of coriander with 5.79 units of sauces m-2 with the exclusive use of hairy woodrose (Merremia aegyptia L.) in the dry mass (100%). The efficiency of hairy woodrose in the evaluated characteristics is due to its concentration of chemical elements present in the dry matter (24.0 g kg-1 of nitrogen; 23.3 g kg-1 of potassium and carbon nitrogen ratio of 23/1).
