Artichoke is an alternative of extra income for farmers, especially in the Serra Gaúcha region. However, there are few studies on this crop regarding organic fertilization. The objective of this project was to evaluate different organic sources of nutrients in the production and quality of this culture. The experiment was carried out in the town of Fagundes Varela - RS, from April 21, 2018 to November 10, 2018. The variety used was the 'Verde Redonda Melhorada'. The transplant was done in furrows, with a spacing of two meters between the rows and one meter between the plants. The plots consisted of three plants. The experimental design was a randomized block with four replications. The treatments consisted of chemical fertilization (control); cattle manure; chicken manure; sheep manure; swine manure; purchased organic compost; a mixture of animal manure. The amount of manure and fertilizer to be added was calculated according to the proportion of nutrients present in each source, aiming to meet the needs of nitrogen. The yield and quality data had no significant difference between treatments. In this way, producers can choose the source of nutrients available on their property to grow artichokes organically using the recommended dose.
