ABSTRACT The sunflower (Helianthus annuus L.) belongs to the Asteraceae family, adapts to different edaphoclimatic conditions, where, in this way, it is possible to grow in all regions of Brazil. In the Northeast of Brazil, an establishment of cultivation practices related to sunflower was sought, which makes it possible to exploit this crop under economic techniques, mainly because it is a plant that has a great nutritional use. The use of organic fertilizer as cattle manure becomes a very interesting alternative, considering the ease of use and the relatively low use. The objective of this work was to evaluate the development of sunflower in different types of treatment with bovine manure to determine the best composition of the substrate. 120 seeded plastic bags were used, 10 repetitions of 3 seeds, selected in four movements: (T1) 100% soil (control), and the controls (T2, T3 and T4), which are characterized by the different proportions of bovine and soil manure, 25, 50 and 75% of bovine manure, respectively. For a height (cm) of the sunflower plants, no statistical difference was observed between the procedures. Controls using less bovine manure had smaller diameters. The number of leaves presented was higher in plants submitted to (T1), which shows an average of 13.9, differing from the other parameters that did not show any difference between them. The controls used in this work made it possible to observe that the best development of sunflower plants was the result of a material rich in organic materials and nutrients necessary for the plant.
