TITLE:

IMPACTS OF THE USE OF HERBICIDES ON THE CULTIVATION OF SAFFLOWER, CARTHAMUS TINCTORIUS L., AND ITS POTENTIAL INCLUSION IN FAMILY FARMING IN THE NORTHEAST OF BRAZIL

SUMMARY:
Safflower, Carthamustinctorius L., is an oilseed species from the Asteraceae family that is cultivated all over the world, has many uses in the industrial sector and is adapted to semi-arid conditions due to its tolerance to low rainfall and high temperatures. It is currently considered a plant with great potential for biodiesel production due to the high oil content of its seeds, with around 72% linoleic fatty acid in its composition. The species in question has not yet managed to develop attributes favorable to its survival when exposed to situations of competition with other species, such as weeds, the most limiting factor, which can lead to a loss of productivity of up to 88%. The chemical control method has proved effective in oilseed crops in Brazil, and is made possible through the use of herbicides. Safflower crops do not have any herbicides registered in Brazil, so there is a need to expand studies on the performance of this control method, highlighting its effects on the crop. One of the main objectives of this study was to evaluate the impacts caused by the use of 10 herbicides, widely used in Brazil, in a field experiment in the semi-arid northeast of Brazil, comparing the morphological characteristics of the species, which showed favorable results when subjected to these treatments. The social aspect of this project aims to introduce safflower to family farming, as it is a crop of great economic importance in various industrial sectors, as well as being a promising species for biodiesel production in Brazil, making it possible to generate employment and income for various farmers. The cultivation of safflower in semi-arid areas could contribute to the demand for vegetable oil in Brazil, and with this, the importance of investing in local farmers is clear. After applying a semi-structured questionnaire to family farmers in the Apodi/RN region, it was possible to identify positive results regarding the level of acceptance of the species as a new source of local income.
