Although safflower has a great ability to adapt to different climatic conditions and the availability of nutrients for its development, the species in question has not yet managed to develop attributes favorable to its survival when exposed to situations of competition with other species, as is the case with weeds that appear throughout its development and because it is a slow-growing species with a longer cycle, competition becomes a more limiting factor, and there may be a loss of productivity of up to 88% (KRENCHINSKI; et al., 2018). The chemical control method is made possible through the use of herbicides, which kill or eliminate the epigeous phytomass of weeds. Safflower cultivation does not have any herbicides registered in Brazil, and there are few known products that are selective to the crop, there are also few studies on the use of herbicides to control weeds in the safflower crop, highlighting the need for more studies on the performance of the chemical control method through the use of herbicides for greater use of the crop in question.
Family farming has been gaining strength in the context of the revaluation of rurality and the recognition of the role of local economies. According to LIMA (2019), in Brazil, family farming is responsible for producing around 70% of the food consumed by the country's population, such as beans, rice, flour, corn and others. The cultivation of safflower in semi-arid areas could contribute to the demand for vegetable oil in Brazil, so it is clearly important to invest in local farmers. This project seeks to promote the inclusion of safflower in family farming, as it is a crop of great economic importance in various industrial sectors, as well as being a promising species to produce biodiesel in Brazil, making it possible to generate employment and income for various farmers.
