In Brazil, the studies on the golden linseed planting are scarce, especially when related to the cultural treatments, possibly because this is a short duration culture and still has little interest when compared to soy or corn. Several factors can affect the linseed production potential, and with regard to fertilization, it can be done by applying part of the fertilizer at sowing furrows, by throwing sowing or in the soil coverage. The objective was to evaluate the golden linseed response (Linum usitatissimum L.) to application way of potassium chloride (KCl), the main mineral commercial source of potassium fertilizer. A totally randomized design was arranged by cultivation lines, consisting of a planting system with 3 forms of potassium fertilizer (K) application. The first application (T1) took place at planting time, applying potassium in the furrow, covering with a thin layer of soil, dropping the seed and then covered with earth. In the second application (T2), potassium was applied between the planting lines, also at golden linseed planting time, while the third (T3) potassium application happened just 12 days after sowing, i.e., after the germination. The T1 showed better performance, followed by T2 and T3, indicating that the best place and moment to apply KCl is in the furrow during the cultivation.
