Abstract:: Taking United States of American F₁ hybrids of Tagetese recta as test materials, the effects of 0, 22.5, 45.0, 67.5, 90.0, 112.5 kg/hm² 6 potash levels of potassium fertilizer on biological characteristics and yield of Tagetese recta were studied. The results showed that by increasing amount of potash fertilizer, flowering early, height, stem diameter, strains of crown diameter, number of branches, dry weight per plant and chlorophyll lutein and yield were most, significant difference among treatments. In condition of this experiment, the reasonable amount of potash fertilizer to Tagetese recta in cold region was 22.5 kg/hm², which could make flower yield reach to the most 26.39 t/hm².
