Abstract: To screen optimum combination of chemical fertilizers and rapeseed cake organic fertilizer, and improve the quality of‘Yunyan97’, a field experiment was conducted to investigate the effect of four combinations on its yield and quality. The results showed that the mix of 20% rapeseed cake organic fertilizer (360 kg/hm2) and 80% inorganic fertilizer (399 kg/hm2 base fertilizer+90 kg/hm2 topdressing) was optimal for the yield and quality, and markedly lower the soil- borne disease of ‘Yunyan97’ (P<0.05), the chemical composition coordination of tobacco was improved by 14.4% on average, and the smoking quality was improved by 5.90%. On average, and the yield, output value, average price per hectare, and the proportion of middle and superior tobacco leaves of the flue-cured tobacco were increased by 8.39%, 13.17%, 4.41% and 6.93%, respectively.
