Abstract: This test was carried out in Baoshan in order to provide theoretical references for the organic fertilizer applying properly. The effect of three kinds of organic fertilizers (oil cake, farm manure and straw stalk) and the different amount of application on growing, yield and output value of Hongda was researched. The results show that: The growth vigor was weakened with the amount of farm manure increased. Using straw stalk was not good in the prior period, but with the amount increasing, the growth vigor was enhanced after budding stage. Meanwhile the differences in growing vigor of different amount of oil cake were not significant. Compared in economical character, there were significant differences of yield between different treatments, but opposite to output value, average price and rate of first class of flue-cured tobacco. Yield and output value showed a trend of reducing with the amount of farm manure increasing, but average price and rate of first class of flue-cured tobacco increased. However as the increasing of amount of oil cake the economical characters increased at the beginning but reduced after. The effect of different amounts of straw stalk showed low yield and high average price. Compared to compound fertilizer output value of straw stalk was lower obviously. In a word, the economical characters were batter with using oil cake 150-300 kg/hm2 and using farm manure 7500-15000kg/hm2.
