Effect of Optimum Ratio of Fertilizer Application on Yield and Quality of Tobacoo

Adopting the approach which the trial of application ratio and rate of N and P wasdevised in the same experiment, the optimum ratio of fertilizer application on tobacco and its maximum yield application rate was tried out. Result indicated that the ratio applied N, P and K by tobacco was an important factor which significantly affected the yield and quality of tobacco.Under the condition of the soil nutrient of the field trial the optimum application ratio of N, P and was 1:1.5:1, the influence of the ratio to the quality of tobacco was greater than application rate,but the influence of rate of fertilizer application to the quality was greater than to yield.
