Abstract
An experiment was conducted to study the effect of application rate of rape seed cake on yield and quality of flue-cured tobacco.The results show that output yield and value of flue-cured tobacco are highest at 25% N from rape seed cake and 75% N from compound fertilizer.However,output yield and value of flue-cured tobacco decrease when N application rate from rape seed cake is above 25% of total applied N.With the same application amount,output yield and value of fluecured tobacco in rotten rape seed cake treatment are higher than those in unprocessed rape seed cake.It is also observed that flue-cured tobacco leaf chemical quality balances well at 25% rotten rape seed cake,plus 75% compound fertilizer treatments.At 100% rape seed cake(rotten or unprocessed rape seed cake) or 100% chemical fertilizer treatment,flue-cured tobacco leaf chemical quality becomes very unbalanced.
