Effect of Livestock and Poultry Manures on Production of Flue-cured Tobacco

Livestock and poultry manures were applied largely in agricultural production. Field experiments were conducted to explore the effects of livestock and poultry manures on flue-cured tobacco production. The result showed that the manure application delayed the resettling stages of flue-cured tobacco, but did not influence the mature stages of lumbar or uppermost leaves. Plant was higher in the manure treatment than those in common tobacco fertilizer treatment. The manure treatment increased the number of effective leaves 1-2.7 leaves per plant. The effective leaves were more for the treatments with pig or cattle manure than those with chicken manure. However, it was not significant for the tobacco yields among the treatments. The output values of the treatments with pig manure no. 1 and no 2 were slightly, but not significantly, higher than with cake fertilizer or common fertilizer. No significant different on tobacco flavor was observed between livestock and poultry manures and cake fertilizer treatments.
