Effect of P-K fertilizer with a low Cl content on the yield and quality of aromatic and sun-cured tobacco
1991
Nianzu, H. | Sun Jiwei.
The effect of a phosphate rock-sulfuric acid-potassium chloride-complex fertilizer with a low chloride content (PKLCl) on the yield and quality of aromatic and sun-cured tobacco was studied. In areas where the soil is deficient in Cl and/or the rainfall is sufficient to leach the chloride below the plants' root zone, an application of PKLCl, together with a N fertilizer substitute for NPK complex fertilizer (K from K2SO4), can be administered to the tobacco. The PKLCl was able to increase the yield and improve the quality of cured-leaf tobacco, while the Cl content in the cured-leaf was still below 2% for sun-cured tobacco and below 1% for aromatic tobacco.
