CULTURAL ADVICE ON THE USE OF ZEOPROFIT HELLAS FERTILIZERS FOR THE CUTTING OF TOBACCO.
Smoke has a slightly acidic reaction (pH - 6). Increased nutrient requirements are in the stage of lengthening the shoot. Dung can be used because it releases nitrogen at a slow pace and improves structure, Nitrogen sufficiency helps to rigorously mature and improve tobacco quality as long as it is exhausted in the soil 60-70 days after transplantation.
Nitrogen perimeter in the soil not only delays maturation, but also increases the leaf size and decreases the dry matter in the leaves, thus degrading the quality of the tobacco.
Nitrogen deficiency in the early stages (60-70 days) results in the production tobacco with leaves small, yellowish yellow leaves with a low elasticity with an uneven surface, rich in cell walls that generally degrade quality.
Since the form of nitrogen affects the quality of the tobacco, 50-60% of the ammoniacal form should be given along with P and K and Mg in the basic and the remainder as nitrate 25-30 days after transplantation.
The other elements (P, K, Ca and Mg) play a very important role in plant nourishment, because they increase the resistance of the plant in excess, and because they decisively improve the quality of the tobacco.
Tobacco smoke should contain up to 1.5% N, which means N-fertilization up to 5 kg N / ha, 2-3% K (medium lubrication) and approximately 0.2% P
Cigar and pipe tobacco can contain up to 2-3% N (up to 10 kg N / ha) and 4-5% K for better combustion. Desirably, it is also high in P and Mg content. In general, tobacco is proposed as follows:
Types of tobacco:
a) 0-6 N, 4-14 P2O5, 36-40 K2O, 4-6 Mg
b) Virginia 0-8 N, 16-34 P2O5, 40 K2O, 4-8 Mg
c) 10-24 N, 20-36 P2O5, 40-45 K2O, 6-10 Mg
d) Katerinas (Shamps) 0-3,5N, 8-14 P2O5, 36-40 K2O, 4-6 Mg
The above nutrients are Kg / acre.
Because the smoke is sensitive to chlorine, chlorine fertilizers should be avoided.
Loss of B may also occur in tobacco. The desired leaf concentration B is 20 mg / kg dry matter.
PROPOSED DOSAGE:
100 kg / ha of zeolite for incorporation
12.5 Kg / 1000lt water zeolite powder
30 - 0 - 0 +4 MgO + 0.1 Fe + 0.3 B + 17% zeolite
5 - 10 - 20 +6 MgO + 0.1 Fe + 19% zeolite
28 - 8 - 8 +0.5 Zn + 13% zeolite
12 - 12 - 12 + 3 MgO + 0.1 Fe + 25% zeolite
