Oriental tobacco

The practice in Katerini:

     

A few days after transplanting:      
40 kg/str (=400 kg/ha) of 4-14-30   
25 kg/str (=250 kg/ha) of 0-20-0   
35 kg/str (=35 kg/ha) of 0-0-50   

 

20 days after transplanting: 10 kg/str (=100 kg/ha) of Multi-K as side dressing

 

Side dressing:
     
1) Oriental Tobacco:      

N - 2-4 Kg/str   
P2O- 6-8 Kg/str   
K2O - 8-12 Kg/str   

 

2) Flue-cured (Virginia):      
N - 5-10 Kg/str   
P2O- 8-14 Kg/str   
K2O - 15-22 Kg/str   

 

3) Burley:      
N - 14-20 Kg/str   
P2O5 - 20-35 Kg/str   
K2O - 20-25 Kg/str
