My greenhouse maize plants are too thin. They have strips on the leaves.
The conditions are 14h day/10h night; 26-28°C day and 20-22°C night; 60% humidity; peat soil mixed with little sand.
I use Osmocote exact Standard 3-4 for fertilization. It is a granular and should work for 3- 4 month. It contains all important nutrients which dissolve gradually:
16% nitrogen (7,4% nitrate-N and 8,6% ammonium-N)
9% P2O5
12% K2O
2,5% MgO
0,02% B
0,056% Cu
0,45% Fe
0,06 Mn
0,025% Mo
0,02% Zn
The plants are at V4 stage now.
I think that the plants have a nutrition deficite. What is the best fertilizer for greenhouse maize? Du you have any suggestions for improvement?
Thanks!
You are probably correct. Several nutrient deficiencies result in similar striped corn symptoms (interveinal chlorosis) that can be very difficult to distinguish, including deficiencies in sulfur, zinc, manganese, and magnesium. Tissue analysis can be the best way to know which nutrient is deficient. The Hoagland's nutrient solution is one of the best fertilizers and the recipe can be found with an internet google search.
Hi Sina,
The Publication "Be Your Own Corn Doctor" The Fertiliser Institute, Washington DC, has a series of photographs showing the symptoms of major nutrient deficiencies. What growing medium are you using, there may be some nutrient binding by the medium. Yes Kris is correct a leaf tissue analysis would be your best next step.
Best wishes
Try testing your soil pH. The peat mix could be quite acidic and corn prefers closer to 6.5. Mixing in some lime can help.
