Nutrition status of greenhouse tomato grown in inert media. Pt. 2. Microelements
2003
Chohura, P. | Komosa, A.
The effect of inert media and fertilization levels on nutrition status of greenhouse tomato cv. Maeva F1 was investigated. Mean microelement content was: 118.5 mg Fe, 51.7 mg Zn, 269.0 mg Mn and 11.43 mg Cu per kg of dry mass of the index parts of tomato. No significant effect of rockwool, expanded clay and polyurethane foam on the microelement contents was found in the index parts of the greenhouse tomato, except for zinc whose content was significantly higher in the leaves of plants grown in rockwool and polyurethane foam than in expanded clay. Fertilization levels did not affect significantly the content of iron, managanese and copper in the index parts, except for zinc whose content lowered at higher fertilization level. High tolerance of the tomato plants to zinc and manganese was found at the content of 2.01 mg Zn and 1.78 mg Mn per cubic m of water or feeding solution
