The Effect of Different Source of Iron on Nutritional Value of Greenhouse Tomato Fruit Grown in Peat Substrate

Summary

The Effect of Different Source of Iron on Nutritional Value of Greenhouse Tomato Fruit Grown in Peat Substrate The aim of the investigations conducted in 2005-2006 was to estimate the effect of different kind of iron chelates: Fe 8 Forte (EDTA), Top 13 (EDTA+DTPA) and Librel Fe DP7 (DTPA) and iron concentration 50, 75 and 100 mg Fe·dm -3 in growing medium on the yield and fruit quality of greenhouse tomato cv. 'Merkury F 1 '. Tomato plants were grown in peat substrate produced by Hartmann, which characterized natural low iron content. The experiment was set up in two factorial design in three replications. One plot covered 6 plants grown in spacing 0.6x0.5 m, plant population was 3.0 per 1 m 2. The best yield of greenhouse tomato cv. 'Merkury F 1 ' was recorded when Fe 8 Forte in 75 mg Fe·
