Abstract Doubts remain about the adequate iron (Fe) concentration in nutrient solutions used for optimal plant growth, especially in gramineae like sugar cane (Saccharum officinarum L.). Therefore, the aim of this study was to evaluate the effect of Fe concentrations on growth, green color index and dry matter (DM) production in sugar cane cultivated in a nutrient solution. The hypothesis was that the nutrient solution must contain higher Fe concentration, which is used by the plant for optimum development. The study was conducted in a greenhouse with the variety IAC SP 93 3046, cultivated in pots (7.5 L) with aerated nutrient solution. The experimental design was completely randomized with five replicates and four treatments (0; 184; 368 and 551.4 μmol...

Abstract: Pot experiments were performed in a greenhouse to compare zinc (Zn) and iron (Fe) sources: 1) corn plants were grown in a Zn-deficient soil and received a Zn fertilization (0, 1.9, 3.8, and 7.7 mg kg-1; equivalent to 0, 5, 10, and 20 kg Zn ha-1) as ZnEDTA and ZnSO4; 2) sorghum plants were grown in a soil where iron chlorosis symptoms had been observed and received a Fe fertilization (0, 1.5, 3, and 6 mg kg-1; equivalent to 0, 3, 6, and 12 kg Fe ha-1) as Fe-EDDHA and FeSO4. Corn dry matter (DM), Zn concentration, and Zn uptake were higher with Zn-EDTA as compared to ZnSO4. In the sorghum experiment the highest DM production was obtained with Fe-EDDHA, which increased Fe concentration and uptake in higher proportion as compared to FeSO4. However,...
