In this study, effects of different iron sources and doses on
plant growth criteria in soybean (Glycine
max L.) seedlings were investigated. The experiment was conducted according
to factorial experimental design with three replications under controlled
conditions. Atakişi variety of soybean (Glycine
max L.) cultivar was used as a plant material. Three soybean seeds were
sown each plastic pot having 1.3 kg soil:sand mixed in 1:1 ratio. Three
different Fe sources (FeSO4.7H2O, Fe-EDDHA and nanoFe)
were applied to the pots with three different doses (0-15-30 mg Fe kg-1).
The experiment was ended after five weeks of seed sowing. Shoot length, shoot
fresh and dry weights, root length, root fresh and dry weights and number of
compound leaf in soybean seedlings were determined at the end of the
experiment. The highest shoot fresh and dry weights, root fresh and dry weights,
compound leaf number were determined in 15 mg kg-1 nano Fe
applications as 3.56 g, 0.83 g, 2.30 g, 0.33 g and 5, respectively. Increasing
the application dose of nano-Fe from 15 to 30 mg kg-1 caused to
decrease in fresh and dry weights in soybean seedlings. Generally, shoot growth
decreased and root length increased in soybean seedlings by increasing Fe
application doses. Seedling growth in soybean generally increased depend on the
Fe sources in the following order; FeSO4.7H2O <
Fe-EDDHA < nano-Fe.
