• Phaseolus vulgaris L
• Sulfates and chelates Mn and Fe

Currently the need of applying micronutrients is not a priority of the bean, but in all cultures, which some time ago there was much concern about them. The following experiment was conducted in a greenhouse at the Federal University of Uberlandia - UFU - Uberlandia Umuarama Campos-MG, having as its objective to compare the efficiency of foliar fertilizer formulations sulfate and chelated. Were made in pots with 3 kg soil, we used three independent experiments in completely randomized design (CRD) in factorial scheme 5 x 2 (5 doses and 2 sources of micronutrients) at doses of 20, 40, 60 and 80 mg dm(-3) that was planted four seeds of the variety of beans Perola, and after 15 days after emergence (DAE), there was then thinned two plants per pot. The seeds were sown on 9 April 2010 and plants were cut when more than 50% was at stage R5 (emission of flower buds), which occurred around 45 after emergence. The results showed that the evaluated sources applied to soil did not give a significant difference, but looking at the leaf level, it is noted that the source of chelated micronutrients provided many more than the sulfated.
