Abstract

The objective of this study was to evaluate high dilutions of zinc and potassium sulphates, Sulphur, and buckwheat, in the mineral composition of onion bulbs in an organic system. The experiments were carried out at Epagri, Experimental Station of Ituporanga, Santa Catarina State, Brazil, from August to December, 2012 and 2013. The substances sulphates of zinc and potassium, Sulphur, and buckwheat were evaluated in separate experiments. The treatments in each experiment were foliar sprays to 0.5% of the 6 CH (CH - Centesimal Hahnemannian dilution), 12 CH and 30 CH, as well as control without application. The nutrients in the onion bulbs in descending order were nitrogen, potassium, phosphorus, calcium, magnesium, iron, zinc, manganese and copper. The high dilutions of zinc and potassium sulphates, Sulphur, and buckwheat do not differ between treatments for the composition of nutrients in onion bulbs.
