Abstract

The use of organo-mineral biofertilizers containing alga extracts is recent in Brazil. Thus, the objective of this study was to evaluate the effect of leaf application of Ascophyllum nodosum extract biofertilizer on growth and on the nutrient content of carrot. The experiment was carried out in the garden area at Parana Federal University, in the city of Pinhais, State of Parana, in 2009, in an organic system, using the cultivar Nantes. The treatments consisted in the application of organo-mineral biofertilizer containing alga extract in different seasons and at different concentrations. The applications increased shoot height, root diameter and number of leaves. Yield increased with the application of the biofertilizer, regardless of concentration and period of application. The nutritional content in shoots and roots were also changed due to the application, where a decrease on foliar contents of Cu and on the root contents of N, Ca, Mg, Cu and Zn was observed possibly due to the dilution effect as a result of the increased biomass.
