Resumo: | This experiment aimed at evaluating macronutrient extraction by branches and fruits of fig plants (Ficus carica L.) Roxo of Valinhos, in increasing potassium levels fertilization conditions, during orchard establishment and formation. The experiment was carried out in soil of low exchangeable potassium levels, in the Fazenda Experimental Lageado's orchard, belonging to Faculdade de Ciências Agronômicas, Campus of Botucatu. The experimental design was randomized blocks with four replications and six treatments, with parcels subdivided in time. The treatments consisted of six potassium fertilization levels (0, 30, 60, 90, 120 and 150 g of K2O plant-1) applied to covering during two agricultural years. The evaluations were performed in winter pruning branches and fruit harvest during production time. Significant differences occurred for macronutrients extraction in the branches and fruits, exclusively as effect of dry mass higher production in the treatments with superior potassium levels, where the highest amounts had been exported by the fruits. Macronutrients extraction by fruits and branches was N > K > Ca > Mg > P > S, respectively. |

O trabalho foi realizado em solo com baixos teores de potássio trocável, em área do Pomar da Fazenda Experimental Lageado, da Faculdade de Ciências Agronômicas, Campus de Botucatu. O delineamento experimental foi em blocos casualizados com quatro repetições e seis tratamentos, dispostos em esquema de parcelas subdivididas no tempo. Os tratamentos constituíram-se de seis níveis de adubação potássica (0, 30, 60, 90, 120 e 150 g planta-1 de K2O) aplicados em cobertura durante dois anos agrícolas. As avaliações foram realizadas nos ramos das podas de inverno e nos frutos durante o período de produção. Ocorreram diferenças significativas para as exportações de macronutrientes nos ramos e frutos, sendo que estas se deram exclusivamente pelo efeito da maior produção de massa seca nos tratamentos com níveis superiores de potássio, onde as maiores quantidades foram exportadas pelos frutos. A ordem de exportação de macronutrientes pelos frutos e ramos foi N > K > Ca > Mg > P > S, respectivamente.Universidade Estadual de Maringá2008-04-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/192110.4025/actasciagron.v27i1.1921Acta Scientiarum.
