Teores nutricionais em folhas e frutos de figueira, submetida a épocas de poda e irrigação

Abstract

Resumo AbstractThe present study aimed to evaluating the nutritional content in leaves and fruits of the fig tree 'Roxo de Valinhos', pruned at different periods corresponding to the months of July, August, September and October in the years of 2004 and 2005, with and without the use of irrigation, in the county of Botucatu, São Paulo State, Brazil. To achieve this objective, the adopted experimental design was in blocks with subdivided plots and 5 replications, in which plots corresponded to treatments with and without irrigation and subplots included prunings done in the above-mentioned four months. The levels of N, P, K, Ca, Mg, S, B, Cu, Mn and Zn in leaves and fruits were evaluated in the two crop cycles. The results indicated no significant differences among macro and micronutrient levels in the leaves subjected to treatments with and without irrigation in the cycle 2004/05, except for cupper which showed higher level with the treatment including irrigation (6 mg kg -1 ). In the fruits, there was no difference, except for Zn, which also showed the highest levels (28 mg kg -1 ) with irrigation. In the crop cycle 2005/06, there
