Abstract

A survey will be conducted in 80 Niagara Rosada vineyards in Jundiaí, São Miguel Arcanjo and Jales regions, state of São Paulo (Brazil), to evaluate nutrient status of plants during two crop cycles. Leaf and soil samples will be collected and analysed. Results will be correlated with fruit production in order to asses optimal concentrations of nutrients. DRIS norms will be estimated based on the data bank from field survey. (AU)
