A t谷cnica do diagn車stico nutricional, para fins de recomenda o de aduba o mais racional e econ mica na viticultura, carece de padr es metodol車gicos para as condi es regionais de cultivo da videira. Com o objetivo avaliar e ajustar os valores padr es, ou faixaslimites, de diagn車stico nutricional para videiras, com base em tr那s metodologias de diagnose foliar, para melhor detec o do estado nutricional dos vinhedos, foram averiguados 30 vinhedos comerciais da cultivar de uva de mesa It芍lia e de 33 vinhedos da cultivar Rubi, nomunic赤pio de Marialva, regi o Noroeste do Estado do Paran芍, empregando as metodologias de diagnose foliar da Calif車rnia, de Michigan e da 芍frica do Sul, na safra normal de 2002. Analisaram-se dados de produtividade e teores de macronutrientes e micronutrientes. Os ajustes nos padr es foram realizados pelo m谷todo do n赤vel cr赤tico, por meio do crit谷rio da distribui o normal reduzida (NCRIz). A metodologia da Calif車rnia n o se mostrou adequada para as condi es regionais. As outras duas metodologias podem ser utilizadaspara a diagnose nutricional das videiras do munic赤pio de Marialva com pequenos ajustes. The technique of nutritional diagnosis, for purposes of recommendation of more rational and economical fertilization in wine growing, lacks methodological patterns for the regional conditions of grapevine cultivation. With the objective of evaluating and adjusting the existing values or limit ranges of the grapevine nutritional diagnosis, with base in three diagnosis methodologies to foliate the nutritional state of 30 commercial vineyards of the variety of Italy table grape was evaluated and 33 vineyards of the Ruby variety, in the city of Marialva. Three methodologies were used: California, Michigan and South Africa foliar analyses, in the normal crop of 2002.Productivity data, and macro- and micronutrients were evaluated. The adjustments to the standards were made by the method of the critical level, through the approach of reduced normal distribution (NCRIz). The results showed that the California methodology did not prove adequate for the conditions of Marialva; the others, with some adjustments, can be used for the nutritional diagnosis of the vine of the grapevines of the municipal district of Marialva.
