DRIS: concepts and applications on nutritional diagnosis in fruit crops DRIS: conceitos e aplicações na diagnose nutricional em plantas frutíferas

By Francisco de Assis Alves Mourão Filho

Abstract

Nutrition and fertilization are important factors in determining fruit yield and fruit quality. There are several methods for plant nutritional status diagnosis, among them, two are relevant and named as Sufficiency Range Approach (SRA) and Diagnosis and Recommendation Integrated System (DRIS). This research reports the main concepts and applications of DRIS in nutritional diagnosis of fruit crops, comparing it with current nutritional diagnosis methods, indicating advantages and disadvantages, and possible limitations to be investigated.<br>A nutrição e a adubação são fatores determinantes na produtividade dos pomares e na qualidade de frutos. Dentre os diversos métodos de diagnose nutricional das plantas, destacam-se o critério de faixas de suficiência (CFS) e o sistema integrado de diagnose e recomendação (DRIS "Diagnosis and Recommendation Integrated System"). São relatados neste trabalho os principais conceitos e aplicações do método DRIS na diagnose nutricional em fruteiras, comparando-o com os sistemas atuais de diagnose nutricional, apontando vantagens e desvantagens, e possíveis limitações a serem investigadas
