          Abstract

          O diagnóstico do estado nutricional de uma planta e/ou lavoura depende de valores de referência. Assim, objetivou-se com este trabalho estabelecer normas DRIS e realizar um diagnóstico nutricional das lavouras de café arábica na região Noroeste do estado do Rio de Janeiro. Para realizar o diagnóstico, foram amostradas 125 lavouras; e, para estabelecer as normas, foram selecionadas 25 lavouras de café com produtividade superior a 40sacas/ha. Quantificou-se o número de lavouras em que os índices DRIS apresentaram-se mais negativos e mais positivos onde os nutrientes Ca, B, Zn e K foram os que mais se apresentaram como limitantes e onde o Fe e o Mn foram os nutrientes que ocorreram com maior freqüência com índices mais positivos, ou seja, em excesso.

          Translated abstract

          Reference - 'DRIS' - standards are essential for evaluation of the nutritional status of coffee plantations, and such standards are not yet available for the State of Rio de Janeiro. In this work, 125 well-conducted plantations had their nutritional status evaluated through foliar analysis. The results obtained for those 25 plantations with productivity above 40 60kg-bags per hectare were used for developing the "DRIS" standards. The nutrients calcium, borum, zinc and potassium seem limiting for the productivity, while iron and magnesium were found in excessive amounts.
