Faixas normais de nutrientes em cana-de-açúcar pelos métodos ChM, DRIS e CND e nível crítico pela distribuição normal reduzida

Abstract: Existem diversos métodos para a interpretação da diagnose foliar; o nível crítico ou as faixas de suficiência descritas na literatura são os mais utilizados. Porém, o uso de métodos de determinação de faixas normais de nutrientes que contemplam regiões específicas (localidades) aumenta a eficiência da interpretação. O objetivo deste trabalho foi determinar as faixas normais de nutrientes para a cultura da cana-de-açúcar, mediante a utilização dos métodos Chance Matemática (ChM), Sistema Integrado de Diagnose e… Show more

“…The range similarity of the DRIS and CND methods and reduction in the amplitude of adequate contents in relation to official norms were also observed by Camacho et al (2012), Kurihara et al (2013), Santos et al (2013a) and Partelli et al (2014). Lower amplitude in the adequate ranges is highly desirable, because it increases distinction between balanced and unbalanced crops.…”

“…This disagreement demonstrates the importance of having regionalized standard scores for leaf diagnosis, or generated for each growing condition (Serra et al, 2010;Gott et al, 2014). Similar conclusion regarding the importance of regionalization of optimum leaf nutrient levels for the Pera orange and sugarcane crops, respectively, was came by Camacho et al (2012) and Santos et al (2013).…”

“…The optimum range for each nutrient was established by leaf contents corresponding to ± ²/₃ indexes, the normal ranges of Beaufils (Urano et al, 2007;Santos et al, 2013). The order of nutritional limitation was generated in two forms: in accordance with the optimum range of leaf content or in accordance with fertilization response potential.…”
