Resumo: | The objective of this work was to establish DRIS norms for evaluation of nutritional status of cactos pear of the Gigante cultivar grown under organic fertilization in semiarid conditions. Cladode macro and micronutrient contents and dry matter yield of 72 plots were evaluated. The experiment was conducted in a randomized block design with three replicates, using a 4×3×2 factorial arrangement consisted of four bovine manure rates (0, 30, 60, and 90 Mg ha-1 ano-1), three spacings (1.00×0.50, 2.00×0.25, and 3.00×1.00×0.25 m), and two production cycles (600 and 930 days). The data were separated into high-yield population (HYP) and low-yield population (LYP), above and below 19.93 Mg ha-1 cycle-1, respectively. The mean, standard deviation, coefficient of variation, variances, and variance ratios of all bivariate relations between nutrients were calculated for the establishment of DRIS norms, considering the direct (A/B) and reverse (B/A) form. The selection of direct and reverse relations between nutrients to compose the DRIS norms was based on the variance ratio between LYP and HYP (S2b/S2a). The sixty-six relations between cladode nutrient contents that presented the higher ratios between the variances in the LYP and HYP (S2b/S2a) were chosen. The DRIS norms established make viable the use of leaf diagnosis as an evaluation method of nutritional status of cactos pear of the Gigante cultivar grown under organic fertilization in semiarid conditions. |

Utilizaram-se teores de macro e micronutrientes dos cladódios e produtividades de matéria seca (PMS) de 72 parcelas, de um experimento com quatro doses de esterco bovino (0; 30; 60 e 90 Mg ha-1 ano-1), três espaçamentos (1,00 x 0,50; 2,00 x 0,25 e 3,00 x 1,00 x 0,25 m) e dois ciclos de produção (600 e 930 dias após o plantio), dispostos em esquema fatorial 4 x 3 x 2, delineamento em blocos casualizados e três repetições. O banco de dados foi separado em população de alta (PAP) e de baixa produtividade (PBP), acima e abaixo de 19,93 Mg ha-1 ciclo-1, respectivamente. Foram calculadas a média, o desvio-padrão, o coeficiente de variação, as variâncias e a razão das variâncias de todas as relações bivariadas entre nutrientes, considerando a relação na forma direta (A/B) ou inversa (B/A). A seleção da relação direta ou inversa dos nutrientes para compor as normas DRIS foi baseada no método da razão das variâncias entre a população de baixa e a de alta produtividade (S2b/S2a). Foram escolhidas 66 relações entre os teores de nutrientes nos cladódios que apresentaram as maiores razões entre as variâncias da PBP e PAP (S2b/S2a). As normas DRIS estabelecidas viabilizam a utilização da diagnose foliar como método de avaliação do estado nutricional da palma forrageira ‘Gigante’ cultivada com adubação orgânica em condições semiáridas.Universidade Federal Rural do Semi-Árido2019-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/801210.1590/1983-21252019v32n411rcREVISTA CAATINGA; Vol. 32 No. 4 (2019); 952-959Revista Caatinga; v. 32 n. 4 (2019); 952-9591983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8012/10105Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessTeixeira, Marcelo BatistaDonato, Sérgio Luiz RodriguesSilva, João Abel daDonato, Paulo Emílio Rodrigues2023-07-20T17:54:54Zoai:ojs.periodicos.ufersa.edu.br:article/8012Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:37.921824Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
