“…Subsequently, as indicated by Caraballo et al (2008), the division of the population into high and low yields indicated an inflection point of 3,420 kg ha -1 (Figure 1A), with 38 samples considered of high yield (43%) and 48 samples in the low yield category (57%). Similarly, a correlation analysis between the response variables was performed for the high (Table 2) and low yield populations (Table 3).…”

This study aimed to evaluate the nutrition of commercial soybean crops in an agricultural frontier region using the diagnosis and recommendation integrated system (DRIS) and compositional nutrient diagnosis (CND) methods, as well as identify sufficiency ranges. The study was performed by collecting leaf samples (third trifoliate leaf without petiole) at flowering from commercial soybean crops in the states of Piauí and Maranhão, Brazil, and evaluating the crop yield by analyzing macro- and micronutrients in the plant tissue of 98 samples. The DRIS and CND methods were applied based on the cataloged data, followed by the generation of norms, analysis of relationships between yield and nutrients (selecting high-yield crops by the cumulative function of the data), generation of sufficiency ranges, and comparison of methods. The relationships obtained by the DRIS and CND indices with the yield and nutrients were significant, indicating that both methods can be employed for the evaluation of leaf nutrients in soybean. The sufficiency ranges from the DRIS and CND methods presented superior nutrient ranges in relation to the values proposed in the literature for macronutrients, except for nitrogen, and greater range amplitudes for micronutrients.

“…With a decreasing yield of the sample set, Boltzmann's function (sigmoid) was established by the ratio between the yield (kg ha -1 ) of the sample set and the cumulative variance (cumulative function) of the values of D 2 , whose inflection point is presented by the sigmoid equation of Boltzmann (Caraballo, Rodriguez, & Perez, 2008).…”

Ho wever, this interaction is not important to discriminate between high-and low-yield subpopulations as proved by the F test (Table 3).…”

Mineral nutrient stress is one o f the ma jor yield gap factors, especially in floodplain and piedmont plain soil. The compositional nutrient diagnosis (CND) provides a plant nutrient imbalance index in statistical distribution patterns, which is important for adjusting the soil-plant systems specific fertilization for maintaining sustainable soil fertility. This study calculated the CND norms o f wheat (Triticum aestivum L.) and identified optimum wheat yield target of high-yielding subpopulation in farmers' fields. It also categorized the most yield limiting nutrient(s) for wheat grown. Popular high-yielding wheat was grown in 62 farmers' fields, maintaining farmers' nutrient management plan (FP) and improved nutrient management plan (INM). Nutrient composition analysis was done from 62 young foliar composite samples, collected at 7 th leaves stage (vegetative stage). The CND generic model gave 3.47 Mg ha -1 as minimum cutoff yield of the high-yield subpopulation. Nitrogen was identified as the core yield limiting nutrient for wheat in piedmont and floodplain soils. However, the yield limiting nutrients for wheat grown in the studied are were established the following series: N > S > K , Mg >P, Ca and Mn >Fe >B >Zn respectively. The CND generic model, allowed us to suggest that N, P, K, Mn, B were the factors discriminating high-from low-yielding subpopulation in piedmont plain and floodplain soils of Bangladesh.

“…Al respecto, es importante señalar que los rendimientos asociados a los puntos de inflexión que corresponden a K y Mg tienen valores menores al mínimo del rango experimental (12,34 Mg ha -1 ). Esta situación ha sido identificada como desventaja del procedimiento por otros investigadores (Khiari et al, 2001;Magallanes-Quintanar et al, 2006;García-Hernández et al, 2007;Hernández-Caraballo et al, 2008;Valdez-Cepeda et al, 2013). Esa falla del procedimiento puede ser superada mediante propuestas hechas por Hernández-Caraballo et al Los índices globales de desbalance nutrimental (DNC r 2 ) se ajustan bien a una distribución acumulada de X 2 (Figura 2) de forma similar a la reportada por Arroyo-Vargas et al (2013).…”

Una fertilización óptima es importante para mejorar la nutrición vegetal. Por lo tanto, la generación de normas nutrimentales para cada cultivo en diferentes regiones del mundo es indispensable. A través de la metodología de Diagnóstico de Nutriente Compuesto (DNC) se determinó el valor mínimo de alto rendimiento de fruto maduro en fresco del chile tipo jalapeño cv. 'Tajín', así como los rangos de suficiencia de concentraciones de los macronutrientes (N, P, K, Ca y Mg) en el tejido foliar, asociados a las normas nutrimentales. Estas normas se definieron considerando una base de datos (n = 100 observaciones). El rendimiento mínimo de referencia fue de 16,02 Mg ha-1. Los rangos de suficiencia (media ± desviación standard) de los macronutrientes en el tejido foliar fueron:
