“…Con relación a la acumulación de nutrientes en el tejido foliar, las mayores cantidades de N se concentraron en grano, probablemente, debido a la necesidad de los genotipos, para favorecer la producción de la semilla (Nehe et al 2020), seguido de hoja y cáscara, en menor proporción (Figura 1). Este comportamiento es normal en cacao, cuando las tasas de asimilación de N son más altas en hojas, se ve afectada la producción de los granos (Marrocos et al 2020b).…”

“…Se observó el siguiente orden de extracción de nutrientes en grano (Tabla 4): ICS-1: N>K>Mg>P>Ca=S>Fe>Mn>Zn>Cu=B; CCN-51 e ICS-39: N>K>P>Mg>S>Ca>Fe>Zn>Mn>Cu>B; TSH-565: N>K>Mg>P>S>Ca>Fe>Mn=Zn>Cu>B, siendo estos valores y preferencias diferentes y evidenciando el efecto genotipo, como lo sugieren Marrocos et al (2020b). La secuencia de extracción de los clones, en general, para grano fue: N>K>P>Mg>S>Ca>Fe>Mn-Zn>Cu>B, ligeramente diferente con los reportes de Furcal-Beriguete (2017).…”

La acidez del suelo limita la disponibilidad, la absorción y la concentración de nutrientes y el rendimiento del cultivo de cacao. El objetivo fue evaluar el efecto del pH del suelo sobre la concentración de nutrientes en hoja, cáscara y grano, para cuatro clones de cacao autocompatibles (ICS-1, CCN-51) y autoincompatibles (ICS-39, TSH-565), en el departamento del Caquetá. El diseño experimental consistió en un arreglo factorial con cuatro clones (factor A), cuatro niveles de pH y fertilidad (factor B) y cuatro repeticiones. Los resultados indican diferencias en la concentración de nutrientes por efecto del clon y tratamiento, siendo la acumulación de N, P y Mg en grano>hoja>cáscara, K en cáscara>hoja>grano, Ca, Fe, Mn, Zn y B en hoja>cáscara>grano, S en cáscara>hoja>grano y Cu en grano>cáscara>hoja. La concentración de P, Mg y S fue mayor y, a su vez, menor Mn, cuando aumentó el pH. El orden de extracción nutrimental en grano fue N>K>P>Mg>S>Ca>Fe>Mn>Zn>Cu>B. Con relación a los clones, CCN-51 presentó habilidad para la toma de nutrientes y alcanzar mayores producciones, incluso, en suelos con pH ≥ 5,5, lo que sugiere efecto de las condiciones edafoclimáticas y, por lo tanto, la necesidad de evaluar los clones para cada zona de cultivo.

“…In our study, the relative chlorophyll contents in leaves correlated positively with the number of pods per tree at the beginning of the harvest period (R=0.625), while at the end of the harvest period this correlation was negative (R=-0.618) (Table 1). In other studies, the negative correlation with cacao yield was found for foliar concentrations of N, P, and Cu, which was explained by the high nutritional demand for these nutrients in the productive phase of cacao (Marrocos et al 2020). More than 50 % of leaf N could be a part of the chlorophyll molecule; therefore, a significant reduction in the chlorophyll contents in leaves could indicate a re-translocation of N from leaves to the growing fruits (Pilbeam, 2015), which could further result in a negative correlation between the fruit number/weight and the leaf chlorophyll contents.…”

Cacao has high social importance in Colombia but requires cultivation techniques that improve its productivity, especially in the production of organic cacao. Pruning and organic fertilizers were assessed as treatments to increase the bean yield in an old cacao crop in Cundinamarca. The positive effects of organic fertilizer application and pruning on the pod morphometry and bean yield were established. The application of organic fertilizers with pruning, in general, increased the length and circumference of cacao pods. A negative correlation (R=-0.618) was found among the relative chlorophyll contents in leaves at the end of the harvest period and with the number of pods per tree. A positive correlation (R=0.748) was obtained between the fresh weight of pods and the dry weight of beans. No correlation was established between the relative chlorophyll contents in leaves and the bean dry weight. Pruning plus organic fertilization increased the total dry weight of beans per tree at almost 15 %, which makes pruning with organic fertilizer application the best tool for increasing yield in organic cacao production in old plantations in Cundinamarca.

“…The estimates Beau ls 7 proposed are based on the fact that the larger the size of a population sample, the better the appreciation of the mean and the variability of the sample of interest (Tables 4 and 5). For this reason, Maroccos et al 22 suggests using large databases to obtain more accurate information, with consistent diagnoses with the reality of the studied system. However, Mourão Filho 23 consider that the quality of a set of DRIS norms is not restricted only to the database, but also to the quality of the data records obtained from the levels of leaf nutrients and productivity.…”

DRIS (Diagnosis Recommendation Integrated System) is a tool used in the interpretation of leaf analyses that values the balance of nutrients, an important fact for a better assessment of the nutritional status of banana plants. Its usefulness depends on the ability to identify the nutrients that limit productivity in order to correct possible nutritional imbalances, but there is a lack of research in all crops, including bananas, to assess the accuracy of these diagnoses, which have a worrying global implication. To this end, this study evaluates DRIS norms for banana cultivation in Ecuador and the use of accuracy measurements for nutritional diagnosis, verifying the capacity of DRIS to detect true nutritional status based on plant response. The database created here contains 233 results referring to productivity and leaf contents of N, P, K, Ca, Mg, S, Cl, Fe, Mn, Cu, B, and Zn for banana trees in 2018, 2019, and 2020. Then, a field experiment evaluated doses of nitrogen and potassium and the accuracy of DRIS norms for N and K. The results show that the DRIS of banana produced in Ecuador depends on the nutrient being variable according to the crop nutritional status. The DRIS norms for diagnosis of N and K result in an acceptable accuracy to identify only deficiencies and toxicities, respectively, indicating the need for adjustments in these standards for later use in the field. Thus, there is a need for more research aiming to adopt calibrated DRIS diagnostic norms to assess the nutritional status of bananas in Ecuador.
