BACKGROUND Colombia is known for its production of fine and aromatic cocoa; however, the lack of homogeneity in the ripeness stage of cocoa fruit affects the final quality of cocoa beans. Therefore, the aim of this work was to identify parameters that can be use as indicators of ripeness in cocoa fruit in order to homogenize the characteristics of raw cocoa used in the production of cocoa‐products industry. The parameters evaluated were fruit, seed and pod weight, firmness, color, polar and equatorial diameters of the fruit, seed moisture content, total titratable acidity, pH, and total soluble solids of pulp. RESULTS Factors such as seed weight, firmness, diameters, total soluble solids, pH, and acidity were affected by the clone factor, whereas seed weight, pH, and total titratable acidity were affected by ripeness stage. CONCLUSION Identification of indicators of ripeness for cocoa fruit is a complex task due to the influence of the clone on the evolution of the physicochemical characteristics of cocoa fruit during its maturation process. Thus, indicators must be developed for each clone, and at least two parameters among color, pH, and total titratable acidity should be used to determine the ripeness stage of cocoa fruit. © 2019 The Authors.

Andean blackberry is a fruit recognized by its health benefits associated with its high content of bioactive compounds. However, it is also one of the most perishable fruits because it does not have a protective cuticle, and it shows high respiration and ethylene production rates. Furthermore, it is susceptible to microbiological attacks. During harvest and commercialization, the highest percentage of losses is caused by factors such as the maturity stage, harvest practices and containers, and marketing packages. The current work aims at studying the effect of the package on fruit quality, for which the harvested fruits were placed in clamshells, traditional wooden and plastic crates with a capacity of 7 kg. The quality of the fruit was evaluated by counting in situ , damage by bruising, cuts, deformations, microbiological attacks, missing of the peduncle, and non-uniform pollination. Damage analysis included the evaluation of different regression models considering information criteria and significant parameters (P ≤ 0.05). The use of traditional packages led to higher damage from cuts and bruises. Although in clamshells there was a higher probability of finding healthy fruits, a proposal for its redesign is proposed to guarantee a better quality and shelf life of the Andean blackberry fruits.

La asociación de usuarios del Distrito de Adecuación de Tierras de Gran Escala del Río Zulia (ASOZULIA) Norte de Santander, con un área de influencia de 45.536 hectáreas, está interesada en la planificación productiva de su territorio. Dentro de sus actividades agropecuarias se encuentran el arroz (12.000 a 17.000 ha), la palma de aceite (1.534 ha), cítricos (limón, naranja; 346 ha), caña de azúcar (100 ha) y la ganadería. Su principal sistema de producción durante más de 50 años es el cultivo de arroz, sistema que presenta reducción de la productividad (7 a 3 tha), degradación del suelo y problemas de plagas y enfermedades, debido entre otros al uso continuo del fangueo como sistema de preparación de suelos. Adicionalmente, a pesar de tener el distrito de riego del río Zulia una concesión de 13,5 m3.s1, en épocas de verano la oferta hidrica es mucho menor como, por ejemplo, la correspondiente a los meses de febrero a marzo de 2016, con un caudal en la bocatoma del distrito de 10,8 m3s'y una captación real del distrito de solo 6 m.s' Asimismo, la construcción del nuevo acueducto para el área metropolitana de la ciudad de Cúcuta tomará 2,95 m3s del caudal antes de la bocatoma que provee agua al distrito, lo que disminuirá aún más la disponibilidad de agua para riego en esa región. Por lo anterior, se requiere la recuperación de los suelos para el establecimiento de nuevos sistemas productivos que demanden un menor consumo de agua y sean una alternativa viable para los productores.
