México es uno de los países con mayor producción de aguacate en el mundo y la variedad mayormente plantada es la Hass, además que Michoacán, México figura como el principal productor de aguacate con un 80% seguido de otros estados como Jalisco, estado de México y en Veracruz existe una superficie plantada en la parte central del estado que necesita ser caracterizado. El objetivo de esta investigación es tipificar la zona productora de aguacate en la zona de alta montaña de Veracruz, México. La zona de productora de aguacate en la región de altas montañas, Veracruz, México, está integrado por los municipios de Alpatlahua, Calcahualco, Coscomatepex e Ixhuatlan del café, lugar donde se aplicó una encuesta entrevistando a productores a través de una entrevista con el instrumento denominada como cuestionario semiestructurado con preguntas abiertas y cerradas; se realizó el análisis de la información de manera sistematica con análisis descriptivo y multivariado de componentes y correspondencia, además, para algunas variables se realizó análisis paramétrico y no paramétricos de los datos. Los resultados obtenidos nos agrupa a productores pequeños, con el 80% de hombres y el resto integrados por mujeres, la mayoría de los productores saben leer y escribir, también se observó que se dedican a otras actividades diferentes al cultivo de aguacate. El productor aguacatero posee conocimiento tácito en el manejo del cultivo desde la etapa plantación hasta la producción del cultivo. Los productores poseen experiencia en el manejo de otros cultivos, esto es porque tiene la finalidad de obtener otros ingresos adicionales.

Objective: To know the variables of the reproductive component of materials for manual cross-pollination purposes, for which the search for sexual synchrony is emphasized. Design/methodology/approach: Four materials were analyzed, two with white pulp and two with red pulp, about which it is unknown if they present sexual self-incompatibility, and the synchrony in flowering is also unknown. The flowering phase and the variables that can shed light on its reproductive behavior were analyzed Results: It was found that the red materials present strong hercogamy, they cannot self-fertilize. There is also no floral synchrony, but there is closeness between the date of anthesis in a pitahaya with white pulp and a red one, which would allow promoting cross-pollination. Study limitations /implications: Hylocereus spp. is consumed in a large part of the world and has acquired a very strong importance since the industrial demand is increasing; however, several of the genotypes used in commercial production in Mexico show low fruit set compared to high floral emission, which is considered self-incompatibility. Findings/conclusions: The presence of hercogamy, stronger in the red-fleshed materials, indicates the existence of sexual self-incompatibility, explaining the fact that the materials emit a large number of flowers, but do not achieve fruit setting.

Objective: To evaluate fertilization with vermicompost and NPK mineral fertilizer in young Persian lime (Citrus x latifolia Tanaka ex Q. Jiménez) trees. Design/Methodology/Approach: A randomized block design was established with eight treatments and four repetitions: T1, 0 kg tree-1; T2, 90-22.5-22.5 N-P-K kg ha-1; T3, 2 kg tree-1 of vermicompost; T4, 3 kg tree-1 of vermicompost; T5, 4 kg tree-1 of vermicompost; T6, 90-22.5-22.5 N-P-K kg ha-1 + 2 kg tree-1 of vermicompost; T7, 90-22.5-22.5 N-P-K kg ha-1 + 3 kg tree-1 of vermicompost; and T8, 90-22.5-22.5 N-P-K kg ha-1 + 4 kg tree-1 of vermicompost. The study variables were tree height, stem thickness, crown diameter from North to South (N-S) and East to West (E-W), soil pH, and soil moisture (%). The data were statistically analyzed applying the MINITAB V.17 statistic through an ANOVA (P≤0.05), while a multivariate analysis was used for the means comparison. Results: The tree height and crown diameter variables had different results in the Persian lime trees treated with 4 kg tree-1 of vermicompost (T5). The tree canopy had a similar development than T5 with vermicompost treatments combined with NPK mineral fertilizer. Study Limitations/Implications: Conventional lime production indiscriminately uses synthetic fertilizers, polluting natural resources. Organic fertilizers are a nutritional alternative for the trees. Findings/Conclusions: The vermicompost treatment efficiently maintains adequate soil moisture during the dry season, improving the growth and development of Persian lime trees.
