“…In the postharvest period, the fruits are refrigerated at 5 °C for 15 days, when they are sent to distant cities such as Monterrey. High dry matter values (e.g., 262%) prevent weight loss, cold damage, and pulp damage after maturation (Escobar et al, 2019).…”

Objective: To characterize the avocado production system in Huatusco, Veracruz. Design/Methodology/Approach: Interviews based on the snowball method were applied to avocado producers in Huatusco, Veracruz. Meanwhile, fruit and water samples were used to perform a multiresidue analysis of pesticides. Results: The monoculture plantations are rainfed. They have a density of 100-150 trees ha-1. The Hass variety predominates in Andosols, with 5-100% slopes. Most of the producers (92%) carry out conventional management, applying pesticides and chemical fertilizers. Herbicides and brushcutters are used to control weeds. No pesticides were detected in the water samples, while Imidacloprid, Thiabendazole, and alpha-Cypermethrin were identified in a fruit sample, with 0.0038 ± 0.0014 mg/kg, 0.0022 ± 0.0009 mg/kg and 0.0703 ± 0.000 mg /kg concentrations, respectively. These concentrations fall within the limits allowed in Mexico. Study Limitations/Implications: A detailed and frequent sampling of avocado fruits should be carried out to determine pesticide residues. It is also necessary to analyze samples of running water near the orchards to prevent pollution. Findings/Conclusions: The empirical knowledge of the producers about the type of soil is more precise than the scientific classification: they identify five classes of soils beyond Andosols. Additionally, there is a marked inequality in land tenure, since large-scale producers (25% of all producers) own 86% of the established area. Although, in a preliminary sampling, pesticide concentrations did not exceed the limits of residues allowed in the avocado pulp, the number of pesticide applications should be reduced.

“…A. Baja Productividad y causas en el sector agrícola En la primera y segunda tipología, se identificó una similitud entre los autores [5] y [6], ambos estudios identificaron que la baja productividad es un problema constante en el sector agrícola. Además, el primer estudio encontró la presencia de este problema mencionado en MYPES, tal como es el caso de estudio de la presente investigación; sin embargo, plantean diferentes causantes a este problema.…”

“…Además, el primer estudio encontró la presencia de este problema mencionado en MYPES, tal como es el caso de estudio de la presente investigación; sin embargo, plantean diferentes causantes a este problema. Por un lado [7], indica que la baja productividad se debe a la mala supervisión y la falta de conocimiento de las buenas prácticas agrícolas en el proceso de la campaña, la cual afecta la calidad del fruto y planta. Por otro lado, según [8], manifiesta que existe una baja productividad debido al bajo control en el proceso de poscosecha, ya que se pudo observar que los frutos no terminaron de madurar y presentaron daños en la pulpa, deformaciones, poseían olores y tenían heridas abiertas limitando el crecimiento del cultivo.…”

The investigation begins with an analysis for the case study belonging to the agricultural sector. For which, the low production productivity of Hass avocado with 3 tons/ha was identified as a technical gap, comparing it with the national average productivity of 11.2 tons/ha. For this reason, the main problem is reflected in the Micro and Small Enterprises (MYPES) that produce Hass avocado from Pitipo, worrying farmers about their next harvests. In this way, a study was carried out through interviews and data obtained by the farmers. Therefore, causes were identified such as the presence of pests and pathogens causing damage to both the plant and the finished fruit in the healing process; On the other hand, the size and weight outside the quality standards in the filling process are an important factor in the agricultural sector, since the Hass avocado does not meet the necessary requirements, it is discarded from production and the plants are damaged in the process. healing process produce losses for future campaigns. Therefore, the present research work aims to increase productivity through the tools of Total Quality Management (TQM) that will give us the execution and control, complemented with good agricultural practices (GAP), which seeks that the farmers have greater knowledge of the parameters and guidelines established by the National Service of Agrifood Health and Quality (SENASA). At the end of the implementation, the result is expected to obtain a yield of 2,514 kg ofHass avocado for 38 plants, that is, to increase productivity by 35%.

“…Researchers have reported that preharvest factors influence the fruit composition of Hass avocados [2]. The dry matter (DM) of fruit pulp is the most widely used indicator internationally to determine quality attributes and minimize defects in fruit pulp [3]. There are other harvest maturity indicators that have been used to evaluate quality attributes, with the oil content (OC) being the most studied to identify the ideal harvest time.…”

Accurate dry matter determination (DM) in Hass avocados is vital for optimal harvesting and ensuring fruit quality. Predictive models based on NIRS need to capture fruit DM gradient. This work aimed to determine the DM content in Hass avocado whole by NIRS scanning different fruit zones. Spectra were recorded for each zone of the fruit: peduncle (P), equator (E), and base (B). The calibration and validation included fruit from different orchards in two harvest cycles. The results show a DM gradient within the fruit: 24.47% (E), 24.68% (B), and 24.79% (P). The DM gradient was observed within the spectra using the RMSi (root mean square) criterion and PCA. The results show that at least one spectrum per fruit zone was needed to represent the variability within the fruit. The performances of the calibration using the whole set of data were R2: 0.74 and standard error of cross-validation (SECV) = 1.18%. In the validation stage using independent validation sets, the models showed similar performance (R2: 0.75, SECV 1.15%) with low values of the standard error of prediction (SEP): 1.62%. These results demonstrate the potential of near-infrared spectroscopy for high-throughput sorting of avocados based on their commercial quality.
