The objective of this research was to evaluate quality variables in avocado (Persea americana Mill.) cv. \"Hass\" during storage in modified atmosphere packaging (MAP) at 8 °C and contrast them to those obtained during storage at room temperature (RT) and refrigeration (REF). Fruits at physiological maturity were stored in MAP bags with a thickness of 0.20 mm. A completely randomized design was used; factors were: type of storage (RT 21 °C, REF 8 °C, and MAP 8 °C), storage time (8, 16, 24, and 32 days), and ripening time after storage (2, 4, and 6 days). Quality variables were firmness (penetration force), total color difference (ΔE) in exocarp and mesocarp (colorimeter), pH (potentiometry), and total soluble solids (TSS, refractometry). Avocados stored in MAP maintained (p > 0.05) firmness, which was higher compared to REF and RT during the storage period. Firmness retention for avocados at RT, REF, and MAP, at day 16, was 5.7, 32.6, and 87.2%, and at day 32, it was 0 (no reading), 9.5, and 78.2%, respectively. Total color difference in exocarp and mesocarp, pH, and TSS ranged from 3.8 to 25.6, 3.2 to 20.3, 6.7 to 7.1, and 5.3 to 7.7 °Brix, respectively. During the storage period, fruits stored at MAP showed a firmness, ΔEexocarp, and ΔEmesocarp similar to those of fresh fruit. Type of storage showed no effect on pH and TSS during the storage period. The package for modified atmosphere at 8 °C allows to prolong the shelf life of “Hass” avocado for a period twice as long as that at room temperature, based on the fact that changes in firmness and color are reduced, properties that are important quality benchmarks.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"66 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75153852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to identify four varieties of peach (Prunus persica L. Batsch) (CP-03-06, Oro Azteca, Oro San Juan, and Cardenal), based on the color of digital images of the upper and lower side of leaves, represented by two color spaces: RGB (red, green, blue) and HSV (hue, saturation, value). The classifiers were trained and evaluated based on six data input scenarios, defined by the combinations of the upper, lower, and both sides of the leaf with the RGB and HSV color spaces. The three machine learning classifiers (SVM, RF, and MLP) achieved their best prediction performance when they examined the color characteristics of the upper side of leaves transformed to the HSV color space. The SVM classifier outperformed RF and MLP. SVM achieved a global average correct classification accuracy of 84.1 %, F1 macro of 83.7 %, and area under the ROC curve (AUC macro) of 0.93.

One alternative for its ecological management is the use of repellent aromatic plants. The hypothesis of this study is that the aromatic plants that diminish the attraction of B. tabaci to tomato have the capacity to prevent the infestation of this pest in the tomato crop when an intercropping system of tomato-aromatic plant is established. The objective of this study was to evaluate by means of the technique of olfactometry, the response of B. tabaci to the volatiles emitted by the crushed leaves of tomato and by the combination tomato + aromatic plant. The aromatic plants with highest activity in the olfactometry tests were intercropped in a tomato crop in the field. In the bioassays of olfactometry, a significant decrease was observed in the attraction of B. tabaci to crushed leaves of tomato + some aromatic plants compared with the attraction to tomato alone. The repellence indices (IR) showed that the aromatics Lavandula angustifolia Mill. (IR, 0.1), Petiveria alliacea L. (IR, 0.48), Petroselinum crispum Mill. (IR, 0.28) and Thymus vulgaris (IR, 0.5) had the greatest effect as repellent of adults. By integrating these aromatic species through intercropping in the tomato field crop, no significant difference was observed in the population density of eggs and adults of B. tabaci in the tomato foliage in regard to what was observed in the control (only tomato). The incidence and severity of viral symptoms did not decrease from the presence of the aromatic species intercropped in the tomato crop.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"115 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79108623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2011, 2012, and 2013, 67 experiments on maize response to N were distributed and conducted in five edaphoclimatic regions of Mexico, with native and improved maize in rainfed and irrigation conditions. The treatments were: (1) fertilization with N, P, and K; (2) omission of each nutrient; and (3) no fertilization. The experimental design was a randomized complete block design, without replications. Production functions were estimated for rainfed and irrigation conditions in edaphoclimatic regions, for yield as a function of attainable yield classes, amount of N applied, and soil organic matter content. The production functions were used to estimate economic optimum N rates, with: (1) the current N/maize price ratio for the attainable yield classes and soil organic matter contents, as well as optimum economic yields and net income; and (2) the increased N/maize price ratio, that reduced the economic optimum N rates and fertilization costs, without significantly decrease of the economic optimum yields and the net income; this also  reduces  N losses and environmental pollution.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"21 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76503809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mixteca region, covers a wide area of central Mexico, characterized by a semi-arid climate, eroded calcareous soil, and rural poverty. With the aim of proposing technologies for improving soil quality and increasing the availability of nitrogen and phosphorus, an experiment was conducted using green manures: Canavalia ensiformis, Dolichos lablab, Leucaena leucocephala and Avena strigosa and Phaseolus vulgaris, that would ensure a balance between N and P release and the requirements of maize cultivation. The rate of enriched soil mineralization with green manures was determined through incubation, controlled for 15 days with CO2 emissions using an OxiTop OC110® kit as an indicator of decomposition. CO2 emissions were greatest in the soil established with Leucaena leucocephala and least in the soil with no fertilizer, with emissions descending in the following order: Leucaena leucocephala > Canavalia ensiformis > Avena strigosa +Phaseolus vulgaris > Dolichos lablab > soil without green manure. It is assumed that a greater flow of CO2 is accompanied by greater mineralization and release of nutrients. The Ntotal in the soil treated with green manures was similar and greater than that of the soil without fertilizer. Soil treated with Avena strigosa+Phaseolus vulgaris contained the highest values of Nmineral (N-ammonium + N-nitrate). POlsen content in soils with green manures was double that of the soil without fertilizer. Incubation provided the opportunity of identifying those green manures with higher agronomic potential in the area under study. The biomass comprising Leucaena leucocephala leaves and tender stems constitute an alternative for improving soil by providing OM. However, when considering the availability of N and P, the Avena strigosa+Phaseolus vulgaris combination is a superior alternative for meeting the needs of maize cultivation.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"5 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80071599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since ancient times, it has been used as a healthy product due to its sweetening and healing properties. In 2020, Mexico produced 54 121 tons (Mg), which ranked the country as the tenth largest producer in the world. The hypothesis was that current honey prices can be explained by previous prices and that they influence the increase in the population of hives and the production of honey in Mexico. To test this hypothesis, the objective of this research was to develop a forecast model for the annual average prices of honey in Mexico (AAPH). The data comprised the 1966 to 2019 prices and the Box-Jenkins methodology of Autoregressive Integrated Moving Average (ARIMA), with and without intervention, was used. The parameters of the models were estimated with the maximum likelihood method of the SAS® software, while the structural change was calculated with the corresponding library (strucchange) of the R software. A model based on the AAPH series was adapted for the 1966−2019 period and validated with data from 2018 and 2019. The series presents five periods of trend structural changes of AAPH: 1966−1985; 1986−1995; 1996−2003; 2004−2008; and 2009−2019. The best estimated model without intervention was ARIMA (1, 1, 1) and the best model with intervention was ARIMA (1, 1, 0), which indicates that the prices of previous years can explain the AAPH. The predictions had a mean absolute percentage error (MAPE) of 8.16 % for the model without intervention and 4.02 % for the model with intervention. Both estimated models suggested that the AAPH have an upward trend in the medium term. The ARIMA model with intervention provided a more accurate estimation of the AAPH and information to plan and make decisions for the next five years.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"26 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81568285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such type of studies is essential to propose actions for sustainable management of the species and the habitat by the rural communities. The objective of this study was to describe the populational attributes of M. temama (distribution, population abundance, and patterns of activity) in the Sierra de Zongolica. Information was gathered through interviews, spoor detection and camera trapping from September 2014 to May 2015. To identify the sites where the deer is present, 76 inhabitants of four municipalities of the Sierra de Zongolica were interviewed. In the localities described with presence of the deer, 20 walking trails 300 m long by 1 m wide were identified. Six of the trails were in primary vegetation (1.8 km), 10 in secondary vegetation (3 km), and four in the area of cultivation (1.2 km) where 54 spoors were recorded (45 hoofprints and nine droppings), equivalent to nine signs of deer per km. The population of M. temama was higher in the farming area than in primary or secondary vegetation. In the 43 stations of camera traps, 71 independent images of M. temama were obtained. Of these images, 79 % were between 18:00 and 05:00 h, indicating a pattern of crepuscular and nocturnal activity. This species had a relative abundance index of 2.5 brockets per km2 in the Sierra de Zongolica, suggesting a population susceptible to management under the system of Management Units for Conservation and Sustainable Use of Wildlife (in Mexico, UMAs).","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"27 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82484445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plants produced from seeds of four seed trees were used, which were subjected to seven doses of phosphorus: 0, 25, 50, 75, 100, 125 and 150 mg P dm-3. The experiment was carried out in a 7 × 4 factorial arrangement, with four replicates and using containers with 5 dm3 of a Red Eutropheric Latosol type soil. The response variables measured were monthly plant height, plant collar diameter at 90 d, dry biomass weight of leaves, roots, stems and branches, and phosphorus use efficiency of leaves. The variations of the characteristics evaluated as a function of phosphorus concentration were analysed by means of polynomial regression equations. Phosphate fertilization is necessary for the growth and development of C. citriodora plants. Plants of the four C. citriodora seed trees from different provenances responded differentially to phosphorus doses. It was found that the optimum amount of phosphorus ranges between 30 and 100 mg dm-3 according to the characteristics evaluated and the seed tree.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"47 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81097180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
