It is important to understand the effects of oil palm (Elaeis guineensis Jacq.) plantations on water requirements. Therefore, the objective of this study was to determine soil humidity parameters in oil palm plantations at different ages of development in Tabasco, Mexico. The experiment was conducted using a completely randomized design with three replications. Four treatments were evaluated: 5-, 11-, and 25-year-old oil palm, and pasture as a control treatment. As response variables, parameters of bulk density (Da), texture, field capacity (CC), permanent wilting point (PMP), electrical conductivity (CE), saturation point (PS), and soil humidity parameters including irrigation sheet (Lr), sheet in the infiltration rate test (Lrinf), basic infiltration (Ib), accumulated sheet (Z), soil humidity retention curves (CRH), and soil humidity stress (EHS) were determined. Ib and Z values were determined in the surface layer; Lr, Lrinf, and CRH at three depths (0–30, 30–60, and 60–90 cm). The results indicate that the treatments presented significant differences (p ≤ 0.05) in all the variables evaluated; and the parameters of field capacity, permanent wilting point, initial and final humidity in the infiltration rate test, affected the humidity content in the Lr, Lrinf, CRH and EHS. It is concluded that oil palm age modifies soil humidity retention parameters and influences water requirements.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75804446","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 main reasons for this are a lack of understanding of soil nutritional status and fertilization management, which implies fertilizer misuse and results in gas emissions into the environment. In this study, the soil nutritional status of coffee plantations was evaluated along an altitudinal gradient of the Ecuadorian Andes as an indicator of soil fertilization plans. A total of 471 farmlands were selected and their pH, soil organic matter, and main macronutrients were determined. The impact of soil fertilization on nitrous oxide emissions was evaluated; for this purpose, an experimental coffee farm was chosen where different doses of mineral and organic soil fertilization were tested, and N2O emissions were determined. The results showed a negative correlation between soil organic matter, pH, and nitrate concentration with altitude. In all altitudinal strata, the nitrate concentration was higher than that of ammonium. In addition, a strong correlation was observed between soil organic matter and soil nitrate concentration. The amount of potassium decreased as altitude increased, whereas medium and high concentrations of available phosphorus were observed in all altitudinal ranges. However, significant statistical differences were found when comparing low mineral fertilization doses to organic fertilization. The N2O analyses showed that coffee plantations fertilized with mineral fertilizers emit from 300 to 1142 mg N2O m-2 into the environment. High mineral fertilization resulted in the highest N2O emissions, with statistically significant differences when compared to low mineral doses and organic fertilization. Therefore, it was concluded that changes in soil nutritional status were observed along the Andean gradient of coffee plantations in southern Ecuador, and that high doses of mineral fertilizer can have a significant impact on N2O emissions.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135264955","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 insecticide imidacloprid is frequently used to control this insect, and in some cases, it is complemented with the release of lacewings of the species Chrysoperla carnea Stephens (Neuroptera: Chrysopidae). The insecticide has been shown to be harmful to non-target insects, such as the natural enemies of this aphid, so it is necessary to find other less harmful products. The objective of this study was to evaluate the toxicity of aqueous and oily extracts of chicalote (Argemone mexicana L.) on C. carnea and to contrast it with that of imidacloprid, with the hypothesis that extracts of A. mexicana applied to the developmental stages of C. carnea generate less mortality on the predator than imidacloprid. The aqueous and oily extracts had a concentration of 30 g L-1. For imidacloprid, the recommended dose for sugarcane aphid control (0.35 g L-1) was used. Mortality and the treatments effect were evaluated by exposure methods: T1) topical on larvae, T2) egg immersion, T3) treated Sitotroga cerealella eggs, and T4) liquid ingestion in adults. Mortality, hatching and emergence variables were analyzed with a one-way ANOVA, followed by Tukey’s comparison of means (p ≤ 0.05). Treatments were classified according to the toxicity levels proposed by the International Organization for Biological Control. The aqueous and oily extracts were in toxicity class 1 for C. carnea, except in eggs treated with the oily extract (class 4). Imidacloprid was classified in class 4 when applied topically and by ingestion in adults and in class 2 in ingestion of treated S. cerealella eggs. In general, extracts of A. mexicana could be used as selective insecticides, while imidacloprid can be considered incompatible with releases of this predator.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135756093","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}

However, these models require considerable amounts of input data. Sediment data is often lacking in quantity and quality, which leads to uncertainty in hydrological models. The objective of the present study was to propose a methodological alternative based on sediment time series in the Santa Cruz de Aquismón sub-basin, San Luis Potosí, Mexico, by means of autoregressive integrated moving average models (ARIMA) and the Soil and Water Assessment Tool (SWAT) model. The SWAT model was calibrated and validated with measured flows from the National Surface Water Data Bank (BANDAS) of station 26 241 (Ballesmi). Model calibration and validation performance was assessed with Nash-Sutcliffe Coefficient (NSE), percent bias (PBIAS), and the root mean squared error (RMSE). The SWAT model fit was rated as very good. The hydrologic model results were compared to the daily sediment estimates from three months in 1985 (June, September, and November) obtained from ARIMA models. The mean absolute percent error (MAPE) was 0.571, 0.168, and 0.029, respectively. The results indicated that the use of the ARIMA model for sediment estimation is useful when there are short time series with limited information, since it allows the completion of missing data series or short-term estimates.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135756294","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 objective of the present research was to perform a morphological characterization of 83 native populations of the Ratón race and identify a subset that will represent diversity. Populations were evaluated in replicated experiments at two different locations with two planting dates per location. Twenty-six quantitative characters of the plant, tassel, ear and grain were recorded, and 14 additional characters (indices) were calculated as relationships among characters. Phenotypic diversity was examined by principal component and cluster analyses. Differences (p ≤ 0.01, p ≤ 0.05) among environments were found for 28 characters and (p ≤ 0.01) among populations for all characters, due to variation in environments and diversity among populations, respectively. Also, differences were found (p ≤ 0.01, p ≤ 0.05) in 38 of the 40 characters in the populations × environments interaction, as a differential response of the populations in the environments. Based on the repeatability index (r > 1.0), 10 characters and nine indices less influenced by the environment were selected for classification. The first two components explained 53.3 % of the total variation and it was established that the vegetative, ear and tassel characters were the most important in describing the variation; this allowed to identify a pattern of diversity associated with the area of adaptation of populations in low - intermediate - transition areas, which reveals that maize variation is closely related to altitude, and temperature and humidity gradients.

The hypothesis was that the number of orchid specimens with naturally pollinated fruits, from the central zone of the state of Veracruz, Mexico, would be more than the number of specimens that do not developed fruit naturally. The objectives of this work were: to record the flowering and fruiting periods, to characterize the orchid fruits pollinated naturally or manually. The fruit collection sites were located within the municipalities of Amatlán de los Reyes, Fortín and Tlaltetela. The work was performed between January 2019 and April 2022 (39 months). Ripe orchid fruits were collected. Morphometry was measured by recording weight (g), length (cm) and diameter of the central region (cm), complemented with a photographic record. The greatest fruit diversity of these orchids was observed and collected during the month of March. Forty-two species and their fruits were recorded, which were grouped into 8 subtribes and 32 genera. The genera with the highest number of species were: Epidendrum, Prosthechea and Oncidium, each with three species. Three species bloomed for 11 months: Platystele stenostachya, Specklinia digitale and S. tribuloides. The minor and major fruiting periods correspond to Specklinia digitale and Trichocentrum stramineum, respectively. Given the fact that in all three sites studied the greatest number of species and fruits is associated with natural pollination (27 species, 113 fruits), which exceeds the number of manually pollinated species (15 species, 51 fruits), it is possible to suggest that the largest contingent inhabits environments still compatible with the natural process of their reproduction in these sites.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80336209","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 glass transition (Tg) showed a DPa-dependent increase (LDP = 152.17 °C, IDP = 216.12 °C and HDP = 227.5 °C). Viscosity was dependent on the degree of polymerization, exhibiting thermo-mechanically stable flow behavior. The reconstituted powders exhibited Newtonian and flow-stable behavior in a concentration range of 2-50 %, temperature of 5-45 °C and pH of 2-9. The macro and micro structural properties identified in the respective fractions of agave fructans, diversify possible applications with potential interest as encapsulating material, stabilizer and prebiotic sweetener, among others that agave fructans have in the food and nutraceutical industry.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72396798","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}
