The research was conducted in autumn-winter seasons of 2016-2017 and 2017-2018 in Celaya, Guanajuato, Mexico. It was carried out using a randomized complete block experimental design with three replications per year and combined analysis. The experimental unit included two furrows in an area of 8.0 m2. The variables measured were those related to green and dry forage yield, number of stems, number of leaves, and plant height in the milky-mass stage. Lines L-3, L-9, and L-4 showed higher averages of green and dry forage, more stems and leaves, increased plant height, and presented a late cycle; L-18, L-20, and L-19 yielded less, with a tendency to earlier and smaller plant size. The combined analysis revealed significant differences (p ≤ 0.05); the biplot showed that lines L-17, L-5, L-9, L-20, L-4, and L-19 had higher production in the first year of evaluation for green and dry forage, number of stems, as well as a higher number of leaves.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135063135","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}

One way to face this challenge is through agroforestry systems (ASF). At the national level, there is relevant information on the subject; however, few studies have attempted to analyze trends in agroforestry scientific development over time. In this sense, it was proposed that the number of ASF publications related to food security and natural resource conservation increase on an annual basis. The objective of the present study was to perform a quantitative analysis of agroforestry research published between 1990 and 2022 from Web of Science in Mexico with a bibliometric approach. There were 204 publications related to agroforestry systems, recording an increase of 86 % in the last decade. Among the scientific journals analyzed, Agroforestry Systems and Journal of Ethnobiology and Ethnomedicine registered the highest number of publications and citations. The most frequent terms mentioned in publications over 32 years were the relationship between the effects of ASF on crops, traditional management, local knowledge, and the conservation of natural resources. The Universidad Nacional Autónoma de México (UNAM) is the institution with the highest number of research works on the subject, mainly by scientists Alejandro Casas Fernandez and Isabel Moreno Calles, both individually and collaboratively. In conclusion, the number of publications on ASF increased during the time period studied, primarily in the area of food security.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134971026","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}

During lactation, the lambs were offered pre-starter feed and water ad libitum, in addition to nursing. SAS GLM procedure was used to analyze the data. The level of polyherbal mixture had no effect on most blood components. However, as the dose of Animunin in the gel caps increased, glucose, urea, and creatinine levels decreased. In contrast, the levels of alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in the blood of lambs given the 1 g dose increased by 39.4 and 45.9 %, respectively, compared to lambs given 0 g.

This results in economic losses and environmental pollution. A fertigation system designed at the Colegio de Postgraduados (COLPOS) Campus Veracruz was established to determine the uniformity and stability of fertilizer distribution in the sugarcane crop. This study was carried out in a sugarcane plot with a farmer participant. Three levels of valve openings at the injector inlet (1/3, 2/3, and 3/3) were tested to determine the homogeneity of fertigation at the outlet of the gates and the stability of the system over time. Samples of water-fertilizer mixture were taken at the outlet of the gates. They were analyzed in the laboratory with a UV-visible spectrophotometer at 202 nm for nitrogen. It was found that the 1/3 and 3/3 valve position openings caused instability in the system. For the 2/3 opening with p = 0.359, no statistical difference (α= 0.05) was found during the time of emptying the container of the water-fertilizer mixture. Therefore, the fertigation system proved to be stable with a valve opening close to 2/3. Using the valve openings, the flow rate of water-fertilizer entering the system is uniformly mixed at the outlets of the multi-gate pipeline that pours into the crop furrows (p = 0.474 and α = 0.05). It can be concluded that in fertilization using a low-pressure irrigation system, nitrogen fertilizer is uniformly distributed when a Venturi type injector is used in a sugarcane agroecosystem with a valve opening close to 2/3.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135047861","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 was to evaluate the degradation of chote fruit for inclusion in sheep diets using in situ degradation and to identify some physiological variables in the rumen. Six rumen fistulated lambs with a live weight of 30 ± 2 kg were adapted for 11 days to the following experimental diets: T 0: 0 % chote fruit; T 15: 15 % chote fruit, and T 30: 30 % chote fruit. In situ degradation of chote fruit was determined and experimental diets were analyzed with a 3 × 3 crossover design. The results show that after 3 and 6 h, chote fruit at T 30 presented greater degradation (p ≤ 0.05).

This study evaluated the effect of food and water supplementation by capture-mark-recapture using camera traps at the UMA San Huberto, Sonora, Mexico. During the winter of 2015-2016, male mule deer counts and detection histories were collected at 62 photo-trapping stations spread across four supplementation treatments: 1) water and food, 2) water, 3) food, and 4) no supplementation. In addition, to assess the impact of natural vegetation on trough and feeder utilization on the ranch, the Normalized Difference Vegetation Index was calculated using Landsat 8 satellite images. A log-Poisson regression model for deer counts per photo-trapping station found that food supplementation increased mule deer numbers by 42 % when compared to stations without food supplementation. Vegetation biomass had no effect on the frequency of use of feeders and waterers in any of the treatments. According to the multistate model for detection histories, male mule deer at waterers receiving food-only supplementation are more likely to remain in that treatment than to move to either of the other two treatments (water and feed or water). This finding suggests that food-only supplementation is more effective in retaining male mule deer.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"44 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77823155","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":"131 1","pages":"0"},"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 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).

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":"18 1","pages":"0"},"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}
