The pesticides used in current formulations exhibit toxicity and carcinogenic effects on consumers. This study aimed to investigate the pediculicidal activity of the essential oil from Eucalyptus Globulus leaves, with the intention of adding it as an active ingredient in pediculicidal formulations to replace harmful chemicals. Design/methodology/approach: In vivo tests were conducted to assess the repellency and mortality of the essential oil obtained through hydrodistillation. The major components were determined through gas chromatography-mass spectrometry analysis. Additionally, proximate, and chemical composition analyses were performed on the eucalyptus leaves using ASTM E871, ASTM E872, ASTM D1104, TAPPI T264, TAPPI T207, ASTM D1106, and ASTM D1104 methods. Results: A repellency of 66.66% and 100% mortality within 2.26 minutes were obtained in the in vivo tests. The yield of hydrodistilled essential oil was 4 mL/kg, primarily composed of 71.04% 1,8-cineole, 18.94% 4-Ethyl-m-xylene, 2.72% γ-Terpinene, and 1.23% L-α-Pinene. Furthermore, the composition of eucalyptus leaves was determined as 61.25% moisture, 30.32% volatile matter, 6% ash, 2.40% fixed carbon, 11.22% acetone extractives, 33.03% water extractives, 31.49% lignin, 69.33% holocellulose, 62.09% cellulose, and 7.24% hemicellulose. Limitations on study/implications: The pediculicidal activity study was conducted solely on the essential oil, and further testing on the formulation of the finished product is necessary. Findings/conclusions: The pediculicidal activity study was conducted solely on the essential oil, and further testing on the formulation of the finished product is necessary.","PeriodicalId":153856,"journal":{"name":"Agro Productividad","volume":" 42","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139142527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design/methodology/approach: A Moving Average Time Series Smoothing method was used to reduce the variation of a data set, and separate cyclical, seasonal, and OLS variations to calculate the trend line. Results: The Seasonal Component (SC) indicates that in autumn-winter the AWECP is volatile above the annual average by 6.3 % while in spring-summer it declines by 9.13 % on average. The price volatility is largely explained by external factors and the biological process of poultry animals throughout one year. The cyclical component (CC) was 34 months and occurs irregularly. Limitations on study/implications: This research focused on finding the SC, T, and CC, but not their respective indices. To make short-term forecasts, it is necessary to calculate the indices and compare them to other time series analysis methodologies. Findings/conclusions: The analysis of the AWECP in the Mexico Valley indicates the presence of SC and an upward CC trend in the time series. The AWECP volatility has harmful effects on the basic basket of the middle and lower-class population in the Mexico Valley given that this food is the most complete, cheap, and accessible source of animal protein in the Mexican market.","PeriodicalId":153856,"journal":{"name":"Agro Productividad","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139142621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, these provide the mineral content in grains, which is a nutritional quality-related parameter. Limitations on study/implications: increasing the number of hybrids, different fertilization rates, different soil conditions, and crop management practices should be evaluated to assess whether these influence/inhibit the final nutrient concentration and total removal in grain. Findings/conclusions: The total grain nutrient removal values varied as a function of hybrids, yield goal, and nutrient concentration in tissues. These values allow the adjustment of current fertilization rates. The same hybrids under different management practices (fertilization dose), or soil types, substantially influence the grain nutrient concentration and therefore total nutrient removal.","PeriodicalId":153856,"journal":{"name":"Agro Productividad","volume":"98 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139146282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In them, nitrogen plays an important role in the yield and quality of the wheat grain. For these reasons, the objective of this research was to determine the effect that nitrogen has on yield, grain protein, and the vitreous grain percentage. A field experiment, planted on December 16, 2009, was conducted at the Institute of Agricultural Sciences of the Universidad Autónoma de Baja California. The experimental design was of complete randomized blocks with four repetitions. The assessed treatments were 0, 105, 210, 315, and 340 kg of N ha-1 (N0, N105, N210, N315 and N340, respectively). The sown seed was Aconchi F-76 variety crystal wheat. The evaluated variables were grain yield, protein content, and vitreous grain quantity (without white belly). The results indicated that the 210, 315, and 340 kg of N ha-1 treatments affected the yield, protein content, and white belly decrease in the grain. Grain quality is therefore improved with these nitrogen doses, in relation to the quality of the harvested grain in the plots with 0 kg ha-1 and those cultivated with 105 kg ha-1.","PeriodicalId":153856,"journal":{"name":"Agro Productividad","volume":" 34","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139142979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design/methodology/approach: 23 lines of the 'Maradol' type were evaluated at Antunez Michoacan, Mexico. Initially, the plants' height, stem circumference, number of leaves, and first fruit height were recorded. During their development, outstanding plants were identified, and their self-pollinating was promoted. In the fruits, their polar and equatorial circumference, shape index, weight, width and pulp firmness, and soluble solids were assessed. Results: The plants' development was different, their variability between lines allowed identifying morphological characteristics of interest. Only 10 lines had this condition. The number of fruits formed over covered flower buds and collected fruits on formed fruits was reduced. The fruits´ characterization, except for their soluble solids, showed differences. Multivariate analysis indicated variability associated with each principal component. Limitations on study/implications: Currently in Mexico, there are few papaya varieties, the 'Maradol' variety being dominant, and vulnerable to phytosanitary problems over time. However, developing varieties and seed production is challenging and the pollination control of the plants necessarily intervenes. Findings/conclusions: Out of 23 assessed papaya lines, only 43.48 % reported outstanding plants. Inside these lines, between 5 and 10 % of the plants were chosen. In the developmental progress from the covered flower buds’ stage to formed and collected fruits, only 28 % of fruits were obtained. The selected lines showed fruit variability.","PeriodicalId":153856,"journal":{"name":"Agro Productividad","volume":"24 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139147867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design/methodology/approach: The fall armyworm incidence was determined through the “five of golds” systematic sampling, composed of 20 plants per sampling point (100 plants in each plot). This assessment was conducted in 15 plots of native corn in the municipality of Cherán, Michoacán. Control bioassays were also tested, in the laboratory and field; where rue essential oil, garlic extract, cypermethrin, and an absolute control (water) were evaluated. Results: The highest fall armyworm incidence (18%) occurred in a corn plot at Andasticua. In the laboratory, cypermethrin induced the highest fall armyworm mortality (100%), followed by rue essential oil (83%). In the field, both the insecticide and the rue essential oil reduced lepidopteran incidence. The main component of the essential R. graveolens oil is the semivolatyl cinnamoyl chromen (IUPAC name: 2-(3-phenylprop-2-enoyl)chromen-4-one).

Design/methodology/approach: The data on the cultivated area with the rainfed sugarcane such as topography, principal properties of soil fertility, crop yields for the beginning of the 21st century, current climatic data from the meteorological stations and future ones based on existing climate change scenarios were analyzed. Then, by means of a physiological model of this crop based on biological, climatic and soil characteristics, proposed by IIASA/FAO, the current and future agricultural productivity of sugarcane was calculated. The actual productivity calculated with this model was compared with the observed data. Then, the productivity of this crop for the end of the 21st century was calculated. The comparative impact on the productivity of the expected changes in some climatic components and corresponding expected modification in soil fertility was assessed. Results: The results of calculations indicate that if the CO2 concentration in the atmosphere increases by 2 or 2.7 times at the end of the 21st century and the current varieties of sugarcane and their crop management will conserve, the yield of sugarcane will decrease up to 20% depending on the climate change scenario and location of the plot. The main climatic factor influencing the decrease in sugarcane productivity is the expected decrease in precipitation. Limitations on study/implications: Monthly average climatic variables are used for both current and future productivity calculations since there are no estimates of daily data. There are also no predictions on the development of crop management technology as well as on the expected change in pests and diseases for the end of the 21st century. Findings/conclusions: The IISA/FAO physiological model of sugarcane growth based on agroecological principles, considering even limited number of climatic variables, is useful for calculating of sugarcane productivity with correlations greater than 90% for calculated and observed data. This allowed us to estimate the expected impact of climate change in the productivity of rainfed sugarcane in Veracruz State of Mexico at the end of 21st century.","PeriodicalId":153856,"journal":{"name":"Agro Productividad","volume":"21 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139147778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
