Genetic advancement in yield is crucial to satisfy the demand of the growing world population. The aim of this study was to estimate genetic progress in agronomic traits of varieties released in El Bajío (Mexico) between 1975 and 2016 under normal and restricted irrigation. The hypothesis was: with the breeding of wheat varieties for over 40 years for the region of El Bajío, advances have been made in grain yield. The genotypes planted were Salamanca S75, Cortazar S94, Bárcenas S2002, Urbina S2007, Alondra F2014 and Cisne F2016 during the 2016-17 and 2020-21 agricultural cycles in three irrigation schedules, two at 0 and 55 days after planting, three at 0-45 and 75 and four at 0-45-75 and 100 days after planting. Phenology, yield and its components were measured, and the treatment design followed a randomized complete block design with arrangements in subdivided plots and three replications. Using the weighted phenotypic model and its graphical representation through the SREG biplot, it was determined that recently released varieties outperformed the grain yield of older varieties in all three irrigation schedules. The varieties released between 1975 and 2016 displayed no changes in days to heading and maturity, since only early genotypes were advanced in the selection process. For grain yield, a genetic progress was obtained of 26.3, 41.6 and 37.6 kg ha-1 year-1 for the two, three and four irrigation schedules, respectively, which was related to an increase (p ≤ 0.01) in aerial biomass and a higher number of spikes and grains per unit area.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"109 3","pages":""},"PeriodicalIF":0.3,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139383286","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}

This study investigated the stability of two dynamic systems, represented by an inverted pendulum and a simple approximation of an aircraft wing surface exposed to aerodynamic forces. This study illustrates the advantages of time-domain simulation for solving the differential equation of motion. The simulation used the Euler integration approach for various system parameters. Essentially, an aircraft in flight must constantly maintain pitch stability, which, in practical considerations, can be compared to the mechanism of a rotary motion represented by the up-swinging motion of an inverted pendulum. The pendulum may conserve the same concept as an aircraft’s acceleration, as both are affected by the same gravity and acceleration forces, in which the longitudinal stability of the aircraft must be ensured immediately upon takeoff. An inverted pendulum and a UAV aircraft system simulation were developed with basic MATLAB software. The inverted pendulum simulation showed that as the value of the spring’s stiffness at the limit of stability (klim) increased, the system became more convergent and, as a result, more stable. The stiffness of the spring at the limit of stability, klim = 32.69 N m-1 (i.e., equivalent to an initial angular rotation θ = 5 °), and the system’s stability were observed up to the value of klim = 179.79 N m-1, which resulted in an unstable short initial period. In addition, for the aircraft’s wing, the damping coefficient (clim) value was in the range of clim ≥ 10,000 N s m-1. Therefore, with the damping ratio ζ being equal to zero, the system vibrated consistently at its natural frequency (wn), never deviating drastically to become unstable.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"21 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138976339","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 experiment was carried out at the Horticulture Department of the Universidad Autónoma Agraria Antonio Narro. Tuberous roots of four D. pinnata varieties were sown directly into the soil and covered with mulch. The shade netting production environment proved to be the best in production, with the best results in plant height, stem diameter, number of leaves, and days to flowering. The highest-performing cultivar was the Antje variety. On the other hand, the Antje variety (cultivated under shade netting) had the longest flower stalks, the Boy Mick variety (cultivated in the greenhouse) had the heaviest flowers, and the Canby Centennial variety (cultivated in open field) had the flowers with the thickest stalks. The results show that Dahlias can be grown in northeastern Mexico because the area meets suitable conditions for crop development and production.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"25 10","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138587830","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 results revealed that approximately 90 % of the participants have a positive perception of GWs and GRs. The psychological and environmental benefits of greening in urban environments are recognized, such as creating habitats for small species, reducing stress, and improving mood, among others. Some significant differences were seen in some socioeconomic aspects, such as age, gender and educational level. Women showed a tendency to find calm when in contact with plants, while the tendency for men is more neutral. Participants with a lower educational level, secondary school and a technical career, do not fully agree that nature positively affects their mood.

The objective of the research was to analyze the distribution and spatial association of fumagina and green scale in the coffee crop in Sultepec, State of Mexico, Mexico. During the first semester of 2022, random coffee plots were marked and geo-referenced for sampling. Several methods were used to obtain the spatial distribution of fumagina and green scale. The results showed fits of Gaussian, exponential, and mostly spherical geostatistical models, which represent an aggregate distribution and an association of these problems with each other. The estimation of the infested and infected area for both problems was obtained using the ordinary kriging method, revealing the presence of foci of infection and infestation. In plot three, it was identified that these are maintained and increase as the sampling progresses, finding a high degree of dependence and spatial stability. It is concluded that the populations of green scale and fumagina have an r value of 0.70, indicating a high association and correlation between them, which leads to a spatial distribution and possible management of targeted control of these phytosanitary problems and, in turn, sustainable management of the crop.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"156 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135371830","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}

Traditionally, plantation monitoring has been done manually; however, having accurate information on agave inventories is crucial for planning and estimating production volume. In this context, it was proposed that deep learning algorithms can achieve high detection rates of agave plants, improving the management and control of plantations. For this purpose, YOLOv4 and YOLOv4-tiny convolutional algorithms were implemented and evaluated using high-resolution RGB aerial images captured by a remotely piloted aircraft system for the determination of agave plant density. Three flight plans were planned and carried out, with ground sampling distances of 1.10, 1.64, and 2.19 cm pixel-1, respectively. The database was created, and the algorithms were evaluated for a confidence level of 0.25 and an intersection threshold over the junction of 0.50. The results showed an average mean accuracy of 0.99 for both algorithms and an F1 score of 0.95 for YOLOv4 and 0.96 for YOLOv4-tiny. Furthermore, a high detection rate (Rc) of 99 % and precision values (Pr) between 90 and 92 % were obtained. A decrease in the performance of the algorithms was observed when detecting agave tillers in images with a spatial resolution of 2.19 cm pixel-1. The implemented YOLO convolutional algorithms proved to be highly robust and able to generalize agave plant characteristics at different phenological stages, allowing accurate detections. In addition, the coordinates of the detected plants were used to estimate the distance between them, with a maximum error of 20 cm.","PeriodicalId":50836,"journal":{"name":"Agrociencia","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134907494","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}
