The cultivar RS Centenário is the result of a selection carried out in 2007 using the “Iraí” cultivar, in a plot of genetic seed production.

After two advancing generations, the phenotypic uniformity of the population was reached and the seeds were harvested in bulk. After several tests, the “SM 0112” lineage was denominated cultivar “RS Centenário” and the results of the assessed at a value for cultivation and use (VCU) trials were used to register the new cultivar. “RS Centenário” was registered as a new cultivar to be commercially grown in the Rio Grande do Sul state (RS), in southern Brazil. “RS Centenário” is a common bean (Phaseolus vulgaris L.) cultivar with a brindle seed coat, average weight of 1,000 seeds of 343 g, erect plants, indeterminate growth habit II/III, cycle of 88 days, high added value and average yield of 1,685 kg ha-1.","PeriodicalId":33658,"journal":{"name":"Pesquisa Agropecuaria Gaucha","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135825406","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}

The study took place at the Centro Estadual de Diagnóstico e Pesquisa Florestal, Santa Maria, RS, Brazil. We collected plant samples from the periphery and cultivated kale plants at three distances from the edge: within two meters, 10 to 12 meters, and 20 to 22 meters. We recorded the number and biomass of marketable leaves from three harvests. A total of 618 arthropods were collected from plants along the periphery: Insecta (589), Arachnida (20), and Entognatha (9). Hemiptera was the most prevalent order (49.84%). Kale plants near the periphery experienced less predation from leaf beetles. Plants along the periphery hosted important predator groups as well as phytophages that can serve as alternative prey. Diversifying the periphery with fennel, fava bean, and marigolds shows promise as a strategy to enhance the arthropod community in kale cultivation, thereby acting as a conservative biological control.","PeriodicalId":33658,"journal":{"name":"Pesquisa Agropecuaria Gaucha","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46078668","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}

Located in the south of the state, these areas have different edaphoclimatic conditions from those existing in the Serra Gaúcha, traditional production region. Thus, the estimation of reference values for leaf nutrient contents specific for the conditions of the Campanha is essential for the correct management of vineyards. Methods such as Mathematical Chance (MCh) enable the determination of sufficiency levels of leaf nutrients by evaluating commercial production areas. This work aimed to estimate reference values for nutrients in leaf tissue of grapevines in the region of Campanha by using the MCh method. Nutritional sufficiency ranges differed from those estimated by the official research for the state. However, they revealed high similarity with the results obtained by other studies carried out in the Campanha Region by using DRIS and CND approaches. Our results demonstrated that the MCh was able to estimate the infra- and supra-optimal limits, as well as the optimal levels for nutrients, indicating that there is potential for foliar diagnosis of vineyards in RS to be performed based on regionalized parameters.","PeriodicalId":33658,"journal":{"name":"Pesquisa Agropecuaria Gaucha","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43512082","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}

The temperature-humidity index (THI) is one of the most used indicators to evaluate thermal comfort levels. This work aimed to evaluate the levels of thermal comfort for bovine dairy production in Rio Grande do Sul state through the THI calculation and its impact on milk production, considering daily yields of 15 kg and 30 kg per cow. The THI values and decrease in milk yield were calculated using data between 1990 and 2021 from the National Institute of Meteorology (INMET). The observed results considering the average temperatures showed that conditions of thermal discomfort occur only in summer, intensifying in January. Milk production was most affected in the western border region of the state, corresponding in parts to the physiographic regions of Alto Uruguai, Missões, and Campanha, which have a warmer climate. The climate classification proposed by Maluf had the best spatial correspondence with the ITU. This classification may be used in the evaluation of places with greater suitability for dairy farming in the state and to indicate places where it is necessary to implement action to mitigate the effects of thermal discomfort in dairy cattle.","PeriodicalId":33658,"journal":{"name":"Pesquisa Agropecuaria Gaucha","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49608440","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}

Results indicated that if the objective is to seek short intervals between grazing, associated with higher forage quality, the 60 x 25, 60 x 40 and 80 x 40 managements are the most indicated ones. For maximum forage productivity, 80 x 10 and 80 x 25 are the most recommended ones.

The main methods of synthesis are the chemical and the biogenic pathway, or green, which is less environmentally polluting, more environmentally friendly, and simpler, although standardization is more complex. Morphological and physical-chemical characteristics differ according to the synthesis method and, consequently, present different degrees of toxicity. Nanotoxicology studies the toxicity of nanoparticles on living organisms and scientists seek to know about the physical-chemical properties and their influence on interaction with the environment. It is known that there are several parameters that influence toxicity, such as dose, particle size, shape, morphology, surface chemistry, agglomeration/aggregation state, synthesis method, cell type and organism in which it is tested.
