Thus, the biological control using fungus is an effective tool in the integrated diseases management. This study aimed to evaluate the compatibility of fungicides Certeza, Apron and Vitavax on the microorganisms Trichoderma asperelloides and Azospirillum brasilense. The experiments were conducted in vitro in a completely randomized design with a factorial arrangement 2 x 3 with three replications. The first factor composed of two doses and the second referred to the fungicides. The microorganisms were developed in PDA medium. After the medium has solidified, in a flow layer 10 µL of the fungal solution was added to each plate with the aid of an automatic pipette (D1, recommended dose; D2, double of recommended dose). Then, each Petri plate was centrally inoculated with a disc of Trichoderma asperelloides, in addition to the uninoculated control. For Azospirillum brasilense, the colony surface was scraped with the aid of a sterilized Drigalsky loop. Then, the filter of discs paper was dipped in the fungicides solution and placed on the medium surface. After this process, the plates were incubated in a BOD (Biochemical Oxygen Demand) at 26±2ºC and photoperiod 12 h. The parameters evaluated were a mycelial growth and sporulation. The results showed that there was no significant interaction between the factors. The fungicides Certeza (Tiofanato metílico + Fluazinam), Apron (Fludioxonil + Metalaxil-M) and Vitavax (Carboxina + Tiram) are considered compatible with Trichoderma asperelloides and Azospirillum brasilense. The fungicides can be used in an integrated disease management practices, priority must be given to use the products that have been shown to be less harmful.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47530344","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 present work aimed to evaluate the effect of light intensity and exogenous application of gibberellin on seedlings of four ornamental species (Calendula officinalis, Gypsophila elegans, Solenostemon scutellarioides and Viola wittrockiana). The experiment was carried out at the Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos. The seeds were sown in trays containing substrate composed of a mixture of humic Distroferric Red Latosol: medium texture sand: commercial substrate, in the volumetric proportion of 2:1:1, respectively. The trays were kept in shading environments, using black screens with 35%, 50% and 80% shading intensity, red with 35% shading, in addition to full sun. After 30 days of emergence, gibberellic acid solution was applied to the seedlings at concentrations of 0 mg L-1 and 300 mg L-1. Emergence, emergence speed index, mean emergence time, total length, shoot and roots, number of leaves, leaf area, root volume density, shoot, root and total dry matter were evaluated. For each environmental condition of cultivation, the values of temperature and air humidity and light intensity were obtained. The use of gibberellic acid proved to be beneficial for Viola wittrockiana and Solenostemon scutellarioides. The shading environments, regardless of color and light intensity, were more favorable for the formation of seedlings of these four ornamental species.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47339520","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 experiment was carried out in a protected environment with a randomized block design in a 2 x 3 x 3 factorial scheme containing 2 treatments consisting of two basil cultivars (alfavaca basilicão, red and green) and fifteen replications. The first factor was constituted by the cultivars, the second, by the time of collection, and the third, by the positions in which the collections were carried out on the plant. For evaluations of morphometric variables and gas exchange rates, the two cultivars were compared. Basil has photosynthesis saturation at radiation rates of about 1500 μmol m-2 s-1. The green colored cultivar was more productive, in addition to having the highest levels of chlorophyll a, b and total, and lower rate of leaf transpiration in response to photosynthetically active photons flow density, adapted for greater carboxylation efficiency and water use.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46651998","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}

Therefore, the objective of this work was to emphasize the importance of physical and chemical changes in the soil of pastures under crop-livestock-forest integration in general and in the Amazon region of state of Maranhão, Brazil. Therefore, a literature review was conducted through a search for studies in the Google Scholar database, which encompasses multiple other databases, such as Scielo, Elsevier, Scopus, Capes, and others. In face of the conditions of degradation in pastures throughout the state of Maranhão and the broad distribution of native forests such as Babassu forests, the use of technology from CLFI systems could allow for their recovery and sustainable status by means of economically and ecologically feasible productivity.

The selected crops were those of coconut, mango and grape, between the years 2001 to 2018; literacy rate and level of education in Brazil and the northeast region, the relationship between male and female genders, percentage of women in formal jobs in the years 2004 to 2015 and average monthly income in Brazil and the Northeast region and male and female genders in the years 2012 to 2015. There was a reduction in the area cultivated with coconut, however there was no increase in the area for mango and grape crops. Regarding the harvested area, the coconut crop showed a larger cultivated area, however, this area has been gradually reduced. In mango and grape crops, no variations were detected in the harvested areas. As for the average production, the grape crop has higher productivity. In the percentage of formal jobs, literacy and level of education of women, both nationally and regionally, there was a linear growth and higher than those of men.

The experimental design was in randomized blocks, in a factorial 2×3 [2 black oat pasture residual heights (15 and 7 cm), under rotational grazing × 3 nitrogen rates applied to pasture (0, 75 and 150 kg N ha-1)], with 4 repetitions. Soil PR was measured using an electronic penetrograph to an 80 cm depth. Soil samples were collected to determine gravimetric moisture. In the first year, 75 kg N ha-1 resulted in the highest depth compaction while intensive grazing (7 cm) resulted in the highest PR. In the second year, plots without N resulted in lower PR levels, mainly in the superficial layers. However, the rate of 150 kg N ha-1 presented greater compaction in the 15-20 cm layer after grazing. The high moisture levels in depth reduced PR in all evaluated periods, highlighting the close relationship between both variables. General grazing heights did not affect PR, but the use of systems that increase residues production, as moderate grazing and nitrogen fertilization might be an alternative to mitigate the soil compaction in surface layers effects.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45370216","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 recent years, rural producers have manufactured microorganisms on their properties for direct application in crops, a practice known as on farm production. In this work of literature review, aspects related to the home production of microorganisms, advantages, disadvantages and future perspectives are addressed. The practice is not illegal. Producers are supported by the Organic Law, which allows the production of agricultural inputs for their own use. One of the main advantages of homemade multiplication is the reduction in the cost of purchasing the products and the inexistence of transport and storage costs. Quality control is essential for using the technique, as the main risk is contamination with human and animal pathogens. The main multiplied microorganisms are: Trichoderma sp., Metarhizium anisopliae, Bacillus subtilis, B. pumilus, B. amyloliquefaciens, B. thuringiensis, Bauveria bassiana, Nomuraea riley and Azospirillum brasilense. These microorganisms act in the induction of resistance, parasitism, antagonism and the production of enzymes that degrade the cell wall, as well as the production of toxic substances, essential characteristics for the alternative control of pests and diseases. On farm production is driven by the demand for healthier foods, the occurrence of chemical resistance problems and the lack of new products, traditionally used in conventional agriculture.","PeriodicalId":30289,"journal":{"name":"Scientia Agraria Paranaensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42753753","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}
