Five strains were identified as B. pumillus (B32), B. thuringiensis (B116), B. megaterium (B119) and B. subitilis (B2082 and B2084) using 16S rRNA gene sequencing and MALDI-TOF mass spectrometry. Repetitive element palindromic (Rep-PCR) and amplified ribosomal DNA restriction analysis (ARDRA) techniques allowed the discrimination of the strains, except B2082 and B2084 that presented identical genetic profiles, indicating that they are same or genetically close isolates. Moreover, specific molecular markers were developed for B116 and B119 strains and may be used for microbial inoculants production quality control, strains traceability and to detail PGPB colonization.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47653617","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 aim of the study was to verify the evolution and identify the structure, spatial dynamics and transformation of maize and soybean production systems in the state of Paraná. Municipal Agricultural Production data from the Brazilian Institute of Geography and Statistics (IBGE) provided the basis for this study. The Location Quotient was analyzed to identify microregions specialized in the production of soybean and first and second crops of maize. Principal components and groups were analyzed in order to characterize the structure and dynamics of maize and soybean production systems in specialized microregions. The results show how maize and soybean production systems have been transformed; soybean is now cropped in areas previously occupied by first crop maize, and the area occupied by second crop maize has increased. This has led to the predominant use of the crop rotation system with first crop soybean followed by second crop maize.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47727162","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}

Experimental randomized block design was used, with four replications. The forage species were evaluated as to dry matter production, chemical-bromatological composition, estimated milk production (kg ha-1) and gross income (R$ ha-1). Maize was cultivated in succession, with doses of 0, 100 and 200 kg of N ha-1, in a split-plot design. Among the profitability indices evaluated, the gross margin (R$ ha-1) stands outs. The data were submitted to analysis of variance and the means were compared through Tukey's test at 5% probability. In the pasture phase, the Bo+N treatment presented higher gross income. In the cropping phase, the gross margin was higher in the Bo+Ve treatment, but it did not differ from the Bo+N treatment.

The direct application of rock phosphate (RP) and the inoculation with phosphate solubilizing bacteria (PSB) is a sustainable alternative for P supply to the crops. The aim of this study was to evaluate the effect of PSB inoculation of two sorghum genotypes with different P responses (BR007 - efficient and responsive and SC283 - efficient and non-responsive), cultivated in soil fertilized with RP and triple superphosphate (TSP), in greenhouse and field experiments. The sorghum genotypes were inoculated separately with the Bacillus strains that are efficient in P solubilization, B116 and B70, and cultivated under different P fertilization sources (TSP, RP, ½TSP + ½RP). The results suggest that the inoculation response was dependent on sorghum genotype, P source and microbial strain. Inoculation of the genotype BR007 significantly increased root biomass and grain P content under greenhouse conditions, as well as yield and grain P content in field experiments, but no effect was observed on genotype SC283. The use of PSB as bioinoculants, in combination with RP, is a promising alternative to reduce the use of synthetic fertilizers, contributing to the sustainable sorghum production.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47019416","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}

Two experiments were conducted in the experimental lowland area of the Federal University of Santa Maria – UFSM, during the 2014/15 crop season. The experiments consisted in the use of implantation systems with and without raised seedbeds and surface irrigation. The evaluated characteristics were plant height, shoot dry mass, leaf area index, yield components and grain yield. Plant height, leaf area index and shoot dry mass are higher when maize is grown in raised seedbeds in lowland areas. The raised seedbed system can be considered an efficient way to improve drainage in the cultivation area, resulting in a higher grain yield. The use of irrigation during periods of water deficit, in the critical period of crop growth, increases the grain yield of maize grown in lowland areas.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45266600","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}

To increase knowledge about the control of this pest in organic and conventional maize crop, tests were conducted to verify if the duration of pupae availability in days, the type of crop treatment (organic and conventional), the stage of crop development, and the depth of the soil significantly affect predation by natural enemies. The pupaeavailability time (days) in the soil did not affect their removal by natural enemies. However, in the fallow stage, on the surface and in the reproductive phase, the predation was higher. In organic maize, predation was 15% higher when compared to conventional maize. The rupture of the soil and the possible losses associated with beneficial fauna were the main factors responsible for higher predation during fallow, so conservationist practices usually used in organic treatment are the main reason for higher predation in this type of crop. There is a significant decrease in the control of H. armigera pests by natural enemies when maize is grown using conventional practices, what reinforces the importance of the conservation techniques used in maize crops.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41523499","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}
