Objetivou-se avaliar diferentes substâncias utilizadas no condicionamento fisiológico de sementes de milho para a superação de estresses abióticos no momento da germinação e emergência. O delineamento experimental foi inteiramente casualizado em esquema fatorial 2 x 5, sendo constituído de dois lotes de sementes, e quatro agentes químicos utilizados no condicionamento fisiológico, mais a testemunha. As sementes foram submetidas a diferentes estresse abióticos: baixa temperatura, hipóxia, estresse salino e restrição hídrica. O condicionamento fisiológico de sementes através da imersão direta, no período de 18 horas e com ambas as substâncias se mostrou de modo geral, um método promissor para superar efeitos deletérios abióticos encontrados a campo no momento da germinação. A utilização de nitratos via condicionamento fisiológico é uma alternativa para promover efeitos benéficos perante a situações de estresse. O condicionamento fisiológico proporciona maior velocidade de emergência, independente da substância utilizada, sem interferir no desenvolvimento inicial de plântulas.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42974329","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}

O objetivo deste trabalho foi avaliar o efeito da adubação nitrogenada e manejos das forrageiras tropicais nas propriedades físicas do solo. O experimento foi realizado entre outubro de 2017 e janeiro de 2020, em Marechal Cândido Rondon – PR, em blocos ao acaso, com parcelas sub-subdivididas com uma testemunha adicional e quatro repetições. As parcelas foram constituídas por duas espécies forrageiras consorciadas com o milho: Urochloa brizantha e Magathyrsus maximum, mais a testemunha adicional (milho solteiro). As subparcelas consistiram nos manejos das forrageiras: fenação e pastejo; e nas sub-subparcelas, a presença ou ausência de adubação nitrogenada. Foram determinadas: densidade do solo (Ds), porosidade total (Pt), macro (Ma) e microporosidade (Mi), além da resistência do solo à penetração (Rp). A utilização de nitrogênio (N) em cobertura nas forrageiras após os manejos, aumentou a quantidade de Ma na camada de 0-0,05 m para o primeiro ano. Os valores de Ds estão acima do limite considerado crítico para o desenvolvimento das plantas, porém, com tendência à redução. A adoção do SIPA, independente da espécie forrageira utilizada e manejo adotado, seja fenação ou pastejo, não comprometeu a qualidade física do solo, sendo assim, uma ótima alternativa para a diversificação da produção na propriedade.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48663915","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}

Thus, this study evaluates the potential of the essential oils of Cedrela fissilis and Mentha spicata in the in vitro control of the mycelial growth of the pathogen Corynespora cassiicola. The experiment was conducted at the Phytosanitary Laboratory of the Universidade Estadual do Mato Grosso do Sul (UEMS), University Unit of Cassilândia-MS. The essential oils of Argentine Cedar (Cedrela fissilis) and Spearmint (Mentha spicata) were acquired from commerce. A completely randomized design was used with a factorial scheme of two categories of essential oils (Spearmint and Cedar) x 5 concentrations (0, 25, 50, 100, and 200 μL L 1 ). The data were submitted to the analysis of variance. The means were compared by the Tukey test at 5% probability. Quantitative data were submitted to regression analysis. The fungicide effect was determined by measuring the diameter of colonies (mean of two diametrically opposed measurements, using a caliper, every 72 hours until reaching 216 hours). Spearmint essential oil (M. Spicata) presented higher efficiency than Argentine Cedar essential oil (Cedrela fissilis) on reducing of Corynespora cassiicola growth in the periods between 72 and 144 hours in vitro.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42872311","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 objective of this work was to analyze the decomposition of straw remaining from autumn/winter crops in the development of soybean in succession in the Midwest region of Paraná. The experiment was conducted between 2019 and 2021 in a completely randomized design, with eight treatments (spontaneous, black oat, brachiaria, corn, wheat, oilseed radish, corn + brachiaria, and black oat + oilseed radish) and four replications. After autumn/winter cultivation, biomass samples were dried and placed in nylon bags, returning to the original plot during soybean sowing. The decomposition bags were collected in seven periods over 120 days, coinciding with the soybean cycle. The decomposition rate was analyzed by regression. The regression equations and the amount of biomass remaining from the autumn/winter seasons were determinate the half-file and the remaining mass on the soil surface at sowing and at 30, 60, 90, and 120 days after sowing. Biomass production and decomposition rate varied with the season, depending on environmental conditions. Wheat had the lowest decomposition rate with a half-life greater than 100 days.

In this sense, the objective was to analyze the growth and productivity of Biquinho pepper (Capsicum chinese) plants cultivated in two types of protected environments and benches with reflective material. The experiment was conducted in a completely randomized design, with five repetitions. A plastic greenhouse with 42% shading and agricultural screen with 30% shading, inside these environments, there were benches with and without reflective material of the type Aluminet® with 50% shading. The plastic greenhouse presented lower temperature and relative air moisture, besides lower global solar radiation and photosynthetically active radiation. The benches with reflective material, independently of the environment, have promoted higher photosynthetic reflected radiation. Plants produced in the greenhouse had larger sizes, diameters, and leaves in their initial growth stage. As of 56 DAT, the plants in the agricultural screen presented greater heights and promoted greater pepper production. The reflective benches have favored the growth in diameter and at 14 and 28 DAT, and greater fruit production. It is concluded that the agricultural screen with 30% shading and reflective benches favor the Biquinho pepper fruit production.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41618442","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 experiments were carried out in two periods during the 2014/2015 growing season at the Experimental Farm of Gurupi belonging to the Federal University of Tocantins, using the variety BRS Novaera. Inoculation was carried out with a standard strain recommended for cowpea. The experimental designs were randomized in blocks in a 2×6 factorial arrangement, with the first factor consisting of the inoculation (presence and absence) and the second factor consisting of six phosphorus doses (0, 30, 60, 90, 120, and 150 kg ha−1 of P2O5), totaling 12 treatments with four replications. Total chlorophyll, leaf P content, flowering, hundred-grain weight, and yield were evaluated. Phosphorus fertilization had a positive influence on the total chlorophyll, flowering, and leaf P content of cowpea on the Oxisol in the Cerrado region of Tocantins. The application of 113.42 kg ha−1 of P2O5 provided a yield of 1,124 kg ha−1 in the first planting period, corresponding to an 83% increase. However, phosphorus fertilization and inoculation increased grain yield in the second period, with the maximum yield reaching 145.94 kg ha−1, obtained with the maximum effect dose of 123.04 kg ha−1 of P2O5, with a yield gain of 257.3%.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49112677","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}
