Resumo: | The rice is a cereal present in the daily Brazilian basic nutrition which, the demand grows as population increases. Upland rice is a kind of agricultural crop that it has gained space because it is able to use and to recover soils of areas while to ensure income to producers and it supply the demand for the grain. Therefore, technologies are necessary to increase the yield in upland rice, which are more sustainable and which can reduce the cost of production in agricultural areas. The objective of work was to evaluate the seed inoculation of rice with Azospirillum brasilense associated with doses of recommended nitrogen fertilization doses in sowing and topdressing (0, 50 e 100%). The experimental design was randomized blocks with four replications. The study was developed in the 2013/14 season in a typical dystrophic Red Latosol (Oxisol), in Selvíria - MS. The presence of 100% of the recommended N dose reduced the hectolitric mass of grains. The inoculation with A. brasilense + 50% of the recommended N dose and, absence of inoculation + 100% of the recommended N dose provided increase in the number of panicles m-2. The inoculation with A. brasilense associated or not to the fertilization with 50% of the recommended N dose fostered gains in yield of upland rice. |

También es una cultura que, en el régimen de secano, ganó espacio para el aprovechamiento y recuperación de espacios. Por lo tanto, puede garantizar la rentabilidad al productor y complementar la demanda del grano en el mercado. En vista de los sistemas de producción sustentables que impulsan la productividad del arroz, la inoculación de semillas con Azospirillum puede ser una alternativa ya que aumenta la superficie de agua, la absorción nutricional y el aporte de N vía fijación biológica de nitrógeno, además de generar ahorros para el productor al reducir el uso de insumos minerales. El objetivo del trabajo fue evaluar el efecto de la inoculación de semillas de arroz con Azospirillum brasilense asociado a dosis de fertilización nitrogenada en siembra y cobertura recomendada (0, 50 y 100%). Se utilizó un diseño de bloques al azar con cinco repeticiones. El estudio se realizó en el año agrícola 2012/13 en un típico RED LATOSOL arcilloso distrófico, en Selvíria - MS. La presencia del 100% de la dosis de N redujo la masa hectolitrica de granos. La inoculación con A. brasilense + 50% de la dosis de N y la ausencia de inoculación + 100% de la dosis de N proporcionaron un aumento en el número de panículas m-². La inoculación con A. brasilense asociada o no a la fertilización con 50% de la dosis de N aumentó la productividad del arroz de secano.O arroz é um cereal presente na alimentação básica diária brasileira, cuja demanda tem sido maior à medida do aumento populacional. Também é uma cultura que, no regime de terras altas, ganhou espaço por possibilitar aproveitamento e recuperação de áreas. Portanto, pode garantir rentabilidade ao produtor e complementar a demanda pelo grão no mercado. Tendo em vista sistemas de produção sustentáveis e que impulsionam a produtividade do arroz, a inoculação de sementes com Azospirillum pode ser uma alternativa visto que aumenta a superfície de absorção hídrica, nutricional e fornecimento de N via fixação biológica de nitrogênio, além de gerar economia ao produtor pela redução do uso de insumos minerais. Assim, o objetivo do trabalho foi avaliar o efeito da inoculação de sementes de arroz com Azospirillum brasilense associada a doses de adubação nitrogenada em semeadura e cobertura recomendadas (0, 50 e 100%). Utilizou-se o delineamento experimental em blocos casualizados com cinco repetições. O estudo foi desenvolvido no ano agrícola de 2012/13 em um LATOSSOLO VERMELHO Distrófico típico argiloso, em Selvíria – MS. A presença de 100% da dose de N reduziu a massa hectolítrica de grãos. A inoculação com A. brasilense + 50% da dose de N e, ausência de inoculação + 100% da dose de N proporcionaram incremento no número de panículas m-². A inoculação com A. brasilense associada ou não à adubação com 50% da dose de N incrementou a produtividade do arroz de terras altas.Research, Society and Development2021-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1634510.33448/rsd-v10i7.16345Research, Society and Development; Vol. 10 No. 7; e9110716345Research, Society and Development; Vol. 10 Núm. 7; e9110716345Research, Society and Development; v. 10 n. 7; e91107163452525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16345/14570Copyright (c) 2021 Letícia Zylmennith de Souza Sales; Nayara Fernanda Siviero Garcia; Juliana Trindade Martins ; Fernando de Souza Buzo; Lucas Martins Garé; Ricardo Antonio Ferreira Rodrigues; Orivaldo Arfhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSales, Letícia Zylmennith de Souza Garcia, Nayara Fernanda SivieroMartins , Juliana TrindadeBuzo, Fernando de SouzaGaré, Lucas Martins Rodrigues, Ricardo Antonio Ferreira Arf, Orivaldo2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16345Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:54.878038Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
