Resumo: | The presence of toxic aluminum in the soil and N deficiency are one of the main causes of degradation of cultivated pastures, mainly of the Urochloa genus. The use of agricultural gypsum for restoring soil fertility is one of the ways to recover the productive capacity of degraded areas. Given the above, the work aims to assess pasture recovery with the application of agricultural gypsum associated with nitrogen fertilization. The experimental design was randomized blocks in a 3x4 factorial arrangement, that is, absence of nitrogen, 50 kg ha-1 in the form of ammonium nitrate and 50 kg ha-1 urea, interacting with four doses of agricultural gypsum, namely: 0 ; 750; 1500 and 3000 kg ha-1 and with four replications, totaling 48 plots. The use of urea as a source of N resulted in a higher plant height (PH) when compared to the use of ammonium nitrate, representing a relative increase of approximately 12% in relation to the control. Dose of 1730.8 kg ha-1 of agricultural gypsum resulted in a maximum production of 4.97 t ha-1 of dry pasture. The linear interaction of the use of ammonium nitrate with gypsum doses shows an extremely interesting synergistic potential with this source. For dry mass of culms (CDM), the use of urea had a PMTE of 1730.8 kg ha-1 of agricultural gypsum resulting in 2.38 t ha-1. The culms dry mass of (CDM) represented 47.9% of the total dry mass of the pasture. |

La corrección con yeso y la reconstitución de la fertilidad del suelo es una de las formas de recuperar la capacidad productiva de los pastos degradados. El objetivo de este trabajo fue recuperar un área de pasto con la aplicación de yeso agrícola asociado a la fertilización nitrogenada. Se realizó un experimento en bloques al azar en un esquema factorial 4x3, involucrando cuatro dosis de yeso agrícola, asociado o no a fertilización nitrogenada con 50 kg ha-1 en forma de nitrato de amonio o urea; con cuatro repeticiones, totalizando 48 parcelas. Las parcelas tenían 25,0 m2. El uso de urea como fuente de N resultó en una mayor altura de planta (PH) en comparación con el uso de nitrato de amonio, lo que representa un aumento relativo de aproximadamente 12% en relación al testigo. El punto de máxima eficiencia técnica (PMTE) para la masa seca total (TDM) fue con el uso de urea. La dosis de 1730,8 kg ha-1 de yeso agrícola resultó en una producción máxima de 4,97 t ha-1 de materia seca de pastos. La interacción lineal del uso de nitrato de amonio con dosis de yeso denota un potencial sinérgico extremadamente interesante con esta fuente. Para la masa seca de culmos (CDM), el uso de urea tuvo un PMTE de 1730.7 resultando en 2.38 t ha-1. La dosis máxima para esta variable corrobora la masa seca total (TDM). La masa seca de los culmos (CDM) representa el 47,9% de la masa seca total del pasto.A presença de alumínio tóxico no solo e deficiência de N são uma das principais causas de degradação de pastagens cultivadas, principalmente do gênero Urochloa. A correção com gessagem e reconstituição da fertilidade do solo é um dos caminhos para recuperar a capacidade produtiva das pastagens degradadas. O objetivo desse trabalho foi à recuperação de uma área de pastagem com a aplicação do gesso agrícola associado à adubação nitrogenada. Foi instalado um experimento em blocos casualizados em esquema fatorial 4x3, envolvendo quatro doses de gesso agrícola, associadas ou não com adubação nitrogenada com 50 kg ha-1 na forma de nitrato de amônio ou ureia; com quatro repetições, totalizando 48 parcelas. As parcelas tiveram 25,0 m2. A utilização de ureia como fonte de N resultou uma plant height (PH) superior quando comparado ao uso de nitrato de amônio, representando um incremento relativo de aproximadamente 12% em relação à testemunha. O ponto de eficiência técnica (PMTE) para a massa seca total (TDM) foi com o uso da ureia. Dose de 1730,8 kg ha-1 de gesso agrícola acarretou na produção máxima de 4,97 t ha-1 de matéria seca de pastagem. A interação linear do uso de nitrato de amônio com doses de gesso denota um potencial sinérgico extremamente interessante com essa fonte. Para a massa seca de colmos (CDM), o uso de ureia teve um PMTE de 1730,7 resultando em 2,38 t ha-1. A dose máxima para essa variável corrobora com a massa seca total (TDM). E a massa seca de colmos (CDM) representa 47,9% do total de massa seca da pastagem.Research, Society and Development2020-09-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/798110.33448/rsd-v9i9.7981Research, Society and Development; Vol. 9 No. 9; e913997981Research, Society and Development; Vol. 9 Núm. 9; e913997981Research, Society and Development; v. 9 n. 9; e9139979812525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/7981/7190Copyright (c) 2020 Gabriel Banos Rodrigues; Lucas Aparecido Manzani Lisboa; Samira Rangel do Prado Frade; Luciano Flávio Neves Ramos; Bianca Pereira Franco de Souza; Mateus Xavier de Alencar; Gabriel Geminiano da Silva; Leandro Aparecido Fogagnoli Contierohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRodrigues, Gabriel Banos Aparecido Manzani Lisboa, LucasFrade, Samira Rangel do Prado Ramos, Luciano Flávio Neves Souza, Bianca Pereira Franco de Alencar, Mateus Xavier de Silva, Gabriel Geminiano da Contiero, Leandro Aparecido Fogagnoli 2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7981Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:33.865532Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
