Resumo: | Grasslands in southern Brazil have inherent characteristics favorable to forage production for domestic herbivores, which can be impaired or enhanced by management. The aim of this study was to evaluate the influence of management on plant characteristics, comparing commonly used techniques. The experimental design was bifactorial, the first factor consisting of four managements: burning, oversowing with annual winter forages, mowing and absence of interference, and the second factor was the time elapsed between management and evaluation. The experiment was conducted under field conditions, in a complete randomized block design with four replications. The LAI (leaf area index), dry mass production and crude protein content of the pasture were evaluated. Pasture management with oversowing showed higher LAI growth rate, as well as higher pasture dry mass production than the other treatments. There was no effect of the different managements on the crude protein content of the pasture, but of the time, with the highest value on the 53rd day. The results suggest that the adoption of management with oversowing of annual winter forages should be emphasized for the productive improvement of native grasslands in southern Brazil. |

El objetivo de este estudio fue evaluar la influencia del manejo sobre las características de las plantas, comparando técnicas comúnmente utilizadas. El diseño experimental fue bifactorial, constando el primer factor de cuatro manejos: quema, sobresiembra con forrajes anuales de invierno, siega y ausencia de interferencia, y el segundo factor fue el tiempo transcurrido entre el manejo y la evaluación. El experimento se realizó en condiciones de campo, en un diseño de bloques completos al azar con cuatro repeticiones. Se evaluó el IAF (índice de área foliar), la producción de masa seca y el contenido de proteína cruda del pasto. El manejo del pasto con resiembra mostró una mayor tasa de crecimiento de IAF, así como una mayor producción de masa seca del pasto que los otros tratamientos. No hubo efecto de los diferentes manejos sobre el contenido de proteína bruta de la pradera, pero sí del tiempo, con el mayor valor en el día 53. Los resultados sugieren que se debe enfatizar la adopción de manejo con resiembra de forrajes anuales de invierno para la mejora productiva de los pastizales nativos en el sur de Brasil.Os campos do Sul do Brasil possuem características inerentes favoráveis à produção de forragem para herbívoros domésticos, que podem ser prejudicadas ou potencializadas pelo manejo. O objetivo do trabalho foi avaliar a influência do manejo nas características das plantas, comparando técnicas comumente utilizadas. O delineamento experimental foi bifatorial, sendo o primeiro fator composto por quatro manejos: queimada, sobresemeadura com forrageiras anuais de inverno, roçada e ausência de interferência, e o segundo fator foi o tempo decorrido entre manejo e avaliação. O experimento foi conduzido em condições de campo, em delineamento em blocos completos casualizados com quatro repetições. Foram avaliados o IAF (índice de área foliar), produção de massa seca e teor de proteína bruta da pastagem. O manejo da pastagem com sobressemeadura apresentou maior velocidade de crescimento do IAF, bem como maior produção de massa seca da pastagem que os demais tratamentos. Não houve efeito dos diferentes manejos sobre o teor de proteína bruta da pastagem, mas sim do tempo, com o maior valor no 53° dia. Os resultados sugerem que a sobressemeadura de forrageiras anuais de inverno deve ser enfatizada para a melhoria produtiva dos campos nativos do Sul do Brasil.Editora Verde2023-02-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/955110.18378/rvads.v18i1.9551Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 18 No. 1 (2023); 24-28Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 18 Núm. 1 (2023); 24-28Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 18 n. 1 (2023); 24-281981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAenghttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/9551/11380Copyright (c) 2023 Luigildo Proner Junior et al.https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessProner Junior, LuigildoBittencourt, Henrique von HertwigDias, Juliano CesarSilveira, André Luís Finkler daBonome, Lisandro Tomas da Silva2023-03-10T11:44:25Zoai:ojs.gvaa.com.br:article/9551Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:49.591842Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
