Resumo: | Forage sorghum is a plant with high potential for the Brazilian Midwest, especially because it is considered tolerant to adverse conditions and the high capacity of tillering and regrowth of the ratoons after being cut for silage. The objective of this work was to evaluate the influence of nitrogen (N) doses and cutting management on yield of the forage sorghum hybrid Agri 002E, cultivated in the central region of Mato Grosso do Sul. The design was a randomized block design, with four replications, in a scheme factorial 2x4 and the factors were: two cutting times and four doses of N in topdressing (0, 50, 150 and 200 kg.ha-1). The times of first cutting (FC) were 63 (FC63) and 97 (FC97) days after sowing (DAS). The experiment was repeated after FC until a second cut (SC), at 160 DAS. Plant yeld was evaluated right after each cut. Both cuts were considered as cutting management: 1. FC63, followed by SC 97 (FC63+SC97) and 2. FC97, followed by SC 63 (FC97+SC63). Regardless of the period of permanence of the plants in the field, sorghum yeld was higher in the first cut and the effect of N doses on yield was restricted to the 97-day period preceding SC. The dry matter content ranged from 34.7 to 38.5%. FC97+SC63 was more efficient as it provided the highest yields of fresh (96.6 t.ha-1) and dry (37.9 t.ha-1) matter. |

El objetivo de este trabajo fue evaluar la influencia de las dosis de nitrógeno (N) y el manejo de la corta en el productividad del híbrido de sorgo forrajero Agri 002E, cultivado en la región central de Mato Grosso do Sul. El diseño fue un diseño de bloques al azar, con cuatro repeticiones, en un esquema factorial 2x4 y los factores fueron: dos tiempos de corte y cuatro dosis de nitrógeno en topdressing (0, 50, 150 y 200 kg.ha-1). Los tiempos de primer corte (PC) fueron 63 (PC63) y 97 (PC97) días después de la siembra (DS). El experimento se repitió después de PC hasta un segundo corte (SC), que se produjo 160 días DS. La productividad de la planta se evaluó inmediatamente después de cada corte. Ambos cortes fueron considerados como gestión de corte: 1. PC63, seguido de SC 97 (PC63 + SC97) y 2. PC97, seguido de SC 63 (PC97 + SC63). Independientemente del período de permanencia de las plantas en el campo, el sorgo produjo más en el primer corte y el efecto de las dosis de N sobre el rendimiento se limitó al período de 97 días anterior a la SC. El contenido de materia seca osciló entre el 34,7 y el 38,5%. PC97+SC63 fue más eficiente ya que proporcionó los mayores rendimientos de masa verde (96,6 t.ha-1) y seca (37,9 t.ha-1).O sorgo forrageiro é uma planta com elevado potencial para o Centro Oeste brasileiro, especialmente por ser considerada tolerante a condições adversas e da elevada capacidade de perfilhamento e rebrote das soqueiras após ser cortado para silagem. O objetivo deste trabalho foi avaliar a influência de doses de nitrogênio (N) e o manejo de cortes na produtividade do híbrido de sorgo forrageiro Agri 002E, cultivado na região central de Mato Grosso do Sul. O delineamento foi de blocos ao acaso, com quatro repetições, em esquema fatorial 2x4 e os fatores foram: duas épocas de corte e quatro doses de nitrogênio em cobertura (0, 50, 150 e 200 kg.ha-1). As épocas de primeiro corte (PC) foram aos 63 (PC 63) e 97 (PC 97) dias após a semeadura. O experimento foi repetido após o PC até um segundo corte (SC), que ocorreu após 160 dias da semeadura. Foi avaliada a produtividade das plantas logo após cada corte. Considerou-se como manejo de corte ambos os cortes: 1. PC63, sucedido pelo SC 97 (PC63+SC97) e 2. PC97, sucedido pelo SC 63 (PC97+SC63). Independentemente do período de permanência das plantas ao campo, o sorgo produziu mais no primeiro corte e o efeito das doses de N na produtividade foi restrito ao período de 97 dias que precedeu o SC. O teor de matéria seca variou de 34,7 a 38,5%. O PC97+SC63 foi mais eficiente por proporcionar as maiores produtividades de massa verde (96,6 t.ha-1) e seca (37,9 t.ha-1).Research, Society and Development2021-08-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1940110.33448/rsd-v10i11.19401Research, Society and Development; Vol. 10 No. 11; e109101119401Research, Society and Development; Vol. 10 Núm. 11; e109101119401Research, Society and Development; v. 10 n. 11; e1091011194012525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/19401/17346Copyright (c) 2021 Gustavo de Faria Theodoro; Maryana Martins Ribeiro; Flávia Barbosa de Santana Pacheco; Andrey William Alce Miyakehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessTheodoro, Gustavo de FariaRibeiro, Maryana Martins Pacheco, Flávia Barbosa de SantanaMiyake, Andrey William Alce2021-10-23T19:01:11Zoai:ojs.pkp.sfu.ca:article/19401Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:18.159232Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
