Resumo: | The preparation of nodulated fine roots of cowpea is an alternative of inoculation with strains that perform the biological fixation of microbial community nitrogen locally adapted to the climatic and soil conditions, as well as to the local varieties. This work intends to evaluate the effect of inoculation from a fine root preparation on the vegetative growth of cowpea in comparison to commercial inoculation, urea fertilization and combinations thereof. The design was completely randomized with four replicates and the following treatments: T1: Witness; T2: Inoculum with roots; T3: Commercial inoculum; T4: Inoculum with roots + fertilization with urea in coverage; T5: Commercial inoculum + fertilization with urea under cover and T6: Fertilization with urea under cover. Root inoculation treatment plus cover nitrogen fertilization provided higher root length (57.25 cm) compared to treatment with only nitrogen fertilization in the cover (42.00 cm). In relation to the number of nodules at the 48 DAE, it was verified that the inoculation with roots was superior to the control and the nitrogenous fertilization in coverage. It was also observed that the SPAD index was lower in the control (40.25 g kg -1) and in urea fertilization (40.55 g kg -1). Fertilization with 20 kg ha-1 of urea resulted in lower root and shoot growth, number of nodules, dry mass of the plant part and SPAD index. The use of root inoculation is a viable alternative for the family farmer and agroecological based producers, but it needs to be evaluated in the field. |

Esse trabalho avaliou o efeito da inoculação a partir de um preparado de raízes finas sobre o crescimento vegetativo do feijão-caupi, em comparação a inoculação comercial, adubação com ureia e suas combinações. O delineamento usado foi inteiramente ao acaso com quatro repetições e os seguintes tratamentos: T1- Testemunha (sem inoculação e adubação nitrogenada); T2- Inóculo com raízes; T3- Inóculo comercial; T4- Inóculo com raízes + adubação nitrogenada em cobertura; T5- Inóculo comercial + adubação nitrogenada em cobertura e T6- Adubação nitrogenada em cobertura. O tratamento inóculo com raízes + adubação nitrogenada em cobertura (T4) proporcionou maior comprimento radicular (57,25 cm) comparado ao tratamento com adubação nitrogenada em cobertura (T6) com42,00 cm. Para o número de nódulos aos 48 DAE, verificou-se que a inoculação com raízes (T2) foi superior a testemunha (T1) e a adubação nitrogenada em cobertura (T6). Os menores valores para o índice SPAD ocorreram na testemunha (40,25 g kg-1) e na adubação com ureia em cobertura (40,55 g kg-1). O tratamento com adubação nitrogenada em cobertura (20 kg ha-1 de ureia) implicou em menor crescimento da raiz e da parte aérea, número de nódulos, massa seca da parte da planta e índice SPAD. O uso da inoculação com raízes é uma alternativa viável para o agricultor familiar e produtores de base agroecológica, porém precisa ser avaliada em campo.Editora Verde2018-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfapplication/pdfapplication/pdfapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/563010.18378/rvads.v13i4.5630Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 No. 4 (2018); 466 - 471Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 Núm. 4 (2018); 466 - 471Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 13 n. 4 (2018); 466 - 4711981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/5630/5925https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5630/5926https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5630/9515https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5630/9516https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5630/9518Copyright (c) 2018 Victor Roberto Ribeiro Reis et al.info:eu-repo/semantics/openAccessReis, Victor Roberto RibeiroSouza, Letícia Raquel SilvaVieira, George Luiz SouzaCoelho, Karla Brieny SousaCarmo Filho, Abimael dos SantosSilva, Maria Rosangela Malheiros2021-06-14T13:13:53Zoai:ojs.gvaa.com.br:article/5630Revistahttps://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:2024-03-06T12:59:26.112471Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
