Resumo: | We aimed to study the effect of N fertilization on leaf composition, yield and quality of rubber of trees of Hevea brasiliensis Muell. Arg. and how the responses relate to plant N status at the previous growing season. The experiment was carried out in a commercial rubber plantation, located in the municipality of Barbosa, São Paulo State, with 12-year-old trees and first tapping. The treatments corresponded to fertilization with N at the recommended rate (50 kg ha-1) and excessive rates (100 and 200 kg ha-1); a control without application of the nutrient was also included. Tree nutritional status, yield and quality of rubber were evaluated. The results revealed a decreasing linear effect of N on yield. The highest N rate also affected latex quality, as revealed by a decreasing in the values of parameters associated with mechanical strength. There was an increase in leaf concentration of N, P and K, while Ca was reduced. Our results, therefore, suggest that leaf analysis could be a complementary tool for adjusting N fertilization of rubber trees and contribute to reduce the |

Arg. na estação de crescimento anterior. O trabalho foi conduzido em área comercial, situada no município de Barbosa, SP, utilizando árvores com 12 anos de plantio e no primeiro ano de sangria. Os tratamentos corresponderam, além do controle, à fertilização com N na dose recomendada (50 kg ha-1) e em excesso (100 e 200 kg ha-1), com avaliação do estado nutricional das árvores, a produção e a qualidade de borracha. Os resultados revelaram efeito linear decrescente das doses de N sobre a produtividade das árvores. Adicionalmente, a aplicação 200 kg ha-1 de N afetou a qualidade do produto, devido à diminuição da resistência mecânica da borracha. Em função das doses de N, houve aumento na concentração foliar de N, P e K, mas redução de Ca. Conclui-se que a análise foliar poderia ser uma ferramenta auxiliar para definir doses adequadas de adubação nitrogenada para a cultura da seringueira no início da fase produtiva, evitando-se efeitos negativos do desequilíbrio nutricional sobre a performance produtiva e a qualidade da borracha.Embrapa Florestas2022-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/213410.4336/2022.pfb.42e202002134Pesquisa Florestal Brasileira; v. 42 (2022)Pesquisa Florestal Brasileira; Vol. 42 (2022)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2134/1673Copyright (c) 2022 William Gutieli Gouveia Luiz, Geisa Lima Mesquita, Felipe Oliveira Souza, Marcos Leandro Martins, Juliana Iassia Gimenez, Fernando César Bachiega Zambrosihttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessLuiz, William Gutieli GouveiaMesquita, Geisa LimaSouza, Felipe OliveiraMartins, Marcos LeandroGimenez, Juliana IassiaZambrosi, Fernando César Bachiega2022-12-14T14:46:53Zoai:pfb.cnpf.embrapa.br/pfb:article/2134Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2022-12-14T14:46:53Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
