Resumo: The objective of this work was to evaluate the effect of nitrogen fertilization on the mineral composition of leaves, initial growth, and yield of peach (Prunus persica) tree advanced selections grown at a high-planting density. The experiment was carried out between 2012 and 2015 in a randomized complete block design, with a combination of advanced selections of the 'Cascata 1513' and 'Cascata 1067' peach trees and of N fertilization doses (0, 30, 60, and 120 kg ha-1 N). Green weight after pruning, diameter, and increase of trunk diameter, canopy volume, plant height, branch length, number of buds per centimeter of shoot, chlorophyll index, leaf area, rust incidence, average production, number of fruit, and mass of fruit were evaluated. Genotype affects the vegetative growth and productive performance of peach trees. The application of N to dense peach orchards promotes a greater vegetative growth of the plants and increases the content of the nutrient in leaves. The initial production is affected by N fertilization. The recommendation of N fertilization made to date is insufficient for peach trees at high-density management systems of production.

O experimento foi conduzido entre 2012 e 2015 em delineamento em blocos ao acaso, com a combinação de seleções avançadas de pessegueiro 'Cascata 1513' e 'Cascata 1067' e de doses de adubação nitrogenada (0, 30, 60 e 120 kg ha-1 de N). A massa de poda, diâmetro e incremento do diâmetro de tronco, volume de copa, altura de plantas, comprimento de ramos, número de gemas por centímetro de ramo, índice de clorofila, área foliar, incidência de ferrugem, produção média e o número e a massa de frutos foram avaliados. O genótipo influencia o crescimento vegetativo e o desempenho produtivo do pessegueiro. A aplicação de N em pomares adensados promove maior crescimento vegetativo das plantas e aumenta o teor do nutriente nas folhas. A produção inicial é influenciada pela adubação nitrogenada. A recomendação de adubação nitrogenada feita até o presente é insuficiente para pessegueiros conduzidos em sistemas de produção adensada.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Empresa Brasileira de Pesquisa Agropecuária (Embrapa)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Ferreira, Letícia VanniPicolotto, LucianoPereira, Ivan dos SantosSchmitz, Juliano DutraAntunes, Luis Eduardo Corrêa2018-03-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25355Pesquisa Agropecuaria Brasileira; v.53, n.2, fev. 2018; 172-181Pesquisa Agropecuária Brasileira; v.53, n.2, fev. 2018; 172-1811678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25355/14137https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25355/17112Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-03-16T20:48:08Zoai:ojs.seer.sct.embrapa.br:article/25355Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-03-16T20:48:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
