Resumo: The objective of this work was to evaluate the influence of increasing doses of nitrogen on vegetative growth, yield and leaf nutrient levels of blackberry (Rubus spp.). The experiment was carried out with the cultivars Tupy and Xavante, in southern state of Rio Grande do Sul, Brazil, from 2008 to 2012. It was used a randomized block design, with four replicates. Treatments consisted of five N doses (0.0, 7.5, 15.0, 22.5 and 30.0 g per plant), applied as maintenance fertilization after the crop establishment. The following variables were evaluated: cane density, pruned dry mass, chlorophyll index, yield, number of fruit, and nutritional composition of leaves for N, K, Ca, Mg and S. The fertilization treatments significantly influenced the vegetative growth, yield, and nutrient composition of leaves. The cultivars responded differently to nitrogen application, with 'Tupy' being more demanding than 'Xavante'. The currently recommended nitrogen rate for blackberry cultivation is suitable for maximum yield of 'Xavante', but it is not sufficient for 'Tupy'.

O experimento foi realizado com as cultivares Tupy e Xavante, na região sul do Rio Grande do Sul, de 2008 a 2012. Os tratamentos consistiram da aplicação de cinco doses de N (0,0, 7,5, 15,0, 22,5 e 30,0 g por planta), aplicados na adubação de manutenção, após a implantação da lavoura. Utilizou-se o delineamento de blocos ao acaso, com quatro repetições. Foram avaliadas as variáveis: densidade de hastes, massa de matéria seca de poda, índice de clorofila, produção por planta, número de frutos e composição nutricional das folhas (N, K, Ca, Mg e S). A adubação nitrogenada influenciou significativamente o crescimento vegetativo, a produção e a composição nutricional das folhas. As cultivares apresentaram resposta distinta à aplicação de N, em que 'Tupy' foi mais exigente que 'Xavante'. As doses de N atualmente recomendadas para a cultura da amoreira‑preta são satisfatórias para a máxima produção de 'Xavante', mas insuficientes para 'Tupy'.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq e CAPESPereira, Ivan dos SantosPicolotto, LucianoMessias, Rafael da SilvaPotes, Mariana da LuzAntunes, Luis Eduardo Correa2013-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13683Pesquisa Agropecuaria Brasileira; v.48, n.4, abr. 2013; 373-380Pesquisa Agropecuária Brasileira; v.48, n.4, abr. 2013; 373-3801678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13683/11347https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13683/9241https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13683/9242https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13683/9243https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13683/9244https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13683/9245https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13683/9246https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13683/9247info:eu-repo/semantics/openAccess2013-06-27T17:48:17Zoai:ojs.seer.sct.embrapa.br:article/13683Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-06-27T17:48:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
