Resumo: –The objective of this study was to evaluate potato plant growth and macronutrient uptake, as affected by soil tillage methods, in sprinkle and drip irrigated experiments. Eight treatments were set: T1, no tillage, except for furrowing before planting; T2, one subsoiling (SS); T3, twice rotary hoeing (RH); T4, one disc plowing (DP) + twice disc harrow leveling (DL); T5, 1DP + 2DL + 1RH; T6, 1DP + 2DL + 2RH; T7, 1SS + T6; T8, one moldboard plowing (MP) + 2DL. Treatments were arranged in a randomized block design with four replications. In both irrigation systems, plants presented higher emergence velocity index (EVI), when the soil was not tillaged, and the EVI was inversely related to the maximum tuber dry mass production. In both experiments, a functional direct relationship was found between the leaf area index and maximum tuber dry mass yield. The growth of plant organs (tuber, leaf, stem and root) and the macronutrient (N, P, K, Ca and Mg) contents in potato plant responded positively to a deeper soil revolving caused by plowing, especially with moldboard plow.

Em cada experimento, foram estudados oito tratamentos: T1, nenhum preparo do solo, exceto abertura do sulco de plantio; T2, uma subsolagem (SS); T3, duas passadas de enxada rotativa (RH); T4, uma aração com disco (DP)+ duas gradagens niveladoras (DL); T5, 1DP + 2DL + 1RH; T6, 1DP + 2DL + 2RH; T7, 1SS + T6; T8, uma aração com aiveca (MP) + 2DL. Os tratamentos foram distribuídos em blocos ao acaso, com quatro repetições. Em ambos os experimentos, nos tratamentos em que o solo não foi arado, as plantas apresentaram alto índice de velocidade de emergência (EVI). A EVI foi inversamente relacionada com a produção de matéria seca de tubérculos. Também, em ambos os experimentos, foi encontrada uma relação funcional direta entre o índice de área foliar e a máxima produção de matéria seca dos tubérculos. O crescimento dos órgãos (tubérculo, folha, caule e raiz) e o conteúdo de macronutrientes (N, P, K, Ca e Mg) na planta responderam positivamente à maior profundidade de revolvimento do solo, causada pela aração, especialmente com o arado de aiveca.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNunes, Julio Cezar SilveiraFontes, Paulo Cezar RezendeAraújo, Eduardo FontesSediyama, Carlos2006-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7346Pesquisa Agropecuaria Brasileira; v.41, n.12, dez. 2006; 1787-1792Pesquisa Agropecuária Brasileira; v.41, n.12, dez. 2006; 1787-17921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/7346/4391info:eu-repo/semantics/openAccess2014-10-08T18:43:53Zoai:ojs.seer.sct.embrapa.br:article/7346Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-08T18:43:53Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
