Resumo: | Direct seeding and the planting of winter crops for soil cover are techniques which have acquired importance in maintaining or increasing productivity of summer crops. The objective of this study was to determine the effect of soil management systems (conventional and direct planting), and fertilization levels (zero, half and recommended doses of N, P2O5, K2O and B) in sunflower (Helianthus annuus L.) culture in two cultivation systems preceeding the culture (with Avena strigosa or in fallow). The experiment was carried out in the 1990/91 and 1991/92 growing seasons, in the EEA/UFRGS, in the Central Depression of Rio Grande do Sul. Grain yield of sunflower and the leaf nitrogen content were affected by the fertilization level, being smaller in the treatments without fertilization. Data relative to stem diameter, plant stature and root length showed that the sunflower plants presented greater growth in the conventional soil management system, and in succession to Avena strigosa. |

O presente trabalho, conduzido durante duas estações de crescimento, teve como objetivo determinar o efeito de sistemas de manejo do solo (convencional e plantio direto), e níveis de adubação (zero, metade e dose recomendada de N, P2O5, K2O e B) na cultura do girassol (Helianthus annuus L.), em dois sistemas de cultivo antecedendo a cultura (com aveia-preta ou em condições de pousio). O experimento foi realizado nos anos agrícolas de 1990/91 e 1991/92, na EEA/UFRGS, na Depressão Central do Rio Grande do Sul. O rendimento de grãos de girassol e o teor de N na folha foram afetados pelo nível de adubação, sendo inferiores nos tratamentos sem adubação. Os dados relativos a diâmetro de caule, estatura da planta e comprimento das raízes evidenciaram que as plantas de girassol apresentam maior crescimento no sistema convencional de manejo do solo, e em sucessão à aveia-preta.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFerreira da Silva, Paulo RegisWendt, WilsonBrondani da Rocha, Andréa1997-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4694Pesquisa Agropecuaria Brasileira; v.32, n.6, jun. 1997; 641-647Pesquisa Agropecuária Brasileira; v.32, n.6, jun. 1997; 641-6471678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4694/7352info:eu-repo/semantics/openAccess2015-04-06T19:35:03Zoai:ojs.seer.sct.embrapa.br:article/4694Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-04-06T19:35:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
