Resumo: | A field experiment was carried out on EPAMIG experimental station at Cambuquira, MG, Brazil, in a Red-Yellow Latosol to study the effects of two liming rates (with and without), three K rates (60-120-180 kg of K2O/ha), applied wholly at the sume time and split three times on the growth and yield of roots of Malaca cultivar sweet potato (Ipomoea batatas Lam.). The lime rate was calculated by exchangeable Al + Ca + Mg method. The treatments improved the chemical soil conditions and nutrient contents of the shoots. The split K fertilization increased the marketable roots production. The largest yield of roots (27,335.2 kg/ha) was obtained in the liming absence. The starch and carotene contents in roots were favorably influenced by K treatments. Generally the liming and the K rates, contributed to improve the chemical soil conditions but, the split K application was the most important to increase the starch, carotene contents and root production. |

A calagem foi feita pelo método do Al, Ca + Mg trocáveis. Os tratamentos melhoraram as condições químicas do solo e os teores de nutrientes da parte aérea. A fertilização potássica parcelada aumentou a produção de raízes comerciáveis. A maior produtividade (27.335,2 kg/ha) foi obtida na ausência da calagem. Os teores de amido e caroteno nas raízes foram influenciados favoravelmente pelos tratamentos com K. Geralmente, as doses de calagem e K contribuíram para melhorar as condições químicas do solo, mas o mais importante para aumentar os conteúdos de amido, caroteno e a produção de raízes foi o filamento do K.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNogueira, Francisco Diasde Carvalho, Vania DeaGuimarães, Paulo Tácito Gontijode Paula, Miralda Bueno1992-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3751Pesquisa Agropecuaria Brasileira; v.27, n.8, ago. 1992; 1129-1139Pesquisa Agropecuária Brasileira; v.27, n.8, ago. 1992; 1129-11391678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3751/1042info:eu-repo/semantics/openAccess2011-08-23T13:32:06Zoai:ojs.seer.sct.embrapa.br:article/3751Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2011-08-23T13:32:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
