Resumo: A field experiment was conducted at National Rice and Bean Research Center, EMBRAPA, Goiânia, to study the effects of different technologies used by farmers as compared with that recommended by research on growth, yield and pattern of nutrients uptake of upland rice (Oryza sativa L.). Relative growth rate and relative plant height reduced with advancing age of the plant in both technology levels tested. Accumulation of P, K, Ca, Mg and Zn increased with increasing plant age. Application of fertilizer based on soil analysis increased yield significantly. Similar effect was obtained with respect to weed control with two hand weedings.

As taxas relativas de crescimento e de altura diminuíram com a idade das plantas, em ambos os níveis de tecnologia testados. A acumulação de K, Ca, Mg, P e Zn aumentaram com a idade das plantas. A adubação baseada na análise do solo e o controle de ervas daninhas com duas capinas aumentaram significativamente a produção de grãos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Alberto Baêta dosFageria, Nand KumarCarvalho, José Ruy Porto de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15986Pesquisa Agropecuaria Brasileira; v.17, n.7, jul. 1982; 1041-1050Pesquisa Agropecuária Brasileira; v.17, n.7, jul. 1982; 1041-10501678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15986/10111info:eu-repo/semantics/openAccess2014-04-16T16:21:37Zoai:ojs.seer.sct.embrapa.br:article/15986Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:21:37Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
