Resumo: An experiment was carried out under greenhouse conditions to assess the effect of seven different Azolla species on the growth of flooded rice using Azolla as an alternative source of nitrogen, incorporated into the soil of grown in dual culture. The treatments used were: no added nitrogen (control), 30 and 60 kg/ha of N, Azolla incorporated into the soil and grown in dual culture. Rice development was better using 30 and 60 kg/ha of N and when Azolla was incorporated into the soil. The A. caroliniana, A. filiciloides, A. mexicana and A. microphyllashowed good response. The results suggest the necessity of selecting Azolla species with a high potential as nitrogen source to flooded rice, as well as confirm their value as green manure for this culture.

Os tratamentos utilizados foram: sem adição de fonte de N (testemunha), 30kg/ha de N, 60kg/ha de N, incorporação e cultivo simultâneo da Azolla. O melhor desenvolvimento do arroz foi alcançado com a aplicação de 30 e 60kg/ha de N e incorporação de Azolla no solo. As maiores contribuições foram dadas pela A. caroliniana, A.filiculoides, A. mexicana e A. microphylla. Os resultados indicam a necessidade de selecionar espécies de Azolla que ofereçam maior potencial de utilização do N-Azolla pelo arroz, bem como confirmam os benefícios desse adubo verde no desenvolvimento dessa cultura.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFiore, Marli de FátimaBonetti, RobertoTsai, Siu Mui2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15862Pesquisa Agropecuaria Brasileira; v.24, n.6, jun. 1989; 655-661Pesquisa Agropecuária Brasileira; v.24, n.6, jun. 1989; 655-6611678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15862/9942info:eu-repo/semantics/openAccess2014-08-26T19:55:41Zoai:ojs.seer.sct.embrapa.br:article/15862Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-26T19:55:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
