Resumo: Effects of three irrigation treatments on bean (Phaseolus vulgaris L.) growth were studied. Treatments consisted of irrigating when soil-water tension reached 125mb, 250mb and 750mb. There was a marked reduction in growth with increasing soil-water tension, even at relatively low values. Loaf area index (L), leaf area duration (D), dry matter production (Wt), crop growth rate (Ct), relative growth rate (Rw) and net assimilation rate (EA) decreased as the irrigation was carried out at higher soil-water tension. The dry matter production decrease was attributed to the decrease in L and EA. As the soil-water tension increased the L maximum value decreased and occurred sooner, due to early loaf senescence. This, in turn, influenced grain yield, which was highly correlated to D.

Houve marcante redução no crescimento com o aumento da tensão da água do solo, mesmo a valores de tensão relativamente baixos. O índice de área foliar (L), a duração da área foliar (D), o rendimento (Wt) e a taxa de produção de matéria seca (Ct), a taxa de crescimento relativo (Rw) e a taxa assimilatória líquida (EA) decresceram à medida que a irrigação foi feita com tensões mais elevadas. A redução na Ct foi devida à redução em L e FA. Com o decréscimo na disponibilidade da água do solo, o L máximo foi menor e ocorreu mais cedo em face da senescência precoce das folhas. Isto influiu diretamente na produção de grãos, pois ela foi altamente correlacionada com D.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraStone, Luis Fernandode Aquino Portes, TomásAlves Moreira, José Aloísio2014-09-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/20397Pesquisa Agropecuaria Brasileira; v.23, n.5, maio 1988; 501-510Pesquisa Agropecuária Brasileira; v.23, n.5, maio 1988; 501-5101678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/20397/12759info:eu-repo/semantics/openAccess2014-09-11T19:05:43Zoai:ojs.seer.sct.embrapa.br:article/20397Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-11T19:05:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
