Resumo: The effects of different water depths, applied by trickle irrigation, on the development and crop yield of lettuce (Lactuca sativa L.), cv. Floresta, were evaluated under field conditions. The study was carried out at the Experimental Arca, FEAGRI - UNICAMP, Campinas, SP, Brazil. Four daily water depths were used, based on the percentage of daily evaporation depths measured at a Class A pan (120%, 100%, 80%, 60%). The irrigation arrangement consisted of a completely randomized design with five replications. Due to the high experimental data variability, the results showed no significant difference among treatments for the physiological parameters at different sampling data. However it was possible to conclude that the crop development was affected by the different water depths applied, mainly in its final growth stage. The 120% treatment showed the best results for the total fresh weight, number of leaves per plant and leaf area. The highest average yield (3,582.6 g/m2) and the best marketing quality yield were also obtained in this treatment.

O estudo foi realizado no Campo Experimental, da Faculdade de Engenharia Agrícola, UNICAMP, Campinas, SP, em condições de campo. Foram utilizadas aplicações diárias de água, com quatro níveis de lâmina, baseadas em percentagens (120%, 100%, 80% e 60%) da evaporação do tanque Classe A. O delineamento experimental utilizado foi o inteiramente casualizado, com cinco repetições, perfazendo um total de vinte parcelas. Não foi observada diferença estatisticamente significativa entre os tratamentos, possivelmente em decorrência da alta variabilidade dos dados experimentais. Porém, foi possível concluir que o desenvolvimento da cultura foi afetado pelas diferentes lâminas de água aplicadas, principalmente na fase final do seu ciclo de crescimento. O tratamento com a maior aplicação de água foi o que proporcionou os melhores resultados de massa fresca total, número de folhas por planta e área foliar. A maior produtividade média (3.582,6 g/m2) e as maiores produções de melhor qualidade comercial também foram obtidas nesse tratamento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraHamada, EmiliaTestezlaf, Roberto1995-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4415Pesquisa Agropecuaria Brasileira; v.30, n.9, set. 1995; 1201-1209Pesquisa Agropecuária Brasileira; v.30, n.9, set. 1995; 1201-12091678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4415/1701info:eu-repo/semantics/openAccess2010-06-07T20:26:51Zoai:ojs.seer.sct.embrapa.br:article/4415Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-07T20:26:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
