Resumo: This paper aimed to evaluate the effect of organic compost fertilization on the post harvest conservation of 'Babá' lettuce. The organic compost was applied at 0.0, 22.8, 45.6, 68.4 and 91.2 ton/ha (dry matter based), with and without a standard mineral fertilizer dosage. The fresh weight loss at room conditions and the chlorophyll degradation were evaluated in cold chamber (4oC) until 84 hours and 12 days after harvest, respectively. Increasing rates of organic compost reduced the post harvest fresh weight loss up to 7%. The chlorophyll content decreased during storage when plants were grown with 45.6 and 91.2 ton/ha of organic compost plus mineral fertilizer, reaching values of 0.3 mg/g of fresh matter. The fertilization with organic compost and mineral fertilizer altogether resulted in plants with early senescence when stored in cold chamber. Increasing doses of organic compost resulted in plants with smaller fresh weight loss in shelf conditions.

O composto orgânico foi aplicado nas doses de 0,0, 22,8, 45,6, 68,4 e 91,2 t/ha de matéria seca. Foram avaliadas a perda de matéria fresca em condições de ambiente e a degradação da clorofila em câmara fria (4oC) até 84 horas e 12 dias, respectivamente, após colheita. A aplicação de doses crescentes de composto orgânico reduziu a perda de matéria fresca após a colheita em até 7%; os teores de clorofila decresceram durante o armazenamento, em plantas adubadas com 45,6 e 91,2 t/ha de composto orgânico e adubo mineral, atingindo cerca de 0,3 mg/g de tecido fresco. A aplicação conjunta de adubo mineral e composto acelerou a senescência de alfaces mantidas em câmara fria, mas o cultivo com composto orgânico reduziu a perda de matéria fresca em condições de ambiente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Ricardo Henrique SilvaSilva, Franceli daCasali, Vicente Wagner DiasCondé, Alcides Reis2001-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6160Pesquisa Agropecuaria Brasileira; v.36, n.3, mar. 2001; 521-525Pesquisa Agropecuária Brasileira; v.36, n.3, mar. 2001; 521-5251678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6160/3225info:eu-repo/semantics/openAccess2010-08-10T16:33:59Zoai:ojs.seer.sct.embrapa.br:article/6160Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-10T16:33:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
