Resumo: The objective of this work was to study spatial variability of some chemical soil attributes and lettuce production (total shoot fresh matter mass - MF; commercial shoot fresh matter mass - MFC; commercial shoot dry matter mass - MCS; and head commercial diameter - DCC) offering subsidies to the protected environment mapping in nutrients management areas in lettuce culture aiming for a higher productivity with application of fertilizers. The experiment was conducted in a protective environment (greenhouse) with lettuce irrigated by drip irrigation and sampling grid with 152 points. The special dependence analysis, determined by the variogram, was obtained with the aid of the GS+ Program. Considering the need for crop nutrients through the map obtained for element P (phosphorus) it was possible to establish two distinct areas for the application of this element in plantation fertilization. Through the lettuce yield maps obtained with MFC and DCC attributes was difficult to establish distinct areas for its management with data observed in only one crop cycle. Krigagem has proved useful for mapping the attributes studied.

O experimento foi conduzido em ambiente protegido com alface irrigada por gotejamento e malha de amostragem com 152 pontos. A análise da dependência espacial, determinada pelo variograma, foi obtida com o auxílio do Programa Geoestatístico GS+. Considerando-se a necessidade da cultura em nutrientes, através do mapa obtido para o P, foi possível estabelecer duas áreas distintas de manejo para o elemento na adubação mineral de plantio da cultura de alface. Através dos mapas de produção de alface, obtidos com os atributos MFC e DCC, foi difícil estabelecer.Grupo de Estudos e Pesquisas Agrárias Georreferenciadas(GEPAG) Faculdade de Ciências Agronômicas Universidade Estadual Paulista, Botucatu, SPDepartamento de Recursos Naturais Faculdade de Ciências Agronômicas Universidade Estadual Paulista, Botucatu, SPGrupo de Estudos e Pesquisas Agrárias Georreferenciadas(GEPAG) Faculdade de Ciências Agronômicas Universidade Estadual Paulista, Botucatu, SPDepartamento de Recursos Naturais Faculdade de Ciências Agronômicas Universidade Estadual Paulista, Botucatu, SPUniversidade Estadual Paulista (Unesp)Batista, Ivana Furio [UNESP]Zimback, Célia Regina Lopes [UNESP]2014-05-27T11:25:23Z2014-05-27T11:25:23Z2010-12-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article401-413application/pdfhttp://irriga.fca.unesp.br/index.php/irriga/article/view/133Irriga, v. 15, n. 4, p. 401-413, 2010.1413-78951808-3765http://hdl.handle.net/11449/721332-s2.0-799579503462-s2.0-79957950346.pdfScopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengporIrriga0,283info:eu-repo/semantics/openAccess2024-04-30T19:28:30Zoai:repositorio.unesp.br:11449/72133Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-04-30T19:28:30Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
