Resumo: | The trial was carried out at Santana da Vargem, State of Minas Gerais, Brazil, from September to November 2003, with the objective of evaluating the productivity and nutritional state of lettuce cultivars in function of the Si addition. The experimental design was in randomized blocks with four replicates, in factorial arrengement with additional treatments: 3 x 4 +3, composed by three lettuce cultivars: Raider (group crisphead); Regina (group loosen smooth) and Vera (group loosen crisped) and four Silifértil® rates (0, 1, 2 and 4 t ha-1). The additional treatments were composed by the application of 3.5 t.ha-1 of Limestone for the three cultivars.The nutritional status of lettuce was evaluated by Diagnosis and Integrated Recommendation System. The application of Si in the form of Silifértil® do not increase the yield of the lettuce Rider, Regina and Vera. The fertilization with Silifértil® do not increase the silicon concentration in the aerial part of the lettuce, increase the DRIS indice for Si, but do not change the concentrations of most of the nutrients analyzed, except for the concentration of the K and Zn. The concentration of K decreased in function inverse polinomial, with low point in 1,89 t ha-1 of Silifértil®, and without adjusting, a regression curve, the tenor of Zn, decreased with the increase of the rate of Silifértil®. The fertlization with Silifértil® do not promote one better nutritional status for lettuce crops. |

O experimento foi conduzido no município de Santana da Vargem, sul de Minas Gerais, no período de setembro a novembro de 2002, no delineamento experimental em blocos casualizados, com quatro repetições, em esquema fatorial 3 x 4 com 3 tratamentos adicionais: cultivares de alface: Raider (grupo crespa repolhuda); Regina (grupo solta lisa) e Vera (grupo solta crespa) e quatro doses de Silifértil® (0, 1, 2 e 4 t ha-1). Os tratamentos adicionais foram compostos pela aplicação de 3,5 t.ha-1 de calcário dolomítico para as três cultivares. O estado nutricional das plantas de alface foi avaliado pelo Sistema Integrado de Diagnose e Recomendação. A aplicação de Si na forma de Silifértil® não aumentou a produtividade das cultivares de alface Rider, Regina e Vera. Também não aumentou o teor de Si na parte aérea da alface, mas aumento o valor do indice DRIS para Si, não afetando os teores da maioria dos outros nutrientes analisados, com exceção dos teores de K e Zn. O teor de K diminuiu em função polinomial inversa, com ponto de mínima em 1,89 t ha-1 de Silifértil® e, sem ajustar, estatisticamente, uma curva de regressão, o teor de Zn, diminuiu com o aumento da dosagem de Silifértil®. A adubação com Silifértil®, não promoveu um melhor estado nutricional para a alface cultivada.Universidade Federal Rural do Semi-Árido (UFERSA)2020-10-15T22:54:24Z2020-10-15T22:54:24Z2009-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFERREIRA, R.
