Previous issue date: 2012 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (Capes) / O crescimento populacional e o cen?rio industrial t?m aumentado ? produ??o de res?duos s?lidos e l?quidos. Este trabalho teve como objetivo avaliar o uso do composto de res?duos da ind?stria t?xtil na cultura da alface, em campo. As doses de composto org?nico de res?duos da ind?stria t?xtil foram 0; 7,5; 15; 30 e 60 m3 ha-1 e essas foram comparadas as mesmas doses de vermicomposto e a dose de 40 m3 ha-1 de esterco bovino (tratamento adicional). Os tratamentos foram dispostos em delineamento em blocos ao acaso, com quatro repeti??es em esquema de parcela subdividida, sendo as parcelas as fontes de fertilizantes e as subparcelas as doses. A dose econ?mica m?xima de composto para a massa fresca da parte a?rea foi de 27,9 m3 ha-1. Em rela??o ao vermicomposto, o composto promoveu maiores teores de P, Cu e Mn e resultado semelhante quanto ? respira??o basal, n?mero de folhas, perda acumulada de massa fresca, senesc?ncia e teores de N, K, Ca, S, B, Zn e Fe. Em rela??o ao esterco, estimou-se que dose equivalente do composto promove maiores teores de carbono org?nico e de macronutrientes, e foi semelhante quanto ? respira??o basal, perda acumulada de massa fresca, senesc?ncia e teores B, Zn, Fe e Mn. Em rela??o a outros res?duos citados na literatura o composto promoveu maior ou igual di?metro m?ximo da cabe?a, n?mero de folhas, massa fresca da parte a?rea, perda acumulada de massa fresca, teores de N, P, K, S, B, Zn e Cu. Os teores de Cu e Mn nas plantas de alface fertilizadas com o composto foram abaixo dos valores considerados t?xicos para consumo humano. A compostagem foi eficiente para o tratamento dos res?duos t?xicos da ind?stria t?xtil e o composto pode ser usado em substitui??o ao esterco bovino na cultura da alface. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2012. / ABSTRACT Population growth and industrial landscape have increased the production of solid and liquid waste. This study aimed to evaluate the use of compost waste from the textile industry in lettuce in the field. The doses of organic waste from the textile industry were 0; 7,5; 15, 30 and 60 m3 ha-1 and these were compared with the same doses of vermicompost and the dose of 40 m3 ha-1 of cattle manure (additional treatment). The treatments were arranged in randomized blocks, with four replications in a split-plot, and the sources of fertilizer plots and subplots doses. The economic dose of compound for maximum fresh weight of shoots was 27,9 m3 ha-1. In relation to humus, compost showed higher levels of P, Cu and Mn and a similar result as the basal respiration, leaf number, cumulative loss of weight, senescence and N, K, Ca, S, B, Zn and regarding Fe manure, it was estimated that the equivalent dose of the compound promotes higher levels of organic carbon and nutrients, and was similar for basal respiration, accumulated loss of weight, senescence and B levels, Zn, Fe and Mn. For other wastes reported in the literature the compound promoted or greater diameter of the head, leaf number, shoot fresh weight, cumulative loss of weight, N, P, K, S, B, Zn and Cu . The Cu and Mn in lettuce fertilized with compost were below those toxic for human consumption. Composting is effective for treatment of toxic waste from the textile industry and the compound can be used in place of manure on lettuce.
