Considerando tais aspectos, este trabalho teve como objetivo avaliar o desenvolvimento fitot?cnico de plantas frut?feras e oler?colas, utilizando substratos desenvolvidos de res?duos de fibrilose oriundo de uma f?brica de papel e lodo de esgoto da Esta??o de tratamento de esgoto de Te?filo Otoni - MG. O res?duo de fibrilose foi coletado no p?tio de deposi??o de res?duo da f?brica de papel Santher, localizada em Governador Valadares - MG. O material coletado foi conduzido ao laborat?rio de ?gua e solos da Universidade Federal dos Vales do Jequitinhonha e Mucuri, localizado em Te?filo Otoni - MG. O material foi peneirado em peneira de malha de 5 mm para uniformiza??o de suas part?culas e mantido sob secagem ambiente durante uma semana. O lodo de esgoto tratado foi obtido da ETE de Te?filo Otoni, coletado no leito de secagem e conduzido ao laborat?rio sendo autoclavado e peneirado em peneiras de malha 5 mm para padroniza??o de suas part?culas. Em seguida, foi promovida a mistura do res?duo de fibrilose com o lodo de esgoto nas propor??es: T1 (4,5:5,5), T2 (5,5:4,5), T3 (6,5:3,5), T4 (7,5:2,5) e T5 (8,5:1,5) (fibrilose: lodo de esgoto) (Vol: Vol) em litros. Os materiais foram homogeneizados e mantidos em caixas de isopor durante 35 dias, visando ? estabiliza??o do composto. Os outros tratamentos utilizados foram: solo org?nico, composto org?nico Fertiliza ? e substrato Bioplant ?. Ap?s essa etapa foram utilizadas placas de isopor com c?lulas para produ??o de mudas. Ap?s o preenchimento das c?lulas foram semeadas sementes de Mam?o (Carica papaya), Maracuj? (Passiflora sp.), Berinjela (Solanum melongena), Piment?o (Capscium annuum) e Tomate (Licopersicum sp.). Foram utilizadas 36 c?lulas por parcela experimental e o experimento com cinco repeti??es. O delineamento experimental utilizado foi o inteiramente casualisado. Ap?s a germina??o foi avaliado o ?ndice de sobreviv?ncia das pl?ntulas. Em seguida, realizado um desbaste mantendo-se uma pl?ntula por c?lula durante 30 dias. Ap?s este per?odo as plantas foram coletadas e avaliados as seguintes vari?veis: comprimento por parte a?rea, comprimento da raiz, peso seco da raiz e parte a?rea. A an?lise estat?stica foi realizada utilizando o programa Estatjab da Unesp. As an?lises qu?micas dos substratos foram realizadas de acordo com o boletim de recomenda??o 3051 USEPA. Os resultados apontaram maior ?ndice de sobreviv?ncia do maracuj?, comparada com as demais esp?cies testadas e as an?lises qu?micas apontaram que os substratos produzidos de lodo de esgoto e fibrilose estavam de acordo aos padr?es da CONAMA 375/2006 e em concord?ncia com o MAPA, que disp?e sobre normas para o uso de substratos na agricultura. A eleva??o dos n?veis de mangan?s e pot?ssio provavelmente potencializaram a morte das pl?ntulas de berinjela e maracuj?, respectivamente. Em rela??o ao desenvolvimento das pl?ntulas, verificou-se que o composto fibrilose/ lodo de esgoto, nas propor??es T3 e T4 (fibrilose/ lodo de esgoto) apresentou resultados positivos e em muitos casos superiores quando comparado ao substrato comercial e demais materiais org?nicos. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Tecnologia, Sa?de e Sociedade, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / Brazilian agribusiness and family agriculture have a great potential for development considering the country's soil and climate conditions. One of the main factors favoring plant development is the characteristic of the substrates used for the production of seedlings, considering that the productive development of the plants is closely linked to its initial development phase. Considering these aspects, the objective of this work was to evalue the phytotechnical development of fruit and vegetable plants, using substrates developed from fibrilose residues from the paper and sewage sludge plant of the Te?filo Otoni MG sewage treatment plant. The fibrilose residue was collected in the waste disposal yard of the Santher paper mill, located in Governador Valadares - MG. The collected material was taken to the water and soil laboratory of the Federal University of the Jequitinhonha and Mucuri Valleys, located in Te?filo Otoni, MG. The material was sieved in a 0.5 cm mesh sieve for uniformization of its particles and kept under ambient drying for one week. The treated sewage sludge was obtained from the Te?filo Otoni ETE, collected in the drying bed and taken to the laboratory, being autoclaved and sieved in 0.5 cm mesh sieves to standardize its particles. Then the mixture of the fibrilose residue with the sewage sludge was promoted in the proportions: T1(4,5:5,5), T2 (5,5:4,5), T3(6,5:3,5), T4(7,5:2,5) e T5(8,5:1,5) (Fibrilose: sewage sludge) (vol: vol). the materials were mixed and kept in styrofoam boxesfor 28 days, aiming at the stabilization of the blend. The other treatments used were: organic soil, Fertilize organic? compound and Bioplant? substrate. After this step styrofoam plates were used with cells to produce the seedlings. After filling the cells for seedling production, seeds of Papaya (Carica papaya) were sown; Passion fruit (Passiflora sp.), Eggplant (Solanum melongena), bell pepper (Capsicum annuum) and Tomato (Licopersicum sp.) 36 cells were used per experimental plot and the experiment with five replicates. The experimental design was entirely randomized. After germination, one seedling per cell was maintained. The following variables were evaluated: seedling survival index, shoot length, root length, root dry weight and aerial part. Statistical analysis was performed using the Statistical Program of Unesp. The chemical analyzes of the substrates were performed according to UESPA 3051. The results indicated a higher index of survival of the passion fruit compared to the other species tested and chemical analyzes indicated that the substrates produced from sewage sludge and fibrillose are in agreement with the standards of CONAMA 375/2006 and ing agreement with the MAPA, which has Standards for the use of substrates in agriculture. The elevation of manganese and potassium levels potentiated the death of eggplant and passion fruit seedlings, respectively. In relation to the development of the seedlings, it was verified that the fibrilose/ sewage sludge mixture, in the proportions T3 and T4 (Fibrillose / sewage sludge) presented positive results and in many cases higher When compared to the commercial substrate and other organic materials.
