Dissertação (Mestrado em Ciências Ambientais) - Universidade Federal de Alfenas, Alfenas, MG, 2018.https://repositorio.unifal-mg.edu.br/handle/123456789/1432Waste from sewage treatment plants are known as biosolids. These are rich in macro and micronutrients (N, P, Ca, Mg, B, Fe, Zn, Cu) among others, which are essential as plants and therefore have potential use in agriculture. The objective of this study was to evaluate the supply of nutrients for the cultivation of White Diamond, as well as the plant nutritional and physiological parameters of growth, to the addition of biosolids in different concentrations without substrate. The nutritional, biochemical, physiological and growth substrates, as the plants were collected and exchanged according to the period of 8 weeks, correspond to the period of realization of the plants. In the reproductive phase, each week, 5 pots were collected from each concentration, totaling 90 plants for analysis. Without laboratory, they were the species of plants of growth and then, were separated according to the species of organ, for determination and quantification of species in the different parts and later verification of the nutritional state. The results were removed and highlighted as S, B, Fe, Mn, Mo in the roots, as well as a high accumulation of Al. In the leaves and inflorescences, larger accumulations of P, Ca, Mg, independent of the biosolid concentration were observed. No stem, no greater accumulations were observed. As a substrate of 60% biosolid, they were promoted as directed to the conditioned plants. As a result of 40% biosolid, promote positive results for an evaluation of the growth, biochemical and physiological variables evaluated. Concentrations above 80% of biosolids were not favorable, as they caused delays in the growth of plants, they promoted plants with low shoot length and root length. It is concluded that the biosolid compound has potential as a source of nutrients not chrysanthemum cultivation. Concentrations of up to 40% of biosolid, the best physical sources to the substrate and nutritional as plants, when making new plants with better rates of growth and development, according to demanding standards in the market. Therefore, the use of the Bosporus in the cultivation of potted chrysanthemums is an excellent alternative to destine this product.application/pdfAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/ChrysanthemumNutriçãoFisiologiaPropriedades Físico-químicas.CIENCIAS BIOLOGICASDissertaçãoBarbosa, Sandro
