No. of bitstreams: 1 2016 - Herton Chimelo Pivoto.pdf: 1107224 bytes, checksum: 991d94d5194f43c503b47b2bd3cdb460 (MD5) Previous issue date: 2015-12-11 / The concern for human health and the environment has led to a growth in the demand and supply of organic or ecological products. The Strawberry (Fragaria x ananassa) in spite of its excellent nutritional characteristics featured in recent years as a product contaminated with pesticides, generating consumer insecurity. And, given the insecurity in relation to their consumption, organic production seeks to regain the confidence of consumers. The aim of this study was to evaluate the feasibility of the production of Strawberry in semi-hidrop?nico organic system cultivated in plastic bags and sugar cane bagasse substrate decomposed. The delineation used was fully randomized blocks with five repetitions. The variables evaluated were: Pseudofrutos number per plant (NF), fresh pasta of Pseudofrutos (MFP), production per plant (PPP), commercial production (CP), Titratable Acidity (AT), hydrogen potential (pH), firm-fleshed (FP), Total soluble solids (TSS), leaf area (AF), leaf area ratio (RAF), leaf (RPF) weight, relative growth rate (TCR), absolute growth rate (TCA) and net assimilat?ria rate (such). Two experiments were carried out in the municipality of S?o Vicente do Sul, Central Rio Grande do Sul, under protected environment, one with a cultivar of photoperiod critical to flowering "short days", the ' Camino Real ' and another with farming, which does not require critical photoperiod for flower "neutral" days, the ' Albion '. Both were grown in semi-hidrop?nico system, involving: four different fertilizer management, which are: fertirrigado with conventional fertilization (control), biofertilizers Agrobio, Super Thin and biofertilizer drawn from commercial organic fertilizer (Ferticel). The growth characteristics of AF, TCR, TCC, RAF, RPF and TAL were influenced significantly by treatments, the results Bioferticel compatible and Biofertilizer in some variables above control for both cultivars. On cultivating actual path there were significant differences for the treatments, and the treatment with Bioferticel had superior results for control variables: NF, PPP, FP, SST, and relationship SSTAT. The levels of nutrients in the leaves of the strawberry Camino Real and Albion were within the recommendation for culture or slightly above in the analysis carried out in full bloom. In the final analysis of cultivation the Super slim and Biofertilizers Agrobio showed levels of phosphorus and potassium below the recommended for culture for both cultivars. The strawberry PC Camino Real was superior in treating Bioferticel, reaching values of gr 650.51.1 and plant 516.36 Gr. 1 plant for the control. To cultivate Albion, there were significant differences for the treatments, and the Control treatment had superior results to other treatments for the variables: NF, PPP, SST, and relationship SSTAT. The strawberry PC Albion was lower than the average considered ideal for the State of Rio Grande do Sul. The biofertilizer Bioferticel in some of the aspects studied, provided superior results to the conventional. So, can be indicated as a means to the substrate semi-hidrop?nico bagasse decomposed for Strawberry cultivation. / A preocupa??o com a sa?de humana e do meio ambiente tem levado a um crescimento na demanda e na oferta de produtos org?nicos ou agroecol?gicos. O morango (Fragaria x ananassa) apesar de suas excelentes caracter?sticas nutricionais figurou nos ?ltimos anos como um produto contaminado por agrot?xicos, gerando inseguran?a ao consumidor. E, diante da inseguran?a em rela??o ao seu consumo, a produ??o org?nica busca recuperar a confian?a dos consumidores. O objetivo deste trabalho foi avaliar a viabilidade da produ??o do morangueiro em sistema semi-hidrop?nico org?nico cultivado em sacos pl?sticos e substrato baga?o de cana decomposto. O delineamento utilizado foi de blocos inteiramente casualizados com cinco repeti??es. As vari?veis avaliadas foram: N?mero de Pseudofrutos por planta (NF), Massa Fresca de Pseudofrutos (MFP), Produ??o por Planta (PPP), Produ??o Comercial (PC), Acidez Titul?vel (AT), Potencial Hidrogeni?nico (pH), firmeza de polpa (FP), S?lidos Sol?veis Totais (SST), ?rea foliar (AF), raz?o de ?rea foliar (RAF), raz?o de peso foliar (RPF), taxa de crescimento relativo (TCR), taxa de crescimento absoluto (TCA) e taxa assimilat?ria l?quida (TAL). Foram realizados dois experimentos no munic?pio de S?o Vicente do Sul, regi?o Central do RS, sob ambiente protegido, um com uma cultivar de fotoper?odo cr?tico para florescimento ?de dias curtos?, a ?Camino Real? e outro com cultivar, que n?o necessita de fotoper?odo cr?tico para florescer ?de dias neutros?, a ?Albion?. Ambas foram cultivadas em sistema semi-hidrop?nico, envolvendo: quatro diferentes manejos de aduba??o, quais sejam: fertirrigado com fertiliza??o convencional (controle), biofertilizantes Agrobio, Super Magro e biofertilizante elaborado a partir de adubo org?nico comercial (Ferticel). As caracter?sticas de crescimento AF, TCR, TCC, RAF, RPF e TAL foram influenciadas significativamente pelos tratamentos, o Biofertilizante Bioferticel obteve resultados compat?veis e em algumas vari?veis superiores ao controle para ambas as cultivares. Na cultivar Caminho Real verificaram-se diferen?as significativas para os tratamentos, sendo que o tratamento com Bioferticel teve resultados superiores ao controle para as vari?veis: NF, PPP, FP, SST, AT e rela??o SST/AT. Os teores de nutrientes nas folhas do morangueiro Camino Real e Albion estiveram dentro da recomenda??o para a cultura ou levemente acima na an?lise realizada em pleno florescimento. Na an?lise de final de cultivo os Biofertilizantes Super Magro e Agrobio apresentaram teores de F?sforo e Pot?ssio abaixo do recomendado para a cultura para ambas as cultivares. A PC do morangueiro Camino Real foi superior no tratamento Bioferticel, atingindo valores de 650,51 gr.planta-1 e de 516,36 gr.planta-1 para o controle. Para a cultivar Albion, verificaram-se diferen?as significativas para os tratamentos, sendo que o tratamento Controle teve resultados superiores aos demais tratamentos para as vari?veis: NF, PPP, SST, AT e rela??o SST/AT. A PC do morangueiro Albion foi inferior ? m?dia considerada ideal para o estado do Rio Grande do Sul. O biofertilizante Bioferticel, em alguns dos aspectos estudados, proporcionou resultados superiores ao Convencional. Assim, pode ser indicado como meio semi-hidrop?nico ao substrato baga?o de cana decomposto para cultivo do Morangueiro
