Resumo: | The presence of brackish water in the Brazilian semi-arid, which is used for the diffuse communities, requires that the reduced cost allows the use of the resource for the cultivation of vegetables commonly used in the region. Thus, the objective of this work was to evaluate the management of nutrient solutions prepared in brackish waters, aiming to validate the cultivation of rocket (Folha larga cv.) in low cost hydroponics, whose main focus is the use in diffuse communities by the Brazilian semi - arid. To do this, two experiments were carried out in which the use of six salinity levels of the nutrient solution (1.5, 3.0, 4.5, 6.0, 7.5 and 9 dS m-1) and two circulation frequencies (2 and 3 times a day, namely at 8 and 16 hours and at 8, 12 and 16 hours), but in Experiment I, the evapotranspiration was replaced with the brackish water used in the preparation of the nutrient solution and in Experiment II the water was filled with water (0.1 dS m 1). These treatments were distributed in a completely randomized experimental design, analyzed in a 6 x 2 factorial scheme, with five replications. In this way, there were lower losses in the hydric relations and in the biomass production of the aerial part of the rocket, when it was replaced with water supply, in addition, the consumption and the efficiency of water use were reduced by the saline increment, independently of the strategy of replacement of the evapotranspirated sheet. Both for replenishment with water supply and brackish water, the increase gives electrical conductivity of the nutritive solution provided a decrease in the production of flesh and dry biomass, in the percentage of dry mass an in the biometry of the plants. The increase in the frequency of circulation did not influence the biometric variables, however, under a higher frequency of circulation the plant prioritized the development of the biomass of the aerial part in detriment of the root. |

Dissertação (Programa de Pós-Graduação em Engenharia Agrícola) - Universidade Federal Rural de Pernambuco, Recife.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/7625The presence of brackish water in the Brazilian semi-arid, which is used for the diffuse communities, requires that the reduced cost allows the use of the resource for the cultivation of vegetables commonly used in the region.

Dessa forma, o objetivo do trabalho foi avaliar estratégias de manejo de soluções nutritivas preparadas em águas salobras, no cultivo da rúcula (cv. Folha larga) em hidroponia de baixo custo, cujo foco principal é o uso em comunidades difusas pelos Semiárido Brasileiro. Para tal, foram realizados dois experimentos nos quais foram testados a utilização de seis níveis de salinidade da solução nutritiva (1,5; 3,0; 4,5, 6,0; 7,5 e 9 dS m-1) e duas frequências de circulação da solução (2 e 3 vezes ao dia, a saber, às 8 e às 16 horas e às 8, 12 e 16 horas), porém, no Experimento I a reposição da lâmina evapotranspirada foi feita com a respectiva água salobra dos usada no preparo da solução nutritiva e no Experimento II as águas foram repostas com água de abastecimento (0,12 dS m-1). Estes tratamentos foram distribuídos em um delineamento experimental inteiramente casualizado, analisado em esquema fatorial 6 x 2, com cinco repetições. Através disso, verificaram-se menores perdas nas relações hídricas e na produção de biomassa da parte aérea na rúcula, quando adotou-se reposição com água de abastecimento, além disso, o consumo e a eficiência do uso da água foram reduzidos pelo incremento salino, independentemente da estratégia de reposição da lâmina evapotranspirada. Tanto para reposição com água de abastecimento e com água salobra, o aumento da condutividade elétrica da solução nutritiva proporcionou diminuição na produção de biomassa fresca e seca, no percentual de massa seca e na biometria das plantas. O aumento da frequência de circulação não influenciou as variáveis biométricas, no entanto, sob maior frequência de circulação a planta priorizou o desenvolvimento da biomassa da parte aérea em detrimento da raiz.Submitted by Mario BC (mario@bc.ufrpe.br) on 2018-10-02T17:00:38Z No. of bitstreams: 1 Jose Eustaquio Campos Junior.pdf: 1957947 bytes, checksum: 2781cd450c1df938a8797719317b55e8 (MD5)Made available in DSpace on 2018-10-02T17:00:38Z (GMT).

The presence of brackish water in the Brazilian semi-arid, which is used for the diffuse communities, requires that the reduced cost allows the use of the resource for the cultivation of vegetables commonly used in the region. Thus, the objective of this work was to evaluate the management of nutrient solutions prepared in brackish waters, aiming to validate the cultivation of rocket (Folha larga cv.) in low cost hydroponics, whose main focus is the use in diffuse communities by the Brazilian semi - arid. To do this, two experiments were carried out in which the use of six salinity levels of the nutrient solution (1.5, 3.0, 4.5, 6.0, 7.5 and 9 dS m-1) and two circulation frequencies (2 and 3 times a day, namely at 8 and 16 hours and at 8, 12 and 16 hours), but in Experiment I, the evapotranspiration was replaced with the brackish water used in the preparation of the nutrient solution and in Experiment II the water was filled with water (0.1 dS m 1). These treatments were distributed in a completely randomized experimental design, analyzed in a 6 x 2 factorial scheme, with five replications. In this way, there were lower losses in the hydric relations and in the biomass production of the aerial part of the rocket, when it was replaced with water supply, in addition, the consumption and the efficiency of water use were reduced by the saline increment, independently of the strategy of replacement of the evapotranspirated sheet. Both for replenishment with water supply and brackish water, the increase gives electrical conductivity of the nutritive solution provided a decrease in the production of flesh and dry biomass, in the percentage of dry mass an in the biometry of the plants. The increase in the frequency of circulation did not influence the biometric variables, however, under a higher frequency of circulation the plant prioritized the development of the biomass of the aerial part in detriment of the root. |
