“…In a study conducted by Cazuza Neto et al (2014) with NFT hydroponics, at 26 DAT, the production of fresh matter of the bunch of 8 plants of 'Verdão' coriander was equal to 92.66 g, for the control treatment (EC = 0.30 dS m -1 ). The results observed in the present study at 25 DAT were lower, and this difference is associated with characteristics of cultivation system, cycle and cultivation period, besides the strong effect of plant density along the cultivation unit, which may have led to competition between plants for light and nutrients, since plants were cultivated in plastic cups spaced at 30 cm, compared with the 7-cm spacing in the present study.…”

A B S T R A C TThe present study used a hydroponic system with leveled channels, in order to evaluate coriander cultivation under different intervals of nutrient solution recirculation and the use of freshwater and brackish water. The experiment was carried out in a randomized block design with five replicates, in a 2 x 4 factorial scheme, from February to March 2014. Two levels of electrical conductivity (EC) of water (0.32 and 4.91 dS m -1 ) and four frequencies of nutrient solution recirculation (at intervals of 0.25, 2, 4 and 8 h) were evaluated. This experimental design was adopted in the evaluations performed at 10, 15 and 25 days after transplantation (DAT). Additionally, at 21 DAT subplots were established for the evaluation of plant position (initial, intermediate and final) along the hydroponic channels. It is viable to use nutrient solution recirculation every 8 h, without production losses. The use of brackish water (EC = 4.91 dS m -1 ) may be an alternative for the hydroponic cultivation of coriander, despite the reduction in production, but without any damage on the visual aspect of the product. Plants grown at the initial and intermediate positions along the hydroponic channels showed higher production.Frequências de recirculação de solução nutritiva no cultivo hidropônico de coentro com água salobra R E S U M O Neste trabalho foi utilizado um sistema hidropônico com os canais de cultivo em nível com o objetivo de avaliar a cultura do coentro submetida a diferentes intervalos para recirculação da solução nutritiva em interação com o uso de água doce e salobra. O experimento foi conduzido em blocos casualizados com cinco repetições, em esquema fatorial 2 x 4, entre fevereiro e março de 2014. Avaliaram-se dois níveis de condutividade elétrica (CE) da água: 0,32 e 4,91 dS m -1 , além de quatro frequências de recirculação da solução nutritiva (intervalos de 0,25; 2; 4 e 8 h). Este delineamento experimental foi aplicado nas avaliações realizadas aos 10, 15 e 25 dias após o transplantio (DAT). Adicionalmente, aos 21 DAT foram estabelecidas subparcelas visando avaliar o efeito da posição das plantas (inicial, intermediária e final) nos perfis hidropônicos. É viável adotar-se recirculação da solução nutritiva a cada 8 h sem perdas de produção. O uso da água salobra (CE = 4,91 dS m -1 ) pode ser uma alternativa para o cultivo do coentro hidropônico, mesmo com reduções na produção, porém sem efeitos depreciativos à qualidade visual do produto. As plantas cultivadas nas posições inicial e intermediária dos perfis hidropônicos apresentaram maior produção.

Hydroponic Cultivation of Coriander Using Fresh and Brackish Waters With Different Temperatures of the Nutrient Solution

A large number of studies on salinity in hydroponic systems have been carried out, but few of them have evaluated the interaction between salinity and nutrient solution temperatures. Two experiments were carried out in a randomized block design from January to February (Experiment I) and June to July 2018 (Experiment II). Experiment I consisted of treatments with five combinations, as follows: unheated (control) and heated nutrient solution (NS) at a temperature of 32°C using fresh water with an electrical conductivity (ECw) of 0.3 dS m −1 , and unheated and heated NS at temperatures of 30 and 32°C using brackish water with an ECw of 6.5 dS m −1 in the main plots, with two coriander cultivars (Tabocas and Verdão) in the subplots, which were grown in the same hydroponic channel. The cultivar Verdão was grown in Experiment II in a 2 × 2 factorial arrangement, consisting of two NS temperatures (unheated and heated at 30°C) and two ECw levels (0.3 and 6.5 dS m −1). Coriander cultivation is feasible with heated NS despite decreases in shoot fresh matter production compared to the control of approximately 37% for Experiment I (cultivar Verdão at a temperature of 32°C and using fresh water) and 17% for Experiment II (temperature of 30°C and using fresh and brackish waters) at 25 days after transplanting.

RESUMOObjetivou-se com o presente trabalho avaliar o cultivo de coentro com diferentes disponibilidades de solução nutritiva e níveis de águas salobras para reposição da evapotranspiração da cultura (ETc) em hidroponia NFT (técnica do fluxo laminar de nutrientes). O delineamento experimental utilizado foi blocos casualizados com cinco repetições, em esquema fatorial 2x4, totalizando 40 parcelas. Avaliaram-se duas disponibilidades de solução nutritiva (2,75 e 5,50 L por maço de 24 plantas) e quatro níveis de salinidade da água de 0,43 (testemunha); 3,09; 6,87 e 8,53 dS m -1 . A altura das plantas, as massas de matéria fresca e seca da parte aérea do maço de plantas, das folhas e do caule foram obtidas aos 7, 14, 21 e 24 dias após o transplantio (DAT). Os tipos de águas influenciaram apenas aos 21 DAT na massa de matéria fresca da parte aérea do maço de plantas. Assim, a combinação de água doce para o preparo da solução nutritiva e águas salobras para repor a ETc pode ser uma alternativa para incrementar a produção de coentro em hidroponia. Aos 24 DAT, a maior disponibilidade de solução nutritiva (5,50 L) aumentou a massa de matéria fresca da parte aérea do maço de plantas em 30,0% em relação à menor disponibilidade de solução nutritiva (2,75 L).
