“…Kleiber et al (2012), in a research with onion (Allium cepa) grown in soil, found that magnesium nutrition with 100 mg/dm 3 resulted in 38% increase in productivity, but higher doses (150 -200 mg/dm 3 ) showed reduction of 12.5% in the commercial productivity of onions, negatively impacting productivity. The absorption of nutrients is different for each plant and the adequate dose of each nutrient is essential in hydroponics cultivation (Luz et al, 2018).…”

Chives are popular herbs, and highly appreciated by consumers. The experiment was conducted in the period from September to November 2020 in a greenhouse, located at the Federal University of Technology, Paraná, Brazil. This study aimed to evaluate the growth, physiological responses, and quality attributes of chives grown in hydroponic systems containing different concentrations of magnesium sulfate. The experimental design was randomized blocks, and the treatments consisted of a standard solution with the addition of magnesium sulfate at the following doses (g/L): standard solution 0.4; 0.42, 0.44; 0.46, and 0.48, with four repetitions per treatment. The analyzed variables were physiological indicators and growth; physical-chemical characteristics and nutrient content in tissues. The dose of 0.48 g/L resulted in the highest number of leaves (47.3) and contributed to 44% reduction in leaf drop, thereby positively influencing growth with higher fresh mass (231.40 g/plant). The relative chlorophyll index (58.64) obtained at 0.48 g/L dose revealed an increase in the chlorophyll content and, consequently, in the green color of the plants, with °hue angle of 140.54. Greener leaves is a visual aspect preferred by consumers. In addition, the higher concentration of magnesium sulfate provided 50.7% increase in the content of soluble solids and 50.6% rise in phenolic compounds. The dose of 0.48 g/L magnesium sulfate contributed to reduced leaf fall, improved visual appearance, greater bioactive compounds, and enhanced leaf sweetness to meet the quality standards that consumers expect for this condiment.

“…In traditional medicine, A. absinthium is also used as anti-parasitic and analgesic agents. Previous studies on A. absinthium resulted in the isolation of diverse components, including dimeric guaianolides, flavones, lignans and volatile oils (Turak et al 2014, Luz et al 2018. The essential oils produced by this species has different biological properties including antimicrobial, acaricidal, insecticidal, anthelmintic, antiseptic, antispasmodic, neuroprotective, and antioxidant activities (Riahi et al 2015, Li et al 2020.…”

Artemisia absinthium, also known as wormwood, is used in traditional medicine as anti-parasitic and analgesic. The aim of the present study was to evaluate the effect of four doses of mineral fertilization in two harvest times on the content and composition of the essential oils produced by A. absinthium. The tested doses of mineral fertilization were the following: without fertilization (D0); 50% of the recommended dose (D1); recommended dose (D2); and 150% of the recommended dose (D3). The plants were cultivated in 10 L pots kept in greenhouse. The samples for extracting the essential oils were collected at 60 and 125 days after transplantation (DAT). The essential oils were obtained by hydrodistillation using a Clevenger-type apparatus. Identification and relative percentage of the compounds in the essential oils were performed by GC-MS. The essential oils content varied from 0.04% to 0.41% w/w. The highest essential oil content obtained was 0.41% using the dose D3 at 120 DAT. Myrcene and Z-isocitral were the major constituents of essential oils. According to the results obtained, A. absinthium can be used as a source of myrcene, depending on the dosage of mineral fertilization used and the time of harvest.

Objetivou-se com o presente trabalho avaliar diferentes concentrações de sais na solução nutritiva proposta por Furlani (1999) em cultivo hidropônico de rúcula no sistema deep film techinique (DFT) em ambiente protegido. O delineamento utilizado foi inteiramente casualizado (DIC) com quatro repetições, sendo os tratamentos cinco concentrações de sais: 33%, 67%, 100%, 133% e 167% em relação a concentração original com adaptação do nutriente cobre na concentração 0,064 mg L -1 . As mudas foram conduzidas durante 30 dias em sistema hidropônico (DFT). Os resultados mostraram que o incremento de sais a partir da dose de 67% não apresentou ganhos significativos em massa seca. Os resultados também não apresentaram resultados significativos em teores foliares, que em concentrações altas apresentaram interação negativa entre alguns nutrientes. Para o acúmulo dos nutrientes nitrogênio, fosforo e potássio e composição centesimal nenhuma concentração de sais acima de 100% propiciou aumento efetivo que justificasse o aumento do custo inerente ao aumento dos sais na solução. O cultivo de rúcula apresenta melhor desenvolvimento com concentrações de sais entre 67 e 100 %. Palavras-chave: Solução Nutriva. Floating. Eruca sativa. Brássica. Rendimento nutricional.
