A New Type of Biological Activators and Organic Fertilizers Used in the Growing of Medicinal Plant Calendula (Calendula officinalis L.)

The safety of plant-based food with an herbal origin is a priority for producers and final consumers these days. The interest in the high biological value of the final food products enriched with herbal ingredients is rising. We focused on the study of physico-chemical composition and antioxidant activity of two kinds of grape juice with medicinal plant addition in our study. We used 2 varieties of grapes - Welschriesling and Cabernet Sauvignon, six species of medicinal plants - Calendula officinalis L., Ginkgo biloba, Thymus serpyllum, Matricaria recutita, Salvia officinalis L., and Mentha aquatica var. citrata in our experiment. There were14 samples prepared, two of them were control samples and 12 samples were treated with medicinal plants. We tested each of the selected parameters triplicate with an interval of one week. We evaluated the results statistically in 4 levels of significance p <0,01, p <0,001, p <0,0001 and p <0,00001. The content of fructose, glucose, dry matter, density, malic acid, pH, potential alcohol, total acids, and total sugars in the treated samples was significantly lower compared to the control sample, which was probably due to the degree of dilution of grape juice with extracts gained from medicinal plants. The antioxidant effect was demonstrably higher in the samples enriched with medicinal plants than in the control samples. The highest antioxidant effect was measured in the second test in the samples with the addition of Thymus serpyllum (80.93 % - white grape must, 82.33 % - blue grape must), Calendula officinalis L. (79.29 % - white grape must, 80.49 % - blue grape must) and Ginkgo biloba (79.10 % - white grape must, 83.3 % - blue grape must). Generally, we found out that the selected medicinal plants increase the biological quality of grape juice.

MANEJO E VIABILIDADE ECONÔMICA DA IRRIGAÇÃO NO CULTIVO DE Calendula officinalis L. CATARINY CABRAL ALEMAN¹ E PATRICIA ANGÉLICA ALVES MARQUES² ¹Departamento de Engenharia Agrícola, UFV, Avenida PH Rolfs, s/n, 36570-000, Viçosa, MG, Brasil, e-mail: [email protected]²Departamento de Engenharia de Biossistemas, UFV, Avenida Pádua Dias, 11, 13418-900, Piracicaba, São Paulo, Brasil, e-mail: [email protected] 1 RESUMO O objetivo do trabalho foi verificar a influência de lâminas de irrigação baseadas na evaporação do Tanque Classe A (ECA) na produtividade e avaliar a viabilidade econômica do uso da irrigação e adubação orgânica no cultivo de calêndula. O experimento foi conduzido em um delineamento de blocos ao acaso, com esquema de parcelas subdivididas e quatro repetições. Os tratamentos de irrigação foram: sem irrigação (0), 50%, 75% e 100% ECA e o efeito da adubação orgânica: testemunha sem adubação orgânica e adubação orgânica com esterco bovino curtido. Avaliou-se massa seca de capítulos florais, produtividade, teor e rendimento de flavonóides, custos fixos e totais de produção, receitas líquida e relação B/C. A irrigação foi viável para o cultivo sem adubação para 75 e 100% ECA e para o cultivo com adubação apenas para 50% ECA. O manejo econômico adequado é a utilização de lâmina de irrigação de 100% ECA sem adição da adubação orgânica, utilizando motor elétrico com tarifa verde.

A.MANAGEMENT AND ECONOMIC VIABILITY OF IRRIGATION IN THE CULTIVATION OF Calendula officinalis L. 2 ABSTRACT The aim of the study was to determine the influence of irrigation levels based on pan evaporation Class A (ECA) in productivity and evaluate the economic feasibility of the use of irrigation and organic fertilizer on marigold cultivation. The experiment was conducted in a design of randomized blocks with split plots and a four-replication scheme. The irrigation treatments were: no irrigation (0) 50%, 75% and 100% ECA and the effect of organic fertilization: control with no fertilization and organic fertilization with cattle manure. We evaluated dry mass of capitula, productivity, content and yield of flavonoids, fixed and total costs of production, net income and B/C ratio. Irrigation was feasible for cultivation with no fertilization for 75 and 100% ECA and for cultivation with fertilizer, only at 50% ECA. Proper economic management is the use of irrigation depth of 100% ECA with no addition of organic fertilizers, using electric motor with green tariff. Keywords: risk analysis; management of hydric recourse; water use efficiency, medicinal plant.
