“…In quail manure, a factor of 3.5 higher of this element was observed in relation to other manures. Research show that increased soil phosphorus has affected the growth of medicinal plants, such as Calendula officinalis (Moreira et al, 2005), Pfafia glomerata (Serra et al, 2011), Pimpinella anisum, Coriandrum sativum, and Foeniculum vulgare (Khalid, 2012). Another element that was superior in quail manure was potassium, being three times higher in relation to cattle and seven in relation to the organic compost.…”

Cymbopogon flexuosus is a medicinal species with relevant commercial value and widely used in flavors, fragrances, toiletries, cosmetics, soaps, detergents, and pharmaceutical products. The objective of this study was evaluate the effects of different doses and sources of two manures and one compost on plant growth, leaf nutrient accumulation, content, yield, and chemical composition of the essential oil. The sources were cattle manure, quail manure, and organic compost applied in four doses and control treatment. The species increased the growth and productions of secondary metabolites by use the manures and organic compost. The highest weight gain was obtained with fertilization between 300 and 450 g pot-1 of quail manure, but the yield of essential oil in the doses from 150 to 300 g pot-1. Overall, lemon grass plants fertilized with quail manure accumulated greater concentrations of nutrients in leaf tissue than cattle manure and compost. The neral content in the essential oil was increased with the use of quail manure compared to compost and cattle manure. The results from this study demonstrated that dose and source can alter dry weight, leaf nutrients accumulation, and essential oil content and yield.

“…A produção de massa seca de planta é utilizada para indicar a intensidade de seu crescimento e, por sua vez, o conhecimento dos padrões de acúmulo de massa seca de uma cultura possibilita melhor entendimento dos fatores relacionados com a nutrição mineral (SERRA, et al, 2011;SERRA et al, 2012). Glass (1989); Marschner (1995) e Epstein & Bloom (2006) relatam que a absorção de nutrientes influencia a taxa de crescimento da planta, tal como ocorreu com a Calendula officinalis L., pois, o aumento das doses de N aplicadas no solo contribuiu para elevar a produção de massa fresca e seca da parte aérea da planta, sendo a máxima produção de massa fresca (36,25 g planta -1 ) e seca (3,32 g planta -1 ) alcançada com as doses de N 54,6 mg dm -3 e 52 mg dm -3…”

RESUMO:O objetivo deste trabalho foi avaliar o efeito da aplicação de diferentes doses de nitrogênio no solo e de épocas de coleta sobre a eficiência nutricional do nitrogênio e a produção de biomassa em Calendula officinalis L. (Asteraceae) em condições de casa de vegetação. O substrato utilizado foi a camada de 0 -20 cm de Latossolo Vermelho Distroférrico. O delineamento experimental foi inteiramente casualizado, com quatro repetições. Os tratamentos foram constituídos de quatro doses de N (0, 21, 42 e 84 mg dm -3 ) e cinco épocas de colheita (15, 30, 45, 60 e 90 dias após o transplante). O teor de N na inflorescência de calêndula reduziu com as épocas de coleta, redução essa que ocorreu possivelmente devido à menor eficiência da absorção desse elemento pela planta e menor translocação do N para as inflorescências. Pode se concluir que as épocas de avaliação influenciaram na resposta da planta à eficiência de absorção (EFA), sendo a máxima EFA de N aos 51 dias após o transplante das mudas. Observou-se aumento na translocação de N da parte aérea (folhas e caules) para as inflorescências, tendo como consequência a redução do N na parte aérea. Houve incremento na produção de biomassa de calêndula em função das épocas de coleta , e do aumento das doses de N aplicadas no solo. A eficiência nutricional do N foi influenciada pelas épocas de avaliação e pelo teor de N presente no solo. Palavras-chave:Nutrição mineral, adubação nitrogenada, plantas medicinais. ABSTRACT:Nitrogen nutritional efficiency and biomass production in Calendula officinalis L. (Asteraceae) under greenhouse conditions. The aim of this study was to evaluate the effect of both the application of different nitrogen levels on the soil and the harvest periods on nitrogen nutritional efficiency and biomass production in Calendula officinalis L. (Asteraceae) under greenhouse conditions. The employed substrate was 0-20cm layer of Oxisol. Experimental design was completely randomized, with four replicates. Treatments consisted of four N levels (0, 21, 42 and 84 mg dm ) and five harvest periods (15, 30, 45, 60 and 90 days after transplanting). N levels in Calendula officinalis inflorescences reduced with the harvest periods, and such a reduction was probably due to the lower efficiency of absorption of this element by the plant and to the lower N translocation to inflorescences. We can conclude that the evaluation periods influenced the response of plants to uptake efficiency (UE), and the maximal UE for N was found at 51 days after transplanting of seedlings. There was an increase in N translocation from the shoot (leaves and stems) to inflorescences, which has as consequence N reduction in the shoot. Calendula officinalis biomass production increased with the harvest periods and with the increase in the N levels applied on the soil. N nutritional efficiency was influenced by both the evaluation periods and the N levels present on the soil.

The knowledge of medicinal plants is of great importance for popular health. On the other hand, the levels of secondary metabolites in medicinal plants is an important parameter to be evaluated. The study of the nutrition of plants and the production of metabolites can provide the identification of beneficial factors and also find out if there are harmful effects of this fertilization/nutrition. In this study, three experiments were carried out (nitrogen, phosphate and potassium fertilization) in the culture of Hydrocotyle umbellata L. var. bonariensis (Lam.) Spreng on dystrophic Red Latosol on metabolite production (total phenols, total flavonoids and hibalactone content). It was used the soil of a rural property in the municipality of Anápolis – Goiás (Brazil). The experimental design was completely randomized, in a controlled environment. The experiment involved the following dosages of fertilization: nitrogen (0; 30; 45; 60 e 75 kg of N.ha-1); phosphate (0; 120; 150; 180 e 210 kg of P2O5.ha-1) and potassium (0; 25; 50; 75 e 100 kg of K2O.ha-1). The maximum contents of total phenols were with the medium level of nitrogen, zero level of phosphorous and highest level of potassium. For the total flavonoid, the maximum contents were obtained with the medium levels of nitrogen and potassium and zero level of phosphorus. Finally, the hibalactone content was favored by highest level of nitrogen and zero levels of phosphorus and potassium.
