Abstract

Sewage sludge (SS) is a source of nutrients, and it improves the physical, chemical, and biological properties of soil, thereby increasing crop productivity. Accordingly, this study was aimed to evaluate the growth and development of the silver vase bromeliad (Aechmea fasciata) cultivated in a substrate with different doses of SS. To accomplish this, silver vase bromeliad plants were cultivated for 120 days in pots containing pine bark as a substrate with varying doses of solid SS (0, 18, 36, 54, or 72 g SS L−1). The experiment was carried out in a completely randomized block design, comprising five treatments and four replications, with four plants per pot, totaling 80 plants. Substrate fertilization with SS improved the nutritional status as well as the physiological and morphological parameters of the silver vase bromeliad. Fertilization with 72 g SS L−1 added to pine bark resulted in the best outcomes for plant height and the number of leaves. [ABSTRACT FROM AUTHOR]

Abstract

The genus Rhipsalis is being cultivated as a potted plant since the view of the pendant branches with coloured flowers and fruit is very appreciated. Considering that there is no information about the production of rooted propagules of these species, the goal of this work was to evaluate the development of stem cuttings, stimulated by the application of plant growth regulators. The indolebutyric acid (IBA) was tested at 0; 4.07; 5.81, and 11.63 mmol L-1 and the naphthaleneacetic acid (NAA) at 0; 4.53; 6.47, and 12.94 mmol L-1 for their activity in promoting roots on apical stem segments of Rhipsalis grandiflora Raw. The base of stem cuttings was dipped into auxin solutions mixed with talc and each one was partially embedded in fir bark (Pinus sp) and fern fiber (1:1) in polystyrene propagation flats, placed throughout the rooting period in a greenhouse (50% shading), at 60-90% of relative humidity and temperatures from 20 to 25ºC. The experimental design was a completely randomised with eight treatments (twelve replicates), with samplings at 0; 20; 50; 80, and 150 days. The results indicate no differences between IBA and NAA regarding the dry mass of roots, but an increase in for concentrations of 0 and 4.07 mmol L-1 of IBA and 0 and 4.53 mmol L-1 of NAA, in relation to treatments with auxins. Stem cuttings treated with 4.07 mmol L-1 of IBA and 4.53 mmol L-1 of NAA, had greater dry mass of shoot bud differentiation in relation to those treated with 0 mmol L-1.

Abstract

Made available in DSpace on 2022-04-28T19:28:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-06-01 The residual sludge is a contaminating waste, coming from the urban waste treatment process. Its final disposal can become a problem when it is discarded incorrectly, generating serious environmental and health problems. However, it has a high content of organic matter, macro and micronutrients, and can be used in forest plantations as a fertilizer supplement or soil conditioner, being an interesting alternative to its final destination and recycling. Forestry is characterized by providing raw materials for the development of various products based on planted forests. In this context, the eucalyptus crop stands out due to the great importance for Brazilian economy, with an expressive increase in its plantation area in the last decades. Therefore, due to the environmental problems that can be caused by the deposit of residual sludge in the environment, this work aims to diagnose the state of the art of the use of residual sludge in the eucalyptus crop.

Abstract

The aim of this study was to evaluate the effect of urea fertiliser on the bromeliad, Aechmea fasciata. Plants were submitted to weekly treatments with a solution of 0.0, 0.5, 1.0, 1.5 or 2.0 g urea L-1. After 210 days of the experiment, biometric variables of growth and development of the root and shoot systems were analysed, together with foliar levels of chlorophyll a and b, and of carotenoids. The experimental design was of randomised blocks with four replications; eight plants were used per plot. The data were submitted to regression analysis. The highest values for chlorophyll a and carotenoid content were obtained at a concentration of 1.23 g L-1 urea, and for chlorophyll b at a concentration 1.75 g L-1 urea. Plants of A. fasciata submitted to a solution with no nitrogen showed marked chlorosis of the leaves and reduced growth and development. The mean value for the maximum levels of photosynthetic pigments was 1.40 g L-1 urea, and this can be used as an indicator of the nutritional status of nitrogen in the species. From the results, an application of 1.46 g L-1 urea to the tank in A. fasciata is recommended, as this gave the greatest accumulation of total dry weight and an increase in the number of leaves. RESUMO Objetivou-se avaliar o efeito da fertilização com ureia na bromélia Aechmea fasciata. As plantas foram submetidas aos tratamentos com as soluções 0,0; 0,5; 1,0; 1,5 e 2,0 g ureia L-1, aplicadas semanalmente. Após 210 dias de experimentação, foram analisadas as variáveis biométricas de crescimento e desenvolvimento dos sistemas radicular e aéreo, e os teores foliares das clorofilas a e b, e carotenoides. O delineamento experimental foi em blocos casualizados com quatro repetições, oito plantas por parcela, sendo os dados submetidos à análise de regressão. Os maiores valores de teores de clorofila a e carotenoides foram obtidos na concentração 1,23 g L-1 de ureia e de clorofila b na concentração 1,75 g L-1 de ureia. As plantas submetidas à solução com omissão de nitrogênio apresentaram acentuada clorose das folhas e diminuição do crescimento e desenvolvimento de A. fasciata. A média dos teores de máximos dos pigmentos fotossintetizantes foi de 1,40 g L-1 ureia, podendo ser utilizada como indicadora do estado nutricional de nitrogênio na espécie. Os resultados obtidos permitem recomendar a aplicação no tanque de 1,46 g L-1 de ureia em A. fasciata, uma vez que possibilitou o maior acúmulo de massa de matéria seca total e aumento no número de folhas.
