In view of the above, the objective was to evaluate the impact of different combinations of quality and light intensity with the use of colored meshes in the absence and presence of organic fertilization in the growth and content of photosynthetic pigments of plants of ora-pronóbis. The study was carried out in a greenhouse located at the Federal University of Recôncavo da Bahia, in the municipality of Cruz das Almas-BA. The design was completely randomized in a 2 x 3 factorial scheme, arranged in subdivided plots. The combined action of the red mesh and addition of humus to the soil increased the chlorophyll and total content of the ora-pro-nóbis plants, whereas for the carotenoid content the best results were obtained in the plants grown in full sun with the presence of earthworm humus in soil.The environment in full sun provided the highest root length and the addition of humus to the soil provided an increase in the number of leaves and shoots, in the leaf area, leaf area ratio, leaf mass ratio and leaf dry matter mass, an important result, because the leaves represent the commercial product of ora-pro-nóbis. The cultivation in full sun and fertilization with earthworm humus is the most suitable for the initial growth of the ora-pro-nobis plants.
Objetivou-se avaliar as características agronômicas, índices fisiológicos e diagnose nutricional de plantas de Salvia officinalis L. cultivadas em diferentes condições de luminosidade e substratos orgânicos. O delineamento experimental utilizado foi inteiramente casualizado em esquema fatorial 4 x 4, sendo três tipos de substratos orgânicos: húmus de minhoca, esterco bovino curtido, vivatto plus® e a testemunha (solo sem adubação) e quatro condições de luminosidade obtidas com o uso de malhas: 1) malha ChromatiNet Vermelha; 2) malha Aluminet; 3) Malha Preta e 4) Tratamento controlea pleno sol. Os dados foram submetidos à análise de variância com auxílio do programa estatístico computacional "R". Observou-se efeito significativo da interação entre os ambientes de luz e os substratos orgânicos para as variáveis área foliar específica, razão de área foliar e a relação clorofila A e B. Para as demais variáveis houve efeito isolado dos substratos orgânicos e também dos ambientes de luz. O crescimento das plantas de sálvia é influenciado por diferentes ambientes de luz e substratos orgânicos. O uso do solo+esterco bovino curtido e solo+vivatto plus® proporciona maior crescimento das plantas de sálvia, enquanto que os substratos solo+húmus de minhoca e solo+esterco bovino curtido promovem maiores teores de P e K nas folhas e raízes das plantas de sálvia.
Studies on the cultivation of medicinal plants are of relevance to the population since they are primary sources of medication. Among these plants stands out the rosemary (Rosmarinus officinalis L.) for having diverse therapeutic properties. The objective of this work was to evaluate the initial growth and nutritional status of rosemary plants grown with different co’ncentrations of nitrogen and sulfur. The treatments were distributed in a 4x2 factorial scheme with four nitrogen doses: 105, 210, 315, and 420 mg L-1 of nitrogen combined with two sulfur doses: 32 and 64 mg L-1 with seven replications totaling 56 experimental units. The seedlings were obtained through asexual propagation (cuttings), originating from parent plants. The experimental units were arranged in a completely randomized design. Growth evaluations were carried out at 120 days of cultivation, using: plant height (HT) stem diameter (DS), root dry matter mass (RDM), stem dry matter mass (SDM), mass leaf dry matter (LDM), total dry matter (TDM), shoot dry matter mass (SDMS). The data obtained were subjected to analysis of variance and depending on the level of significance in the F test, the study was carried out using the means test (Tukey 5%). The agronomic characteristics (HT), (DS), (RDM) and (MDMAP) were significant for N. Only (RDM) showed significant interaction for the doses of N and S. The dose 420 mg L-1 promoted the highest concentrations in the components leaf and stem. The lowest dose 105 mg L-1, N promoted the highest concentrations of S in the leaf and stem. The assimilation of S by the rosemary plants was dependent on the doses of N.
