Different Doses

In the present work the effect of natural biostimulators and different doses of slow disintegrating fertilizer on the quality of rosemary seedlings was studied. Rosemary seedlings were produced in containers, according to the 'speedling system'. During the production of seedlings natural biostimulators Megafol and Viva and microbiological fertilizer Slavol were added. The applied biostimulators made a significant effect on the quality of rosemary seedlings. Different doses of the slow disintegrating fertilizer Scotts (Osmocote Extact) were applied (0, 1, 2, 3 and 4 g/l), which also produced a significant influence.

A relevant improvement of the cultivar conditions of Rosmarinus officinalis L. in desert areas was achieved by a specific combination between an irrigation system and soil conditioner. A drastic reduction in water employment was obtained without affecting the quality of the plants, which was determined by monitoring the growth parameters and essential oil characteristics. In particular, the effect of surface and subsurface drip irrigation systems and different soil conditioners on the growth parameters, yield, and essential oil constituents of rosemary plants was assessed. Field experiments at the Agricultural Research Station (Al-Adlya farm), SEKEM Group Company, El-Sharkiya Governorate, Egypt, conducted over the two seasons, revealed the effectiveness of subsurface irrigation systems in obtaining better performances, especially in terms of saving water. The combination of subsurface irrigation and the conditioner HUNDZ soil with bentonite showed the maximum mean values of growth characteristics compared with other soil amendments during both seasons. The possibility to employ a water-saving irrigation system at the subsurface level without any drawback in the resulting plants was also explored in terms of molecular composition. Gas chromatography-mass (GC-MS) analysis of the essential oils extracted from plants grown under different irrigation conditions revealed a comparable composition in both cases. The quality of the system that showed the best performance was also confirmed by the comparable yield of the essential oil.

The objective of this work was to evaluate the influence of homeopathic preparation Arnica montana in rooting of Rosemary (Rosmarinus officinalis) and White Lippia (Lippia alba). The cuttings Rosmarinus officinalis and Lippia alba, collected from the medicinal garden at NCA / UFMG, were placed in trays to root with commercial substrate type "plantmax" and immediately after were subjected to daily applications of homeopathic preparations of Arnica montana in dilutions 3cH, 6cH, 9cH, 12cH, with 2 controls, distilled water and ethanol 70%. The statistical design was completely randomized (DIC), with 6 treatments and 4 repetitions, each experimental unit was formed by 10 stakes. After 45 days, were assessed the number of roots, the nummber of shoots, the length of the largest root, the percentage of rooted stakes and the quality of stakes. Arnica montana in dilutions 3cH, 6cH and 12cH stimulated all variables related to the issuance of roots in the species under study, which emphasizes the similarity between Arnica montana and the picture elicited by the physiological process of cutting, promoting an increase in the percentage and quality of the roots.

Mudas de Rosmarinus officinalis e Lippia alba, cultivadas no horto medicinal de NCA/UFMG foram colocadas para enraizar em bandejas contendo substrato comercial de tipo "plantamax" e imediatamente após, submetidas a aplicações diárias de preparados homeopáticos de Arnica montana nas diluições 3cH, 6cH, 9cH e 12cH, com dois controles, água destilada e etanol 70%. O desenho estatístico foi completamente randomizado (DIC), com 6 tratamentos e 4 repetições, cada unidade experimental esteve composta de 10 estacas. Depois de 45 dias, foram avaliados o número de raízes, o número de brotos, a longitude da raiz mais longa, porcentagem de estacas enraizadas e qualidade das estacas. Arnica montana nas diluições 3cH, 6cH e 12cH promoveu todas as variáveis relacionadas com a formação de raízes sob estudo, acentuando a semelhança entre Arnica montana e o quadro induzido pelo processo fisiológico do estacamento, promovendo aumento na porcentagem e qualidade das raízes.

Rosemary production (Rosmarinus officinalis L.) in Colombia is destined mainly for international markets (2.898 t in 2006), Although the national demand is low, this is a promising crop in some areas of the country, having potential to enhance producers life quality through the implementation of sustainable crops allowing the decrease of non-beneficial conditions in agriculture labors. Studying the response to the application of biofertilizers as an alternative to implement rosemary organic crops has become an important tool for the integrated crop management. In this research three commercial biofertilizer applied to the soil were evaluated (Azotobacter chroococcum, Pseudomonas fluorescens, humic and fulvic acids) facing a control treatment, significant differences were found regarding the number of stems growth per plant, however variables as oil extract volume and plant height did not present significant differences when compared with control treatment.

Rosmarinus Officinalis L

The extraction of essential oils is generally carried out by two main techniques: azeotropic distillation (hydrodistillation, hydrodiffusion, and steam distillation) and extraction with solvents. However, these traditional methods are a bit expensive, especially since they are extremely energy and solvent consuming. This work consists in studying two methods of extraction of the essential oils of Rosmarinus officinalis L.: microwave assisted hydrodistillation (MAH) and Clevenger hydrodistillation (CH). Several parameters have been studied: the extraction time, the yield, and the chemical composition of the essential oils as well as the efficiency and cost of each procedure. The results obtained revealed that microwave-assisted hydrodistillation makes it possible to minimize the extraction time of the essential oils in comparison with conventional hydrodistillation. Thus, the same yield of essential oils is obtained for 20 minutes only with MAH while it takes 180 minutes with CH. In addition, the quality of the essential oil is improved thanks to a 1.14% increase in oxygenates. In conclusion, the MAH method offers significant advantages over conventional hydrodistillation and can therefore replace it on a pilot and industrial scale.
