Preliminary aspects concerning the introduction into crop of the Dracocephalum moldavica L. (Moldavian dragonhead) species under the environmental conditions of NIRDPSB Brasov

Abstract

The researches are carried out within the research project ADER 2.4.1., during the years 2015-2018, a project coordinated by SCDA Secuieni and to which NIRDPSB Brasov is partner. The overall objective of this study is to introduce in crop a valuable medicinal species from Lamiaceae family, respectively Dracocephalum moldavica L. (Moldavian dragonhead) species. This objective resides from the growing concerns of consumers about nutrition, preservation of a proper health status, from the increased responsability for maintaining and protecting the environment. Originally from Central Asia and acclimatized in Central and Eastern Europe, the Moldavian dragonhead is traditionally used for medicinal purposes worldwide, for its sedative and analgesic properties, but also as a good anti-rheumatoid, antitumoral, antimutagenic, antiseptic and antioxidant. It was followed the establishment of multiplication way, the seed norm/ha, the optimum sowing time and the optimal nutrition space, in order to establish a crop technology adapted to the environmental conditions of Bârsa county. To determine the optimum sowing time was set up a single factor experience of five variants and three repetitions. For determining the optimal nutrition space of the plant was established a bifactorial experience of nine variants in three repetitions. At each variant / repetition, biometric measurements were made on the plants, and the fresh and dried herba production was also evaluated. The results were subjected to the statistical analysis, so that the best variants were highlighted, depending on the experience set up and its purpose. The contribution with new information on the crop technology of Dracocephalum moldavica L. species leads at the enrichment of knowledge in this field, as the information in the literature is more geared towards studying the species in terms of active principles in the plant, rather than crop technology.
