Lately it is more and more emphasized the spread of biological agricultural practices and also the development of new solutions for this domain. Romania ranking as the 6th country in the European Union for its agriculture potential proved to have the appropriate potential for further developing this domain too. Also, the potential for medicinal and aromatic plant use can be further developed. The purpose of this paper is to identify new uses for medicinal plants for agricultural practices. Finally our results will pave de way to improve the quality of crops by using biological agricultural practices as an important part of sustainable agriculture. Based on the practical experience and also on a complex bibliographic study for the purpose of this research it were analysed five perennial and five annual medicinal plant species. The major characteristics were the repellent and insecticide effects based on laboratory analysis which confirm the presence of some substances acting as antagonists for insects' hormones, guts inhibitors and toxic substances. The experimental model comprises the following perennial species: Artemisia abrotanum, Armoracia rusticana, Angelica archangelica, Crisanthemum balsamita, Valeriana officinalis and the annual species: Calendula officinalis, Phacelia thamacetoides, Trigonela foenum graecum, Artemisia annua, Sinapis alba. Phonological and biometric measurements were performed for 2010 and 2011 in order to evaluate the development stages of the plants during a life cycle. The influence of potato over these perennial plants and also of these plants over potato were registered as well as the influence of annual plants for preparing the land before potato culture. In this study the effect of Trigonella foeum graecum L., is analysed for its effect in preparing the land for potato cultivation. Also, the influence of othere neighbouring plants over potato development and excellent results are for Armoracia rusticana L., Angelica archangelica L [ABSTRACT FROM AUTHOR] |
