Teza

Introduction In Republic of Moldova the sage is cultivated on industrial areas around 3000ha (1). All cultivated varieties form the main harvest of raw materials in the second year of vegetation. Usually, in the fi rst year of vegetation clary sage is not blooming or insignifi cant productions rarely form. Also, for maintaining crops without weeds, a large number of manual and mechanized labors are needed or it is necessary to apply 2-3 expensive herbicides. As effi cient method was proposed clary sage association with other species that would achieve signifi cant production and justify care costs in the fi rst year of vegetation (2, 3). As associated varieties were selected annual crops like: sweet fennel and dill, which are and aromatic plants as well. The effectiveness of these combinations of crops has been the subject of studies in 2011-2013 years. Material and methods Researches had been carried out on a carbonate black earth with humus content 2.7% in the 0-20 cm layer. Dacia-50 sage variety was sown late in the autumn to distance between the rows about 70 cm and seed norm being 10 kg/ha. Sweet fennel origin Italy and” Comun” variety dill were seeded joined the ranks of clary sage at distance of 10-15 cm, forming bands with two rows. Sweet fennel was sown in early spring-time 10-12 kg/ha, and dill was sown in spring (2011) or in autumn along with clary sage (2012 and 2013). Crops were maintained weeds free by mechanical breaking 2-3 times between bands and manual breaking on rows. Results and discussions Researches has shown that clary sage control cultures has achieved an average production of 0.8 t/ha of raw material and only 1.3 kg/ha of volatile oil, which can be neglected. Fennel as attendant culture showed a production of 4.9 t/ha of raw material and 29 kg/ha of volatile oil. The early spring sown dill assure 5.3 t/ha of raw plant raw material and 47 kg/ ha of volatile oil, that is an advantageous embodiment. Dill sown in early winter with clary sage largely loses the germination of fi eld and do not provide the necessary density of plants. This leads to reduction of raw material harvest to 1.2 – 1.8 t/ha (2012-2013 years). Attendant crops do not negatively affect clary sage growth and development in the fi rst year of vegetation. Therefore the clary sage associated with dill and fennel in the second year of vegetation gave aromatic raw material equal to that of the control culture, respectively 10.2 and 10.3 t/ha. Volatile oil production in cultures variants of clary sage associated with fennel and dill is higher than at control culture, respectively 19.2-19.4 kg/ha and 18 kg/ ha at control.  Conclusions Thus, it was shown that clary sage cultivation with varieties of Apiaceae family has perspective of application in practice. Dill and fennel partially shaded clary sage and weeds stopping them from growing. This ensures a real production of associated varieties as a reward for clary sage care spending. The attendant of clary sage with Apiaceae varieties is favorable also because all agrogenesis components, as: sage, dill and fennel, are selective and tolerant to preemergent application of herbicide Prometrex (4.0 kg/ha), which may control the weeds growth.
