Effect of agrotechnical factors on the yield of goldenrod (Solidago virgaurea L. ssp. virgaurea)



Content and composition of essential oil and yield of herb and seed of two Polish sweet basil cultivars (‘wala’ and ‘Kasia’) were analyzed. In 2005 and 2006 the field experiments were conducted in order to investigate usefulness of basil cultivars in two different loca- tions (mikkeli, Finland and Poznań, Poland). the weather conditions were similar in both locations in the period from transplantation to full flowering. the biomasses developed similarly. in addition, the shorter growing season in Finland is not favorable for the seed development and seed production of basil. the chemical composition of basil oil was al- most identical in both experimental sites. two newly bred Polish basil cultivars performed stable growth and good quality characters. the morphological and chemical features were almost identical, even one plantation was conducted 1000 km up to the north.
