Study on the cultivation of some new species of medicinal and aromatic plants

Abstract

At the Agricultural Research and Development Station of Secuieni, Neamţ County, we have studied the cultivation of some new native species: Geum vulgare L (Purple avens), Origanum vulgare L. (Oregano), as well as the acclimatization of Echinacea purpurea (L) Moench. and Ocimum sanctum L. (Holy basil), due to their special therapeutic value. The studied variants have followed the determination of the best sowing period for this plant. Under the conditions of the Secuieni Station, the native species Origanum vulgare L. and Geum vulgare L., as well as the foreign species Echinacea purpurea (L) Moench. and Ocimum sanctum L., when sown at the optimum period for them, have found the best conditions of growth and development. In Echinacea purpurea (L) Moench., the highest production of dry herb (55.60kg/ha) was found at the control, compared to 1320 kg/ha dry herb (55.60kg/ha), obtained at the variant sown in summer. The yield difference was of 4240 kg/ha (24%). In Ocimum sanctum L., the highest yield of dry herb (1811.3 kg/ha) was obtained at the variants sown in the first decade of April (20-30 April) that exceeded the control (sown in the first decade of April) with a yield increase of 654.6 kg/ha (157%). Geum vulgare L. had the highest yield of fresh root (3390 kg/ha) at the variant sown at the end of summer (20-30 August), compared to only 1268 kg/ha obtained at the variant sown in spring , the difference being of 2010 kg/ha (41%). In Origanum vulgare L., the highest production of dry herb (3521.67 kg/ha) was obtained at the control sown at the end of August (20-30 August), compared to 2133 kg/ha dry herb as we obtained at the variants of the second stage. The production difference was of 1455 kg/ha (41%).
