Determination of sowing date and the plantation method of Artemisa annua L. introduced in Cuba

[摘要] INTRODUCTION: Artemisa annua L. is a Vietnam and China-original species of medicinal interest for the anti-paludism drugs begin necessary to establish the culture conditions in Cuba. OBJECTIVE: to establish some fundamental agricultural parameters for A. annua culture. METHODS: we used the sowing method and the plantation date establishing seedbeds from December, 2006 to May, 2007; subsequently at 2 months of sowing, saplings were transplanted to plots of 1 m wide and 60 cm of distance among the plants, equivalent to 6 and 9 plants/m2 respectively. To assess the better variants the plants were harvested 4 months after transplantation, that is, at 6 months old; analyzed parameters included the height achieved at the moment of harvest and the fresh foliage yield. RESULTS: we obtained only those seedbeds processed from December to February with a good germination during a period of 10 days. Regards the growth and the yield, we determined that the great values were observed en plants cultured in December and January and where three rows of plants/plots were placed. CONCLUSIONS: this species of A. annua introduced in Cuba and adapted to Vietnamese tropical environment, under conditions where studies were conducted, supplied a big seedbeds adaptation when they are established between December and January, as well as a strong growth and yield of the biomass suitable when seedbeds are transplanted to plots under sunlight, with a population density of approximately 9 plants/m2 allowing its harvest during the vegetative stage at 6 months age with high foliage yields.
