RESEARCH ON EFFECTS OF PLANTING AND HARVESTING TIME ON MEDICAL YIELDS OF ELEUTHERINE BULBOSA MILL. URBAN IN THANH HOA

Abstract

   Experimental design of growing season, harvesting season of Eleutherine bulbosa (Mill.) Urb., by RCBD field experiment, 3 replications was carried out. Planting seasonal experiment consists of 6 formulas (Growing in October, November, December, January, February, and March) and harvested time experiment consists of 3 formulas (harvesting 330 days after planting, 360 days after planting 390 days after planting).
