Influence of nitrogen rates and harvesting time on growth performance of Eclipta alba grown on mineral soil

E. NurulNahar and H. Hanisa

Abstract
A two planting cycles study evaluated the effects of five nitrogen rates (0, 100, 200, 300 and 400 kg/ha) and four harvesting times (1, 2, 3 and 4 months after planting) on growth and yield of Eclipta alba at MARDI Headquarters (mineral soil). Eclipta alba showed optimum plant height, stem diameter, stem dry weight and leaf dry weight with application of 200 N kg/ha while 300 N kg/ha for dry root weight between 3 and 4 month after planting. Overall, optimum total plant dry weight achieved with application of 200 N kg/ha. Harvesting at three months after planting is recommended.
