Abstract

• Chromolaena odorata (L.) R. M. King & H. Robiston; which was belong to the family Asteraceae and locally known as Bezat or Jamani-chon in Myanmar. The plant was collected in Mohnyin University Campus, Kachin State from June 2022 to September 2022. The collected specimen have been taken photographs and dried at room temperature for one month. The dried samples were ground in grinder to get fine powder. Experiments using a randomized complete block design (RCBD) with five replications were carried out. This study investigated the effect of various Chromolaena suspension on the growth and development of soybean during 2022 to 2023. The seed of soybean cultivar Y15 were tested with Chromolaena suspension and experimentally studied in laboratory and pot culture. Among the five different kinds of Chromolaena suspension treatment, the Chromolaena suspension 4 gL-1 and 6 gL-1 were best for growth and development of Soybean Y15 cultivar. In pot culture Chromolaena suspension 4 gL-1 and 6 gL-1 were much more effective in enhancement of plant height and leaf area than other treatment and control. The result showed that Chromolaena suspension actually promotes the growth and development of soybean Y15 variety.
