A study on the effect of seed propagation techniques measures on the growth and development of Bacopa monnieri (L.) Wettst. at the nursery stage

Abstract

The study aims to determine suitable technical measures for propagating Bacopa monnieri from seeds, serving as a basis for perfecting the technical process of propagation and cultivation of this species. Research results on propagation from seeds showed that treatment formula of soaking seeds in 54°C warm water for 120 minutes and incubating until the seeds cracked before sowing shortened the germination time, increased germination speed, and yielded the highest germination rate of 51.67%, with an outplanting index of 11.24%. The growing medium consisting of soil + carbonized rice husk + bio-organic fertilizer (2:1:1) resulted in an outplanting rate of 42.67% and an outplanting index of 9.4. Sowing on February 15th in the Winter - Spring season and May 15th in the Summer - Autumn season provided the best nursery results, with germination rates reaching 45.67% - 54.0%.
