| Summary: | The study aimed to determine the growth performance and plant
adaptation of R. glutinosa (DH19) to the selected plantation
locations in Vietnam's Northern Midland and Mountainous
regions. The experiments were arranged in a completely
randomized block design and performed on three sites in Vinh
Phuc, Phu Tho, and Tuyen Quang provinces. Research showed
that DH19 was grown and developed well, gaining an average
yield of 23.9 to 24.8 tons/ha and the catalpol content from 0.72 -
0.74%. DH19 was adapted to moderate drought conditions but
severely damaged and recovered poorly in flooding. Planting
DH19 should pay attention to root sores disease (Rhizoctonia
solani) at the seedling stage and root rot disease (Fusarium sp.)
at the harvest stage. The above study results show that DH19 can
be selected for planting in Vietnam's Northern Midland and
Mountainous regions.
