Seeds of Ipil-Ipil imported from the Philippines were experimentally
tried at Charaljani (Tangail) and Keochia (Chittagong) to compare
the growth performance of the cultivars.

Survival percentages of the three cultivars, K8, K27 and K67 at
Charaljani were 96, 94 and 93 respectively, whereas at Keochia they were
89, 75 and 80 respectively. Height growth at Charaljani was almost
double that at Keochia. The height growth after 140 days at Charaljani
was 63.5 cm, 35.5 cm and 38 cm for K8, K27 and K67
respectively. The above-ground biomass (green weight basis) in 9
month old trees was 11.34 Kg for K8, 9.97 Kg for K27 and 9.0 Kg. for
K67 at Charaljani. These figures were better than those at Keochia.
The plots at Keochia were, therefore, abandoned later.
