Why this Research?
Chukrasia tabularis and Aphanamixis polystachya both
are native Endangered Species.
C. tabularis is irregular seed producer.
Aphanamixis polystachya is a IUCN Red Listed Threaten
species

Objectives To investigate survival percentage of two endangered species C.
tabularis and A. polystachya seedlings.
To measure the growth performance of C. tabularis and A.
polystachya seedlings at three altitude of the hill at Chittagong
University Campus.
To investigate fertilizer effect on survivability and growth
performance of two endangered species C. tabularis and A.
polystachya.

How this Research carried out?
• Randomized block design were followed in this experiment, with three
replicates in three altitude each containing 3 plots.
• There were 28 trees in each plot spaced at 2m x 2m. Two boundary rows of
the same species were planted surrounding the experiment. Planting holes
were dug by spade.

Recommendation
The results depicts that growth performance of C. tabularis and A.
polystachya is better in lower altitude of the hill. Therefore, these two
species recommended for future planting at the lower altitude of the hill
at Chittagong University Campus.
