Trial first

Objective of trial: To know growing period for azolla and required climatic condition for growth.

Dimension of tray:

Length = 42 cm, Width 32 cm

Area of tray = L × W

                                 = 42 × 32

                                 = 1344 cm2 (0.13 m2)

Azolla well grown after two days it has been doubled its bio mass after 4 days. Near about 90% area of trey was covered by azolla after 4 days.

Result:

Understood the climatic requirements and growth period of Azolla
