INTRODUCTION

Azolla is a branched free-floating aquatic fern, and it rapidly grows on the water’s surface.Besides its utilization as a biofertilizer on a variety of crops, Azolla can be used as an animal feed, a human food, a medicine, and a water purifier. Azolla grows best in full to partial shade (25-50% of full sunlight). Growth decreases quickly under heavy shade (lower than 1500 lux) and more than 50% of full sunlight reduces photosynthesis. The optimum relative humidity for Azolla growth is between 85 to 90 %.

conclusion

In this experiment , we observed that trey no. 6 which contains PSB+MgSO4+FeSO4 have a double growth rate of Azolla.

In this combination fertilizers , can be used ferther for culturing ofb Azolla
