INTRODUCTION:
Azolla is a water fern that floats on the surface of fresh water ponds, rivers, and tanks in tropical and subtropical region. Its size is typically 1-2.5 cm in diameter. It belongs to a derived group of ferns Azollaceae and is closely related to several other aquatic taxa such as Salvinia and Marsilea.
NEED OF PROJECT :
In Vigyan ashram, for multiplication of azolla, different factors such as light intensity, temperature and humidity, pH of water etc. Main use of azolla is fish feed for Koi and chicken. Also azolla use for composting of organic matter in vermiwash preparation.
OBJECTIVE :
To study the effect of
- Light intensity
- Temperature
- Humidity
- pH
- Azolla Production
TRIAL:
- cleaned all 5 beds and filled with water
- 10 lit water , 10kg soil , and slurry in every bed .
- 300 gm Azolla in every bed .
OBSERVATIONS :
Azolla growth after 6 days.
According to study and observation in first 3 days azolla seems green and slowly , slowly Azolla growth was also seen .
CONCLUSION:
From above experiment we observe that due to low humidity and high temp. there is adverse effect on azolla growth. Also due to high temp. affect the chlorophyll pigment and it slowly get brown. There is need to maintain the optimum humidity and temp. for good growth of Azolla .
