INTRODUCTION
Azolla an aquatic fern is regarded as “Live Nitrogen Manufacturing Factory” because, it harbors nitrogen fixing Cyanobacteria.
Azolla has been extensively used both as biofertilizer and green manuring for rice cultivation in the South East Asian countries.
More than 50 % nitrogen can be supplemented when Azolla dual cropped with rice.

Azolla fern is “Live Nitrogen Manufacturing Factory”
Harbors N fixing Cyanobacteria Anabaena azollae.
Extensively used as biofertilizer and green manuring for rice cultivation
Azolla has very fast growing character. It doubles its biomass in 3-5 days
Azolla fixes kg N/ha in rice crop
Azolla dual cropping enhance rice yield by 55 % and supplement nitrogen by 50 %

8. MASS MULTIPLICATION OF AZOLLA
HOMESTEAD METHOD
Prepare pit 2m length,1m width & 20cm depth
Spread polythene sheet (2.6mx1.6m) over the pit
Add SSP (10g), MOP (10g) , dry cow dung (100g) & Azolla 300 g
Mud plastering the surroundings & pour water level (10 cm )
Multiply for 15 days. Harvest and repeat the above procedure

9. Azolla as a component of INM FIELD METHOD FOR AZOLLA MULTIPLICATION
Prepare and level the field uniformly
Divide the field into 20x5m providing suitable bunds & irrigation channel
Maintain 10 cm water depth
Add 10 kg cowdung+8kg Azolla+100 gm SSP /plot
Harvest after 15 days

LET US SUM UP
Azolla is an aquatic fern and it harbors nitrogen fixing Cyanobacterial symbiont Anabaena azollae.
Azolla has been extensively used both as biofertilizer and green manuring for rice cultivation in the South East Asian countries.
Azolla dual cropping with rice along with 50% recommended fertilizers could enhance rice yield by 55 % over control.

LET US SUM UP
More than 50 % nitrogen can be supplemented when Azolla dual cropped with rice.
Cost effective Azolla multiplication can be done both under homestead and field methods.
Azolla can also be used as organic feed supplement
