                  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

                               Asian countries.
More than 50 % nitrogen can be
supplemented when Azolla dual
cropped with rice.

Extensively used as biofertilizer
and green manuring for rice
cultivation                         Azolla     has   very   fast   growing
                                    character. It doubles its biomass in

      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

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
