  1. Azolla as a Component of INM

  2. Azolla as a component of INM 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.

  3. Azolla as a component of INM HOMESTEAD AZOLLA CULTIVATION

  4. Azolla as a component of INM CHARACTERISTICS OF AZOLLA Azolla fern is “Live Nitrogen Manufacturing Factory” Harbors N fixing Cyanobacteria Anabaenaazollae. 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 40-60 kg N/ha in rice crop Azolla dual cropping enhance rice yield by 55 % and supplement nitrogen by 50 %

  5. AZOLLA RICE DUAL CULTURE Field multiplication Rice-Azolla Azolla dual with rice can save 50 % of nitrogen requirement

  6. Treatment Grain yield (q/ha) % increase over control Control 13.8 ----- 50 % NPK + Azolla compost @10t/ha 23.5 44.6 50 % NPK + Azolla dual cropping 29.5 54.5 50 % NPK + Azolla @ 10 t/ha 26.6 51.4 Azolla dual cropping 22.3 41.4 100 % NPK 25.2 49.1 Azolla as a component of INM AZOLLA DUAL CROPPING WITH RICE AZOLLA DUAL CROPPING ENHANCE YIELD BY 41 PER CENT OVER NO AZOLLA TREATMENT

  7. Azolla as a component of INM Azolla success story of S E Asia Azolla Collection Azolla Collection NATURAL BLOOM Selling at market Collecting on dykes Transportation

  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

  10. Azolla as a component of INM LET US SUM UP Azolla is an aquatic fern and it harbors nitrogen fixing Cyanobacterial symbiont Anabaenaazollae. 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. contd…

  11. Azolla as a component of INM 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
