Azolla is a free-floating aquatic fern and known biofertilizer for lowland rice as it fixes nitrogen from atmosphere with help of cyanobacteria, which resides exclusively in its dorsal leaf pocket. Though, it is a well established biofertilizer still it has not become popular and reaches among large farming community due to requirement of its huge primary inoculums (2-5 t/ha). Even transportation of its bulk amount for ex-situ application and maintenance leads to higher costs to the farmers. Hence, a technology has been made to reduce its initial inoculum load by developing sporocarp-based Azolla formulation. Altogether 23 strains of sporocarp-producing Azolla are identified among 102 strains of Azolla germplasm, conserved and maintained at NRRI, Cuttack round the year. Carrier-based sporocarp formulation (50 ± 10 spores/g product) is developed to reduce its bulk inoculum. This sporocarp-based Azolla technology may considerably reduce the quantity of its primary inoculum and ease the application in lowland rice production. Not Available |
