The algal symbiont of Azolla - Anabaena azollae (AS-DS) immobilized in polyurethane foam and hollow fibre recorded higher heterocyst frequency, nitrogenase activity, protein contents and ammonia excretion. Rice seedlings (ADT-36) were raised in acid washed and sterilized sand and inoculated with immobilized A. azollae increased the seedling growth.
