Effect of Blue Green Algae as Biofertilizer on Yield and Composition of Asgandh Plants

The present investigation was carried out with Asgandh (Withania somnifera) plants, raised in well mixed garden soil with @ 25, 50, 100 and 200g blue green algae (BGA)/kg soil treatment, On the basis of estimated values the maximum yield of 25 days old tops were observed at 200 g-BGA/kg-soil treatment, which was highly significant over control. Regarding catalase and peroxidase activity there was significant increase at 50 gBGA/kg-soil level and chlorophyll and ascorbic acid content at 200 g-BGA/kg-soil treatment as compared to control. There was significant decrease in catalase, peroxidase chlorophyll and ascorbic acid contents with further increase in BGA level as biofertilizers.
