Role of Blue Green Algae in Paddy Crop

Shah Alam, Rajendra Kumar Seth and D. N. Shukla

Cyanobacteria (BGA) are one of the major components of the nitrogen fixing biomass in paddy fields. Due to the important characteristic of nitrogen fixation, cyanobacteria have a unique potential to contribute to enhance productivity in a variety of paddy. The best known effect of blue-green algal growth on rice increased nitrogen availability resulting from nitrogen fixation but other effects have been reported. In this research BGA used as inoculum in rice experimental plot. The BGA+FYM inoculum plot effective treatment compared to the control. The 50% NPK+BGA most effective treatment compared to the recurred of rice NPK (100%). Applications of NPK, BGA with FYM produce most significantly plant height, Weight of 1000 grain, Total grain yield percentage, extra increase yield percentage, compared to the control. The 50% NPK+BGA+FYM inoculums found to be most effective treatment for the rice production.50% NPK,FYM with BGA in inocolation in rice Plot No. 5 in this plot height of rice plant 149.9 cm, weight of 1000 grain 23.833 gm and extra increase percentage yield 20.06%.
