Production Technology of Blue Green Algae

Abstract

Blue-green algae (BGA) is a prokaryotic phototrophic organism capable of fixing nitrogen in the atmosphere and commonly used in agricultural fields for fertilizer, particularly in paddy fields. In addition to their ability to fix nitrogen, they are used with a variety of adsorbents to preserve soil fertility and other productivity-boosting soil components while also promoting crop growth. The current study demonstrated the various technologies used in the production of blue-green algae, its application and the impact of BGA on the growth and yield of paddy crops. Plants treated with inorganic fertilizers (N, P, K) produced lower yields and lowered growth attributes compared to the treatment (T₄) combined with NPK+BGA. Under these circumstances, the grain and straw yield increased by 22.2% and 28.9%, respectively, compared to the control (T₁).
