Abstract

In Agronomic studies on individual and integrated application of Blue Green Algae (BGA) biofertilizer with graded levels inorganic nitrogen under field conditions and possible utilization of these organisms to meet at least a part of the nitrogen requirement of rice were carried out during Kharif season at agriculture research station of Nawabganj, Bareilly, India. Application of BGA @ 12.5 Kg/ha in combination with 80 Kg/ha as urea recorded favourable results in the two rice varieties (Jaya & Sarju-52) and it is comparable with grain yield, chlorophyll and protein content at recommended doses of 160Kg/ha. Thus, it may be concluded that the use of biofertilizer (blue green algae) in rice crop can save at least 40 Kg/ha/year with increased yield.
