Abstract
Blue-green algae (BGA) are known to contribute up to 80 kg N/ha per season in the rice ecosystem (Kannaiyan et al., 1983). However, due to heavy use of N fertilizers and high temperature prevailing during rice cultivation in the Punjab, BGA technology could not be popularized. Therefore, there is a need to obtain local efficient strains and to study the effect of BGA substitution with N fertilizers at various growth stages of rice and also to test their efficacy in basmati rice which requires a lower input of N fertilizer and is sown in the month of July when the temperature is lower.
