Influence of blue green algal inoculation on the crop yield of rice plants

Increased paddy yields due to algal inoculation were earlier reported in controlled pot and field experiments (1–8). The present communication deals with a field trial conducted in a cultivator's field at Vasudevanallur in Madras State, during November 1966 to March 1967, with ASD 5 paddy variety. The paddy cultivation in the field followed a groundnut crop.
