Azolla pinnata R. Brown was used as a biofertilizer for rice crop in early and late wet seasons of 1985–86. Azolla as dual crop with rice increased the grain yield significantly over uninoculated control. Incorporation of Azolla increased the yield components and grain yield higher than leaving Azolla on water surface without incorporation. Azolla incorporation with 90 kg nitrogen/ha recorded the highest plant height, tiller numbers/ hill, panicles/m 2 and 1000 grain weight and grain yield of rice.
