An experiment was conducted during the rainy season of 1992 and 1993 to find out the effect of water regime, variety and biofertilizer (blue-green algae) on rice (Oryza sativa L.) yield. The results indicated that the water management practice of saturation till tillering and submergence till ripening recorded significantly higher grain yield as well as water-use efficiency (WLIE) compared with other treatments except continuous submergence system. Cultivar Kranti gave considerably more grain yield and recorded higher value of WUE than IR 36. Application of blue-green algae was found better in respect of grain yield and WUE over its control. Increase in yield by saturation till tillering and submergence till ripening, Kranti and BGA were due to the improvement in yield attributes of rice.References

The results indicated that the water management practice of saturation till tillering and submergence till ripening recorded significantly higher grain yield as well as water-use efficiency (WLIE) compared with other treatments except continuous submergence system. Cultivar 'Kranti' gave considerably more grain yield and recorded higher value of WUE than 'IR 36'. Application of blue-green algae was found better in respect of grain yield and WUE over its control. Increase in yield by saturation till tillering and submergence till ripening, 'Kranti' and BGA were due to the improvement in yield attributes of rice.

Rice productivity can be made more evaluate the effect of water regime, variety economical if water-management practice and blue-green algae on transplanted rice. is adopted judiciously. Maintenance of shallow depth of submergence after MATERIALS AND METHODS transplanting has been argued to be
conducive to higher yields (L?qka, 197 1). The field experiment was conducted at Similarly, theemain reason of low yield is Baronda Farm, Raipur (M.P.1 in the fiarif non-availability of suitable variety for a season of 1992 and 1993. The soil was
