INFLUENCE OF BLUE GREEN ALGAE ON GROWTH, YIELD COMPONENTS AND ECONOMY IN LOW LAND RICE

Abstract

Studies on the effect of soil application of a composite culture inoculum of blue green algae on N economy in low land rice indicated that application of 75 kg N per ha along with soil application of composite culture of blue green algae at 10 kg per ha at 10th day after transplanting recorded higher grain yield. It was found significantly superior over the application of 75 kg N per ha alone and statistically on par with the application of recommended level of 100 kg N per ha. Thus, the blue green algae inoculation paved a way of saving of 25 per cent recommended level of fertilizer N in lowland rice.
