 ABSTRACT

In the current scenario of agriculture, agrochemical responsive crop cultivation has become common practice, to reap high produce from farming. However agrochemical usage is not a sustainable approach and also excessive use will deleteriously affect the environment. To combat the harmful effects of agrochemicals, there is a need to develop alternate organic or integrated approaches, compost tea being one such approach. To evaluate beneficial effects of compost tea on growth and yield of paddy we implemented compost tea treatments on four genotypes (ARB 6, BR2655, HR12 and KRH 4) of paddy in a field experiments under aerobic cultivation in the Kharif of 2017 at GKVK, Bangalore. The results showed that, there is a significant increase in plant height, number of productive tillers, chlorophyll content, plant biomass and grain yield both aerated and non-aerated compost tea treated plants than control plants. From the biochemical analyses show a significant induction of defense related enzymes such as Peroxidase and Superoxide dismutase in compost tea treated plants compared to controls. This increased defense related enzyme activity suggests that compost tea can play a role in inducing defense and thus can be potentially used in disease management in paddy. Collectively, these results suggest that compost tea can be a promising eco-friendly and an effective technology for increasing yield in paddy.
