The present study intends to experimentally evaluate the response of different levels of organic matter on growth and yield of Azolla microphylla. The study was undertaken at Plant Pathology Section, College of Agriculture, Nagpur in cement tanks arranged in Completely Randomized Design (CRD) with 10 treatments in three replications for 60 days. The treatments encompassed vermicompost 1 kg, 1.5 kg and 2 kg/tank., compost 1 kg, 1.5 kg and 2 kg/tank and FYM 1 kg, 1.5 kg, 2 kg/ tank and uninoculated control. Growth and yield parameters viz., fresh weight, dry weight, chlorophyll content, root length, frond size, heterocyst per cent, N and P per cent at 15, 30, 45 and 60 DAI were evaluated. It was observed that fresh weight, dry weight, chlorophyll content, fond size, heterocyst per cent, N per cent and P per cent were significantly higher with the supplementation of compost at the rate 2 kg/tank followed by 1.5 kg/tank and 1 kg/tank of compost. On the contrary maximum root length was recorded in 2 kg/tank FYM treatment. Treatment T10 (Uninoculated control) gave the lowest result in all growth parameters indicating the need for nutrient supplementation. It is inferred from the results of this experiment that compost supplementation at the rate of 2 kg/tank would serve as a good system for the obtaining maximum growth and yield of Azolla microphylla.
