Abstract: The present investigation was carried out at AICRP on Fruits, Citrus Research Station, Tirupati, during 2016-2017 to study the Effect of organic amendments and bio-agents on growth of acid lime (Citrus aurantifolia Swingle) cv. Balaji seedlings in the nursery. The experiment was conducted in completely randomized design with three replications. The treatments consisted of 21 treatments with different potting media, organic amendments and bio-agents and their effect was studied on three age group acid lime seedlings. The results indicated that the medium combination soil, sand, cocopeat @ 1:1:1 v/v, neem cake (20g) with AM F@ 5g had given significantly better results among different combination in 2 months old seedlings. In case of three and four months old acid lime seedlings maximum length of tap root, number of secondary roots per seedling, root dry weight, leaf dry weight, total dry weight per seedlings were recorded in the potting media containing soil + sand +vermicompost + Arbuscular mycorrhiza (5g) + neem cake 20g each per bag. However, minimum growth parameters were recorded when soil, sand, FYM @ 1:1:1 v/v was used as potting media in case of 2, 3, 4 months old seedlings.
