Abstract The present study entitled “Effect of different potting media and plant growth regulators on the growth and establishment of Rangpur lime and Australian sour orange root stock seedlings.†was carried out at AICRP on Fruits, CRS, Tirupati, during year 2014-2015. The experiment was laid out in randomized block design replicated thrice with two components as effects of different potting media and growth regulators on Rangpur lime and Australian sour orange seedlings. In potting media experiment the results indicated that Rangpur lime and Australian sour orange rootstock seedlings recorded maximum plant height, number of leaves per seedling, stem girth, length of tap root, number of secondary roots per seedling, canopy spread, leaf area per seedling, SCMR, leaf dry weight, root dry weight and total dry weight of plant were recorded in the potting media containing Soil, Sand, Vermicompost @ 1:1:1 v/v, AM, Trichoderma reesei (TCT-10) @ 5g/bag each per bag. However, maximum number of fibrous roots per plant was recorded in potting media with Soil Pressmud + Vermicompost @ 1:1:1 v/v + AM [5g] for Rangpur lime rootstock seedlings. Whereas maximum number of fibrous roots was noticed in the potting media with a combination Soil, Sand, Vermicompost @ 1:1:1 v/v, AM, Trichoderma reesei (TCT-10) @ 5g/bag each per bag. Minimum growth parameters were recorded when soil, sand, FYM @ 1:1:1 v/v was used as potting media for both rootstocks. Among different growth regulators tested, to enhance the growth of Rangpur lime and Australian sour orange rootstock seedlings spraying with GA3 @ 200 ppm recorded maximum plant height and SCMR values. Whereas, highest number of leaves per seedling, stem girth, canopy spread, leaf area per seedling, leaf dry weight per plant and total dry weight of plant were recorded when plants are sprayed with IAA @ 150 ppm. Maximum root growth parameters were Name of the author : A.

R HORTICULTURAL UNIVERSITY Year of submission : 2015 recorded in the IBA root dipping treatments. Longest length of tap root and number of fibrous roots were recorded when IBA @ 250 ppm was sprayed followed by spraying IAA @ 150 ppm. Number of secondary roots and root dry weight per seedling were found highest with IBA @ 750 ppm followed by IAA 150 ppm. Lowest values per these parameters have been recorded in control for both the rootstocks. It can be concluded by the present study that from the results recorded in the present study, it can be concluded that the potting mixture containing Soil + Sand + Vermicompost @ 1:1:1 v/v + AM [5g] and Trichoderma reesei (TCT-10) @ 5g/bag was best potting media for both Rangpur lime and Australian sour orange seedlings grown in the poly bags. All the growth parameters studied except root parameters were maximum with IAA sprays. Root parameters were highest with IBA dipping in both the root stocks. Highest net monitory returns obtained from the treatment Soil + Sand + Vermicompost @ 1:1:1 v/v + AM [5g] and Trichoderma reesei (TCT-10) @ 5g/bag with higher benefit ratio in potting media experiment in both rootstocks. In growth hormonal experiment highest net monitory retunes was observed in the treatment IBA @ 750 ppm.
