Abstract

Field trial conducted during 2014-15 at research orchard of Horticulture, College of Agriculture, Gwalior in sandy clay loam to evaluate the response of different concentration of indole butyric acid and rooting media on rooting, growth and survivability of air layers in acid lime [Citrus aurantifolia (Christm.) Swingle] var. Kagzi lime. The experiment comprising seven sources of rooting media viz., soil, soil + vermicompost, soil + cocopeat, soil + leaf mould, soil + vermicompost + cocopeat, soil + vermicompost + leaf mould and soil + cocopeat + leaf mould and three concentration of indole butyric acid (IBA) viz., 0 ppm, 1000 ppm and 2000 ppm, were laid out in factorial randomized block design with three replication. Results revealed that maximum values of callus formation (0.37 cm), rooting percentage (82.39), fresh as well as dry weight of root, growth parameter viz., number of leaves, number of new sprout /layer and survival percentage (73.61%) was obtained in soil + vermi compost + cocopeat rooting media. In case of Different concentration of IBA, highest value of all these parameters was recorded with spray of 2000 ppm of IBA.
