Litchi (Litchi chinensis Sonn.) is one of the major crops of India having high demand both in domestic and international market. Availability of genuine planting material at low cost is one of the major issues for area expansion under this crop. Currently the widely adopted method of propagation is air layering, which is practiced mostly during the monsoon season, as a result only limited numbers of planting materials are generated. The success rate of air layering is dependent upon various factors like season, hormones, physiology and environmental condition. The objective of our study was to test the feasibility of extending the time of operation of air layering based on success percentage and other growth parameters. The result of the investigation revealed a reasonable performance of all the parameters throughout the seasons, although significant higher values were noticed during monsoon season in most of the parameters. A significant (p < 0.05) highest values in terms of number of secondary root (19.50), fresh weight (1.85 g), dry weight (1.05 g) and earliest root initiation (36.00 days) were observed during the month of July. Maximum success percent (85 %) and number of primary root (10.20) were recorded during the month of August. While the maximum values for shoot length (50.30 cm), number of leaves (56.25) and root length (8.57 cm) were noticed during the month of September, March and June respectively.
