Abstract

The study was conducted at the Fruit Nursery Farm Agriculture Extension Department, Haripur during 2013-14. To identify the most suitable time for layering in Lychee and to sort out the suitable growing medium for layering in Lychee at Haripur region. There were two factors Media (Sawdust, FYM, Silt and Garden Soil) and Time factors (10 June, 20 June, 10 July & 20 July). The data was recorded on number of days to root appearance, number of root per layer, Root length (cm), Root diameter (cm) and rooting success (%).The results confirmed that all parameters were significantly affected by various media and timing factor. Maximum number of days to root appearance (62.58), roots per layer (37.25), root length (9.43 cm), root diameter (0.25 cm), layering success (83.33%) was recorded in Silt media, while minimum number of roots per layer (26.42), root length (6.50 cm) and layering success (55.00%) was noted in Saw dust media while minimum days to root appearance (41.17), root diameter (0.17 cm) were recorded in FYM media. In case of timing factor maximum number of days to root appearance (65.75), number of roots per layer (35.58), root length (8.53cm), root diameter (0.26 cm) and layering success (85.00%) was recorded in the air layering, which were made on  20th July. The maximum number of days to root appearance (75.33), number of roots per layer (41.33), root length (10.80cm), root diameter (0.26 cm) and layering success (100.00%) was recorded in Silt media air layering made on 20 July. It was concluded that the best timing for air layering was 20th July and preferred media is silt media for Lychee propagation through air layering.
