Abstract:
Rootstocks modulate several characteristics of citrus trees, including vegetative growth, yield, quality and resistance or tolerance to different biotic and abiotic stresses. Rough lemon (Citrus × jambhiri) and Rangpur lime (Citrus limonia Osbeck) is the most promising rootstock for mandarin. Good growing medium support to the plant, serves as reservoir for nutrients and water allow oxygen diffusion to the roots and permit gaseous exchange between the roots and atmosphere outside the root substrate (Abad et al., 2002). Micro-budding is a new propagation technique and standardized in Citrus species which could revolutionize the commercial citrus industry by saving grower’s time, space and money. The experimental was consisted in Asymmetric Factorial Completely Randomized Design with three replication. Treatment includes three factors i.e. Rootstock (rough lemon & rangpur lime), growing media (Soil + Vermicompost (1:1), Soil + Azotobacter (1:1), Soil + Vermicompost +Azotobacter (1:1:1), Cocopeat + Vermicompost (1:1)) and age of rootstock (4, 5 and 6 month). On the basis of results found in the present investigation it is concluded that Cocopeat + Vermicompost (1:1) with rough lemon seedling found superior in seedling height (cm), stem diameter (mm), and survival % after transplanting in different growing media followed by Soil + Vermicompost + Azotobacter (1:1:1) with Rough lemon.
