A field experiment was conducted on rejuvenation in Kesar and Rajapuri mango trees of 42 years old during the year 2009 to 2012 with four main plot treatments (heading back) viz., 2 m (M0), 3 m (M₁), 4 m (M₂), and 5 m (M₃) from ground level and three sub plot treatments viz., 4 tertiary limbs (S₁), 5 tertiary limbs (S₂) and 6 tertiary limbs (S₃) on each secondary branch. Heading back was done in October, 2009. Results revealed that plant height, plant spread (E-W and NS), weight of fruit, number of fruits per tree and yield per tree were significantly affected by heading back treatments and maximum values were recorded in M3 treatment (5 m from ground level) in both the varieties of mango except weight of fruit, which was maximum under M2 treatment in Kesar and M3 treatment in Rajapuri. In case of tertiary branches, significantly maximum weight of fruit was observed in S1 treatment while, number of fruits per tree and yield per tree were observed in S3 treatment in both the varieties of mango, and length of fruit was observed under S1 treatment in Rajapuri variety. Interaction between heading back and new emerged branches were found non- significant in Kesar and Rajapuri varieties.
