Effect of Budding Height on Success of Patch Budding in Aonla (Emblica officinalis Gaertn.)

The present investigation was carried out on one year old aonla rootstocks which were grown into 5×10 inch size black polybags in 2023 at Main Experiment Station of Horticulture, ANDUA&T Kumarganj Ayodhya. The experiment was laid out in Randomized Block Design comprises five treatment combinations consisting 5, 10, 15, 20 and 25 cm budding height from the ground level. The 15 cm height was treated as control. The observations were recorded on days taken for sprouting of bud, survival of buds after 15 DAB and 30 DAB, total sprouting, total died sprouts, total sprouts survival, length of sprout, Diameter of scion, number of determinate shoots, plant height, diameter of rootstocks just below union, diameter of scion just above union, number of leaves on determinate shoots and leaf chlorophyll content. Minimum days for bud sprouting (15.86 days), scion-shoot died percentage (0%) and maximum survival percentage (100%), total sprouting (90%) and total sprouts survival (100%) observed when patch budding was done at 25 cm budding height. Maximum length (81.56 cm) of sprouted shoot and diameter (6.03 mm) of scion, number of determinate shoots (85.05) and plant height (106.56 cm), rootstocks diameter (10.95 mm) just above union, diameter (7.53 mm) of scion just above union and number of leaves (92.52) were also recorded at 25 cm budding height. The total leaf chlorophyll content (3.31 mg/g) was found to be maximum at 25 cm budding height. It is concluded that the 25 cm budding height found to be the best for the propagation of aonla using patch budding in the month of June under North India condition on the one year old rootstocks grown in the polybags of 5×10 inch size.
