The present study was carried out in 2018- 19 to find the most appropriate time of inarching in jackfruit. The experiment ware laid out in one factorial randomized block design and was replicated four times. The experiment was consisted of 12 dates of inarching from February 2018- January 2019. The results obtained from the experiment revealed that the inarching performed in the month of July recorded the highest survival percentage (93.80%), length (8.55 cm) and diameter (5.80 mm) of new growth, number of primary branches (3.47), number of leaves (9.37), length of primary roots (32.84 cm) and dry root: shoot ratio (0.70) at 90 DAG, However, the maximum length of tap root (15.85 cm) and fresh root: shoot ratio were noted during the November (0.72) inarched plant. From the present finding, it can be concluded that under Tarai conditions of Uttarakhand inarching performed during July is the most suitable time for quality production of jackfruit plants of cv.
