Mean table shows that maximum number of roots plant was recorded in plants at 5cm of bark removal. The bark removal significantly influenced the number of roots plant.It indicated that the highest number of roots was observed when 5 cm bark removed. In this case an optimum area has been exposed for root development and thus resulted a high number of roots plan. The remaining three bark removal sizes 2 cm, 3 cm and 4 cm are statistically similar to each other. As for as interaction effect, significant variation in root plant-1 was observed and the highest number of roots plant were produced by cultivar Baincullela at 5 cm bark removal. The Cultivar Coratina at 3 cm bark removal was observed with the lowest number of roots plant
