Abstract

The current research aimed to investigate the impact of various treatments and patch geometries on bark recovery in Terminalia arjuna. The study was conducted in an openly situated plantation of Terminalia arjuna standing trees within the Forest Product and Utilisation Department at the College of Horticulture and Forestry in Pasighat, Arunachal Pradesh. Bark extraction was performed on equal-sized trees using two different patch sizes, and various treatments were applied to promote faster bark regeneration. After three months, the healing properties of the bark were assessed as a percentage of recovered bark. The findings of the study revealed that among the different treatments, Bordeaux paste resulted in the highest bark regeneration (39.02%), followed by Bordeaux paste with plastic (36.66%) and Neem Seed Kernel Extract paste (33.39%). These treatments exhibited significantly higher bark recovery compared to the other treatments. Conversely, the control group showed the least bark regeneration (20.61%). Regarding patch geometry, there was minimal variation observed, with narrow strips (P2) demonstrating slightly higher bark recovery (39.02%) compared to broader strips (36.12%). The research provides valuable insights into suitable treatments and harvesting techniques for sustainable bark extraction in Terminalia arjuna in the North-Eastern region.

Conclusion

The research findings revealed a variation in bark recovery concerning patch geometry. On average, Terminalia arjuna exhibited higher bark recovery in the narrow patch compared to the broad patch when considering all treatments together. Notably, after a 3-month period, treatment with Bordeaux paste demonstrated significantly higher bark regeneration compared to the other treatments. Consequently, it can be recommended that the combination of Bordeaux paste treatment and narrow patches be considered for achieving enhanced bark regeneration in the context of harvesting commercial bark-yielding tree species.
