Abstract:
A field experiment was conducted by the Department of Forestry, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh, during the 2023-2024 period to investigate the effectiveness of different season on resin tapping method and application of ethephon, a resin enhancer, in maximizing resin yield from Sal (Shorea robusta) trees in the Gariaband district of Chhattisgarh. The study focused on mechanical and chemical tapping techniques across different season during the winter and summer seasons. The mechanical methods employed included square, V, and hole-shaped incisions, while the chemical method utilized different concentrations of ethephon (10%, 20%, and 30%). The results demonstrated that resin yield significantly varied depending on the tapping method, tree diameter, and seasonal temperature fluctuations. The highest yields were observed in the summer season, with the square cut method proving most effective among the mechanical techniques. The application of ethephon markedly increased resin production, especially in the largest diameter class (60-75 cm) during the summer, with a maximum yield of 323.5 g/tree using a V-shape cut combined with 30% ethephon. This research provides valuable insights into improving resin extraction practices, emphasizing the importance of selecting appropriate tapping methods and optimizing chemical treatments to enhance resin yield sustainably. The findings contribute to the economic viability and environmental sustainability of resin tapping in the Chhattisgarh region.
