Application of urea significantly enhanced the growth and biomass production in Terminalia arjuna seedlings

Terminalia arjuna, a deciduous tree native to the Indian subcontinent, is highly valued for its medicinal properties, particularly its cardioprotective and antioxidant effects. Its high nitrogen content makes it an exceptional natural source of this essential nutrient for plant growth. The current study aimed to assess the impact of urea fertilizer on the growth and photosynthetic parameters of T. arjuna seedlings. A pot experiment was conducted at the Department of Forestry and Range Management, University of Agriculture Faisalabad, using a completely randomized block design with five treatments and four replications. After 15 days of transplanting, urea fertilizer was applied to all pots at the recommended dose. Growth attributes measured included stem diameter, plant height, number of leaves, and root length, along with chlorophyll content. The results demonstrated that urea application significantly improved all measured growth attributes and chlorophyll content, aligning with previous research on various plant species. This research underscores the beneficial role of urea in promoting the growth and development of T. arjuna seedlings, contributing to the broader understanding of urea's impact on plant physiology across diverse species.
