Abstract : A pot experiment was conducted at the Department of Soil Science, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh from October 2021 to February 2022 to investigate the effect of cow dung and vermicompost with nitrogen on the biological growth of Aloe vera. Five treatments were used which were T1 = control (only soil), T2 = 75% soil and 25 % cow dung, T3 = 85% soil and 15% vermicompost, T4 = 90% soil, 10% cow dung and urea (30 kg ha-1 ) and T5 = 80% soil, 20% and urea (30 kg ha-1 ) having 4 replications. Plant growth and yield- relating data were collected 45, 75, and 120 days after planting. The significantly highest number of leaves plant-1 (10.25), height of the Aloe vera plant (29.12 cm), and weight of Aloe leaves (97.09 g) at harvest (120 days after planting) were obtained in treatment T2, where 70% soil and 25% cow dung were used. The above- mentioned growth parameters exhibited the lowest (leaves plant-1 , plant height and weight of leaves were 6.25, 21.5 cm 44.4 g, respectively) in control treatment where only field soil was used for pot cultivation without adding manures and fertilizers (T1). Although Aloe vera is a leafy crop and it was supposed to urea will have a superior influence on this growth, however, cow dung with very low N can perform better for Aloe vera growth. Even vermicompost performed better growth than that of urea. These results suggest that Aloe vera is susceptible to chemical urea while growing in the Dinajpur, Bangladesh environment. Further experiments should be conducted in the field at different locations for further clarification.
