Abstract:
Background and Objective: Human population explosion, non-sustainable agriculture and tree logging destroy natural forests, prompting reforestation with fast growing tree species using artificial cultural methods. This study investigated the effects of cow dung and poultry droppings on the germination and early growth of Eucalyptus camaldulensis L. seedlings at the Forestry Nursery in Jos, Nigeria. Materials and Methods: Using the randomized complete block design (RCBD), laboratory-tested soil samples, poultry droppings, poultry droppings plus cow dung, cow dung alone and a control (top soil only) were used in various combinations to assess the growth parameters of E. camaldulensis (seedling emergence, plant height, number of leaves, length of leaves and stem diameter) for 12 weeks. Percentages, means and relative frequency distribution were used to analyze collected data. Results: Results indicated that poultry droppings had the highest nitrogen concentration (3.2%), cow dung (2.9%) and top soil (0.070%). Treatments with poultry droppings gave the greatest plant height, number of leaves and stem diameter (girth) followed by the mixture of poultry droppings and cow dung while top soil (control) recorded the lowest growth. Mixture of poultry droppings and cow dung produced the greatest leaf length, compared to poultry droppings, cow dung and the control, respectively. Conclusion: Thus poultry dropping is recommended as the most suitable organic manure for nurturing juvenile seedlings of E. camaldulensis in the nursery for plantation purposes.
