The researchers wanted to see how different types of cow manure and cow urine fertilizer affected the growth of adenium seedlings. They tested different concentrations of cow urine and three types of manure: cow, goat, and chicken. The results showed that the type of manure used had a significant impact on the plant growth, with chicken manure combined with cow urine at 5 cc per liter of water being the most effective for adenium seedling growth.
