Abstract: The purpose was to determine whether organic or inorganic fertilizers showed the best results for growing legumes in a controlled environment. Field trials were conducted on soil pH, broad bean yield and dry mass using organic and inorganic fertilizers at the greenhouse located at Graceland University. The fertilization treatments consisted of T1, Osmocote Smart-Release Plant Food T2, Dr. Earth Vegetable & Herb Fertilizer with a 5-7-3 Nitrogen, Phosphorus, Potassium ratio derived from fish bone meal, feather meal, kelp meal, alfalfa meal, soft rock phosphate, fish meal, mined potassium sulfate and a control T3. A higher number of legumes per plant (25.45) and plant height (30.48 cm) were obtained from the inorganic fertilizer (T1) than other treatments. Fruit yield and diameter were found statistically significant. No significant difference was observed in the quality of legumes in all 3 treatments. pH of the soil was improved by the application of organic manure (T2).
