1. The study analyzed the economic performance of mustard plants grown with different fertilizer treatments, including liquid organic fertilizer from rabbit urine. 2. The results showed the treatment with the lowest amount of urea (5 grams) produced the highest return on cost ratio of 3.68. 3. Using liquid organic fertilizer from 100ml of rabbit urine produced a return on cost ratio of 2.19, higher than some other treatments but lower than the treatment with the lowest amount of urea.
