The study looked at how different amounts of compost and nitrogen fertilizer affected maize yield. They found that using 10 tons of compost and 105 kg of urea fertilizer per hectare resulted in the highest grain yield of 11.3 tons per hectare. This combination gave a 63% higher yield compared to not using any compost or fertilizer. The researchers recommend using 10 tons of compost and 105 kg of urea fertilizer to improve maize yield in similar areas.
