A study was conducted to see how different amounts of NPK fertilizer and vermicompost affect the growth and yield of maize plants. The best results were seen with a combination of 100% NPK and 100% vermicompost, which led to the tallest plants, the most leaves, longest cobs, and highest yield. This combination also had the highest cost benefit ratio and net profit. Using NPK with vermicompost is better for fertilizing crops and improving soil quality compared to using only fertilizers.
