A study was conducted to see how using green manure and nitrogen affected maize yields and quality. Different treatments were tested, and the best results came from maize planted after green manure with 150 kg of nitrogen per hectare. This method produced the highest yield and quality compared to other treatments. Maize planted after green manure with 225 kg of nitrogen per hectare also had good results, with a slightly higher yield but similar quality. Overall, using green manure and nitrogen together can improve maize production and quality.
