Returning total wheat straw to the soil and using a specific nitrogen application method can increase rice yield. The study found that this approach led to higher rice yield compared to not returning wheat straw. The nitrogen application method called Model B was more effective than Model A in increasing rice yield. The soil nitrogen levels were also affected, with higher levels of NO3-N observed with Model B. Overall, returning total wheat straw with Model B nitrogen application can improve rice yield by increasing the number of effective earings, leading to a 9.3% increase in rice yield compared to other methods.
