The study looked at how shading and nitrogen fertilizer affect wheat growth and yield. They found that moderate shading can increase wheat leaf area and chlorophyll content, but too much shading decreases photosynthesis. Proper nitrogen application can help wheat compensate for low light conditions and improve yield. However, excessive shading reduces the benefits of nitrogen fertilizer. Overall, the research suggests that adjusting nitrogen levels can help wheat plants adapt to different shading conditions and improve their productivity in fruit-wheat intercropping systems.
