Supporting evidence — 5 representative gaps

• Interspecific competition and productivity in a dryland silage maize/alfalfa intercropping system (2023) · Food and Energy Security · cited 11× · doi

  Abstract Cereal–legume intercropping has the potential to reduce the use of nitrogen (N) fertilizer and increase forage yield and quality, however, how to optimize system design to fully realize interspecific complementary and enhance crop production in an annual and perennial crops intercropping was not well understood.

• Biochar-biostimulant combinations enhance nodulation, yield, and antioxidant defense in mungbean under reduced NPK fertilization (2026) · Scientific Reports · cited 1× · doi

  One challenge is the need to reduce mineral fertilizer inputs while maintaining crop productivity. Another challenge is the potential for nutrient limitation, reduced photosynthetic performance, and oxidative imbalance in plants under reduced NPK supply.

• Sustainable Intensification of Feed Production Through Intercropping of Cereals and Legumes: The Role of Nitrogen Fertilization in Shaping the Circulation of Micronutrients (2026) · Agriculture · doi

  The study identifies the challenge of reducing mineral nitrogen inputs in agriculture while maintaining nutrient use efficiency and feed quality. The research highlights the need to balance the proportion of legumes in feed intercropping and nitrogen fertilization levels to achieve optimal results. The paper notes the challenge of determining the optimal proportion of species components that maximize feed quality while minimizing environmental pressure.
