Toward a Green Revolution in soybean: The role of ultra-high-density planting

Soybean is a major crop that provides essential protein and oil for human consumption. Despite the increasing global demand, soybean yield has not experienced a "Green Revolution" comparable to that of rice, wheat, and maize. Here, we propose a pathway toward a soybean Green Revolution: Enhancing soybean yield through the cultivation of dwarf soybeans optimized for ultra-high-density planting with a dwarf and dense-planting-tolerant soybean variety Dongsheng 89 as a paradigmatic case. We also suggest an ideal plant architecture and specific sowing and fertilization techniques. Furthermore, we discuss the prospective application of the rin1 gene in driving a global soybean Green Revolution, highlighting its potential to sustainably boost yields and address future food security challenges.
