Abstract

Soybean, an important raw material in vegetable oil and protein-rich human food and animal feed, plays an important role in world food security. With the economic growth and changing diet, the global future food demand will continue to increase, especially the soybean. In the case of China, Chinese soybean consumption has exceeded 100 million tons in 2017, while the self-sufficiency rate is only approximately 15%. Therefore, China’s soybean supply gap is huge. Many researchers have investigated that planting soybeans densely can remarkably increase in total aboveground biomass and seed yield. In addition, the plots with typical or high yield records often have higher planting density. In Arkansas, United States, a record soybean yield of 7,501.0 kg ha-1 was recorded with a planting density of 371,000 plants ha-1 in 2014. In Xinjiang Province, China, the highest soybean was 6,088.4 kg ha-1 with a planting density of 299,000 plants ha-1 in 2010. Soybean plants can intercept and use solar radiation more efficiently under dense planting, which is an important cultivation measure for high soybean yield.
