Chinese agricultural scientists are reporting significant advances in crop yields, achieving production levels once deemed unattainable. These developments mark a sharp contrast to the exaggerated and ultimately disastrous claims made during the Great Leap Forward campaign in the late 1950s, which contributed to widespread famine.

In June 1958, official reports from central Henan province claimed crop yields exceeding 3,000 jin per mu (approximately 22 tonnes per hectare). These figures, supported by theoretical calculations from scientist Qian Xuesen on maximum solar energy use in photosynthesis, were subsequently inflated to as much as 10,000 jin per mu. The resulting pressure to meet unrealistic targets disrupted agricultural practices and precipitated one of the deadliest famines in modern history.

Nearly seven decades later, experimental farms in China are again achieving yields of around 3,000 jin per mu, but these results are based on consistent two-crop annual rotations rather than isolated, unverified harvests. Dezhou city in Shandong province exemplifies this progression through its "tonne-and-a-half grain" program, which has contributed to sustained high productivity.

Yu Zhenwen, an academician at the Chinese Academy of Engineering and professor at Shandong Agricultural University, credited ongoing scientific and technological efforts for these outcomes. Unlike the Great Leap Forward era, current achievements have attracted limited public attention, in part due to the widespread availability and affordability of food across China today.

Official data highlight that the 2025 summer grain harvest reached approximately 150 million tonnes (301 billion jin), with average national grain yields rising to about 750 jin per mu. Despite having substantially less arable land per capita compared to countries like the United States, China has become one of the world's most efficient grain producers by land productivity measures.

In addition to cereals, China’s output includes around 820 million tonnes of vegetables and nearly 360 million tonnes of fruit annually—figures significantly higher than those of the United States, which produces about 35 million tonnes of vegetables and 26 million tonnes of fruit and nuts per year.

Cereal production in 2025 totaled 660 million tonnes, including 301 million tonnes of corn, 209 million tonnes of rice, and 140 million tonnes of wheat. Rice yields averaged approximately 960 jin per mu, comparable to leading producers such as Japan and South Korea. Wheat yields were reported to be roughly twice the global average. Overall grain production reached a record 714 million tonnes, driven largely by increases in corn output.

Much of the recent yield growth stems from research conducted on experimental farms designed to push the biological limits of crop production. For instance, super rice demonstration plots have consistently exceeded 2,000 jin per mu, about double the standard yields in many conventional rice-growing areas. Advances include gene-edited, densely planted maize and new hybrid rice varieties.

In a notable development announced in July, Chinese scientists achieved over 99 percent cloning efficiency in hybrid rice breeding, fulfilling part of the legacy of Yuan Longping, regarded as the father of hybrid rice. This breakthrough is expected to further enhance food security through improved crop performance.

Researchers emphasize the critical role of science and technology in supporting farmers and advancing agriculture, signaling continued momentum in China’s efforts to increase food production sustainably.
