Corn is one of the most important cereal crops grown in Guizhou with a total yearly output and growing area second only to rice. Corn production has in creased significantly during the last 40 years, from 598 thousand tones to 3.42 million tones. While demand for food increases, the potential for meeting that demand decreases. The per capita availability of land and water are steadily going down, while biotic and abiotic stresses limiting crop production are increasing. Adverse ecological and socio-economic factors are hindering the further development of corn production. This paper describes the current situation, the importance of integrated practices in increasing yields, challenges and opportunities in improving sustainable development of corn production in Guizhou.
