Spring and summer drought results in poor seedling establishment and development, leading to 10-30% yield loss. Autumn drought prolongs the anthesis-to-silking interval, resulting in poor seed set, and can lead to 10-40% yield reductions, or in some cases complete crop loss. Four strategies are being pursued in South China to improve and stabilize maize production in drought prone areas. These are the use of improved maize varieties, agronomic practices, water management, and soil management. The main technical approaches include breeding maize hybrids that are tolerant to drought and responsive to water and fertilizer, seedling transplanting and plastic-film seed-bed mulching, water harvesting, and better crop rotation, irrigation and soil management.Collection: CIMMYT Publications Collection
