摘要

Potato production in Inner Mongolia is limited by unbalanced nutrition and inadequate water supplies. Field trials find balanced fertilization can significantly increase tuber yield for both rainfed and irrigated potato. Crop uptake of N, P and K increased rapidly at 25 to 57 days after emergence (DAE) under both rainfed and irrigated conditions. The economic benefit from fertilizer application was higher in irrigated versus rainfed potato.
