Nutrient Management on Potato

IPNI-2008-CHN-CQ11

Acid soils account for one-third of the total land area in Chongqing, southwest China. Soil acidity usually reduces the availability of plant nutrients and hinders crop growth. The objective of this experiment was to study the effects of different basic materials, P sources, and N and K rates on the availability of P and potato yield in an acid soil (pH 4. 5) in Chongqing.

Potato is a staple food for mountain dwellers particularly in Chongqing, accounting for one-fourth of total foodstuff consumed annually. In those remote regions, potato yield and quality are usually low mainly due to shortage of good variety, nutrient management, and other related agronomic practices. Thus, how to improve potato yield and quality through balanced fertilization is of great importance for both better income and human nutrition.
