Nutrient management and high-quality-efficiency BF technology for super-high-yield wheat in Anhui province

English

IPNI-2009-CHN-AH18

Wheat is the primary grain crop in Anhui province with annual sowing area 2 million ha. Anhui is one of the five largest production provinces of winter wheat in China with 9% planting area and 7% of yield in China’s wheat production. The average wheat yield in Anhui in recent years was 3,195 kg/ha, it was about 80% of the average yield of the country. The main reason of low winter wheat yield in Anhui is unreasonable fertilization, especially for intensive high yield production. Read more

Interpretive Summary

Balanced Fertilization Strategy for High Wheat Yields in Anhui Province, 2011 Wheat is the main food crop grown in Anhui province with a total sowing area of 2 million ha annually. Anhui’s wheat average yield (3,195 kg/ha) was 18. 7% lower than the average yield of the country (3,932 kg/ha). One of the reasons for lower yield is unbalanced fertilization.

Nutrient Management and Balanced Fertilization Technology for Super High Yielding Wheat Cultivation in Anhui, 2010 Wheat is one of the important grain crops in Anhui, with a total area of over 2 million ha. Wheat yield in Anhui is lower than the national average because of both poor nutrient management and an unfavorable climate.

Nutrient Management and Balanced Fertilization Technology for Super-High-Yielding Wheat in Anhui, 2009 Anhui is one of the five largest winter wheat producing provinces in China. However, the average winter wheat yield is 3,195 kg/ha, which is 80% of the national average. Low yields are blamed on poor fertilization practices and this project is re-evaluating NPK fertilization throughout the province.
