Interpretive Summary

2013

During 2012 and 2013, 60 cotton fields were randomly selected to investigate the relationship between soil K supply and cotton yield/fibre quality in Hebei, Henan, Shandong, and Xinjiang Provinces. The effects of application rate and time of K fertilization on cotton yield and fiber quality were also studied in each province.

2012

Thirty cotton fields were randomly selected in Hebei, Henan, Shandong, and Xinjiang province to investigate the relationship between soil K supply and cotton yield/fiber quality. The effects of rate and time of K application on cotton yield and fiber quality were also studied in each province. The average soil exchangeable K values of selected cotton fields were higher in Xinjiang (244 mg/kg) and Shandong (267 mg/kg) than in Hebei (107 mg/kg) and Henan (126 mg/kg).
