Potassium, Sulphur and Zinc Application Improved Yield and Economics of Rice-Wheat Systems

On-farm experiments conducted at 60 locations in northern India demonstrated that yields and profits for rice and wheat increased significantly with a combined application of K, S and Zn along with farmer fertilisation practice that primarily focuses on N and P application. Application of Zn improved grain Zn contents in rice and wheat, which is critical for nutritional security in the region. Soil exchangeable and non-exchangeable K decreased without K application and increased with K application within just one rice-wheat cropping cycle.
