Potato response to potassium fertilizer combined with different P sources in Inner Mongolia, China

This project initiated in 2016 and mainly evaluate the effect of MOP and/or SOP combined with DAP and new compound fertilizer containing N, P S and Zn on potato yield and farmer's income.

IPNI-2016-CHN-NM02

The objectives of this study were to compare the effects of potassium chloride (KCl) and potassium sulfate (K2SO4), along with their combinations with diammonium phosphate (DAP) and MESZ (12-40-0-10S-1Zn), a new P fertilizer containing sulfur and zinc), on potato tuber yield and economic returns.

Potassium Fertilizer Research is Reviving Potato Production in China China is the largest global potato producer and Inner Mongolia (IMAR) is one of the country’s major potato-growing regions. Without proper K fertilization, a reduction in potato yield, quality, and farmer profitability has been observed. The IPNI China Program established a research project that helped the region’s potato farmers increase their productivity and profitability by identifying the most beneficial rates, sources, and times of K application.
