Average of all countries -Zn: 26 +Zn: 50 Average Grain Zn Concentrations (10 Countries with 32 locations) -Zn: 26 ppm +Zn: 50 ppm Grain Zn concentration in different countries with and without zinc fertilization

IZA Crop Zinc Trials India – 17 wheat and rice trials China – 24 trials in 6 provinces with rice, wheat & maize Thailand - 2 rice trials South Africa - 2 maize trials Brazil – 2 soybean trials Total of 47 crop trials globally

There was an increase in grain yield up to 20 % by Zn application in the experimental sites of the Nakorn Nayok and Chiang Mai Provinces

Zinc Applications improved rice grain yield up to 30 % in some locations of the Orissa State INDIA

Zinc Applications improved wheat grain yield, on average, 9 % in 6 locations of the Uttar Pradesh and Haryana States

Zinc Applications improved wheat grain yield , on average , 7 % in 3 locations of Punjab State

Zinc Applications improved rice grain yield, on average, 9 % in 4 locations of the Punjab State

No change in maize grain yield in South Africa by Zn applications; but grain Zn was increased up to 20 %

Zinc Applications improved rice grain yield 20 % in 2 locations of Sichaun, China
