Rerkasem B. Prom-u-thai C. © 2016, Springer International Publishing Switzerland. Background and aims: Rice crop management for Zn biofortification should also benefit yield. This study established how grain Zn concentration and yield of rice varieties with a range of grain Zn concentration vary under different N-fertilizer applications. Methods: Rice varieties, the low-yield/high grain Zn varieties KPK and NR, the high-yield/medium grain Zn variety KDML105 and the high-yield/low grain Zn varieties CNT1 and RD21, were grown under field conditions with fertilizer rates of 60 and 120 kg N ha −1 . Results: Increasing N rate increased grain Zn concentration and yield in the high-yield/low grain Zn varieties, but depressed grain Zn concentration and increased grain yield in the low-yield/high grain Zn varieties. On the other hand, it increased grain N in all five varieties. Grain Zn concentration was associated positively with yield and grain N concentration in low grain Zn concentration varieties, but negatively in high-grain Zn varieties. Conclusions: Nitrogen fertilizer increased grain Zn concentration and yield simultaneously in low-grain Zn varieties, but depressed grain Zn concentration, while boosting yield, in high-grain Zn varieties. 2017-09-28T04:11:19Z 2017-09-28T04:11:19Z 1-2 Journal 0032079X 2-s2.0-84988345239 10.1007/s11104-016-3056-1 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84988345239&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/40759
