Zinc (Zn) ferti-fortification using different sources and methods in Zn deficient soils is being
advocated to increase Zn concentration in rice kernel as an alternative to pursuing greater
Zn-use efficiency (ZnUE). A two-year field study was conducted to assess the effect of Zn
application on Zn content and uptake at several growth stages and in several parts of the
rice kernel: hull, bran, and the white rice kernel. Variety ‘PB 1509’ with 1.25 kg Zn ha−1 as
Zn-EDTA + 0.5% foliar spray (FS) at maximum tillering (MT) and panicle initiation (PI) stages
registered the highest Zn content in hull, bran, and white rice kernel. Among parts of the
rice kernel, Zn concentration decreased in the order hull > bran > white rice kernel,
indicating that brown rice kernels are much denser in Zn content than polished rice.
Considering the higher Zn accumulation in the bran, brown rice consumption, especially in
Asia and Africa, could be recommended to overcome Zn malnutrition. The variety ‘PB 1401’
showed the highest Zn uptake in rice straw, while ‘PB 1509’ showed the highest Zn uptake
in hull and white rice kernel. Application of 1.25 kg Zn ha−1 (Zn-EDTA) + 0.5% FS at MT and
PI and 2.5 kg Zn ha−1 ZnSO4·7H2O (ZnSHH) + 0.5% FS at MT and PI resulted in higher Zn
uptake than other treatments. On average, about one third of total Zn uptake remained in
the white rice kernel, with the remaining two thirds accumulating in both hull and bran of
brown rice. Zn-EDTA along with 0.5% FS, despite the application of a lower quantity of Zn
leading to the highest Zn mobilization efficiency index (ZnMEI) and Zn-induced nitrogen
recovery efficiency (ZniNRE), produced the highest kernel yield. However, of the two Zn
sources, Zn-EDTA contributed more to the increase in ZnUE than did ZnSHH.
