“…Biofortification can be applied to increase the iron concentrations in polished seeds and to achieve the target iron demand for human nutrition. Sperotto et al (2012) suggested conventional breeding or directed genetic modification as two possible ways to develop iron-rich rice plants. Iron concentrations in rice have a narrow variation, ranging from 6 to 22 g L -1 as compared to 10 to 160 g L -1 in maize and 15 to 360 g L -1 in wheat (Gómez-Galera et al, 2010); however, most maize genotypes do not reach the highest values (Ortiz-Monasterio et al, 2007).…”

“…Slaton et al (2001) reported that either Zn seed treatment or soil Zn fertilizer increase Zn content in rice plant tissue compared to control. It is a different case with Iron, which crop Fe fertilization is not very effective due to Fe soil insolubility (Sperotto et al 2012). On the other hand, organic farming system decreases Fe and Zn content (Sakagami et al 2016).…”

Abstract. Susanto U, Barokah U, Hidayatullah A, Satoto, Swamy M. 2017. Yield and Zn content of biofortified rice genotypes in an Indonesian rice . Approximately one-third of the world's population suffer from Zn deficiency causing significant socio-economic losses as a result of stunting and compromised immune system function. One strategy to overcome the problem is by developing rice cultivars with high grain Zn content (Zn Rice) to improve dietary intake.This study reports the yield and Zn content of 22 rice genotypes developed at the International Rice Research Institute (IRRI) and the Indonesian Centre for Rice Research (ICRR).The experiment was conducted in the Cirebon district of West Java province during the 2013 wet season (2013WS). Yield and grain Zn content (using an XRF machine) were measured. Five lines demonstrated higher yield (ranging from 7.0 to 8.9 t/ha) than the check variety Ciherang (5.2 t/ha), but had similar grain Zn content to the check variety Ciherang (23.4 ppm), ranging from 19.0 to 24.8 ppm. On the other hand, seven lines had higher grain Zn content (ranging from 30.0 to 34.2 ppm) compared to Ciherang, and five of these lines had comparable yield to Ciherang. The selected lines had acceptable agronomic traits, and are suitable for further testing and utilization, in addition to providing a foundation for future improvement in the dual goals of increasing the yield and nutritional value of rice.

“…Therefore, it is important to ameliorate the mineral concentrations in milled rice through breeding programs and agronomic approaches. Some screening studies have identified Fe-and Zndense genotypes with the aim of enhancing the mineral nutrition concentrations in milled rice (Sperotto et al, 2012;Wei et al, 2012a). Previous studies have also investigated the effects of fertilizer on the mineral element concentrations in milled rice, including the effects of fertilizer type, application pattern and application amount (Zhang et al, 2007;Wei et al, 2012a;He et al, 2013).…”

To date, information regarding the effects of Si on rice (Oryza sativa L.) nutritional quality is rarely reported. The current study was conducted to evaluate how Si fertilizer impacts the mineral element, protein and amino acid concentrations in brown and milled rice. The experiment was a randomized complete split-plot design, with Si treatments as main plot and two cultivars as subplot. Compared with the control, application of Si fertilizer significantly enhanced the Zn, Ca and Mg concentrations in brown and milled rice but had nonsignificant effects on the Fe, Mn and Cu concentrations. Moreover, application of Si fertilizer resulted in significant increases in the concentrations of protein and most of the amino acids in brown and milled rice. However, the Gly, His, Val, Met and Lys concentrations were unaffected by the application of Si. The responses of the Cys and Phe concentrations to Si fertilizer application were cultivar-dependent. Applying Si significantly increased Zn, Ca, Mg and protein concentrations by 21.77%, 25.77%, 7.25% and 6.19% in milled rice and by 25.18%, 39.81%, 9.24% and 5.52% in brown rice. These results indicate that Si fertilizer could improve rice nutritional quality by increasing concentrations of mineral elements, protein and some amino acids in brown and milled rice.
