“…In nature, plants often secrete specific nonprotein AAs known as phytosiderophores from their roots into the soil to improve micronutrient availability (Dakora and Phillips, 2002;Kinnersley, 1993). For this reason, many micronutrient foliar sprays (for Fe, Zn Nicotianamine and other unspecified amino acids Yuan et al (2013) example, Koksal et al, 1999;Rodríguez-Lucena et al, 2010) and hydroponic solutions (for example, Ghasemi et al, 2012) contain AA mixtures.…”

“…Nicotianamine has also been shown to have positive effects on plant physiological processes, even when applied exogenously, and it can therefore be considered a biostimulant. Specifically, exogenous application of nicotianamine increased the translocation of Zn and Fe to the grains of rice plants, which has important implications for human nutrition (Yuan et al, 2013).…”

“…Protein hydrolysates are marketed as plant biostimulants that can be applied as a foliar spray, soil drench, or seed treatment (du Jardin, 2012; Maini, 2006). The scientific literature discusses both pure AA (Ghasemi et al, 2012;Rodríguez-Lucena et al, 2010;Yuan et al, 2013;Zhou et al, 2007) and protein hydrolysates (Ertani et al, 2009;García-Martínez et al, 2010;Maini, 2006;Schiavon et al, 2008). In this review we will refer to both protein hydrolysates and pure AA as "AA," and specify the name of the pure AA when it is relevant.…”

“…In wheat, foliar application of Zn fertilizer improved both productivity and grain Zn concentration up to three or four fold as a foliar spray (Cakmak 2008). In rice, foliar application of Zn significantly increased Zn accumulation in the grain (Yuan et al 2013). Thus, enrichment of seeds with Zn benefits both crop production and health of the consumers, especially those whose Zn intake comes primarily from cereal grains.…”

This study evaluated how zinc (Zn) concentration of rice (Oryza sativa L.) seed may be increased and subsequent seedling growth improved by foliar Zn application. Eight foliar Zn treatments of 0.5% zinc sulfate (ZnSO 4 Á 7H 2 O) were applied to the rice plant at different growth stages. The resulting seeds were germinated to evaluate effects of seed Zn on seedling growth. Foliar Zn increased paddy Zn concentration only when applied after flowering, with larger increases when applications were repeated. The largest increases of up to ten-fold were in the husk, and smaller increases in brown rice Zn. In the first few days of germination, seedlings from seeds with 42 to 67 mg Zn kg À1 had longer roots and coleoptiles than those from seeds with 18 mg Zn kg À1 , but this effect disappeared later. The benefit of high seed Zn in seedling growth is also indicated by a positive correlation between Zn concentration in germinating seeds and the combined roots and shoot dry weight (r ¼ 0.55, p < 0.05). Zinc in rice grains can be effectively raised by foliar Zn application after flowering, with a potential benefit of this to rice eaters indicated by up to 55% increases of brown rice Zn, and agronomically in more rapid early growth and establishment.

“…Similarly in a multi-location study in China, India, Lao PDR, Thailand and Turkey Zn concentration in unhusked rice grain was about 69 % higher with foliar application than with soil application; at some centres it was almost twice of that with soil application [28]. In a recent study addition of 0.5 % w/v ZnSHH to a Fe-amino acid fertilizer increased Zn concentration in rice grain by 42.4 % [29]. Although ZnHI and ZnMEI were not much influenced by sources and method of Zn application, both agronomic and apparent recovery efficiencies of ZnSHH or Zn-EDTA were much higher with foliar application and declined as the number of foliar applications was increased.…”

Zinc deficiency in human nutrition is widespread in developing Asian and African countries where cereal grains are the staple food. Agronomic biofortification of Zn is a new innovative approach to get rid of Zn malnutrition from the poorest of the poor rural masses, who will never have money to buy mineral supplements nor can afford to improve the components of their diet by incorporating animal products. Hence, a field experiment was conducted during 2010 and 2011 on a sandy clay-loam soil (typic Ustochrept) at New Delhi, India to study the effect of NPK fertilization and to compare zinc sulphate heptahydrate (ZnSHH) and Zn-EDTA for growth, yield attributes, grain and straw yield, Zn concentration and uptake and Zn use efficiency in Basmati rice cultivar 'Pusa Sugandh 5' when applied to soil ZnSHH and Zn-EDTA were equally effective. Three foliar applications of ZnSHH increased Zn concentration and uptake by rice as compared to its soil application. Three foliar applications of Zn-EDTA (at tillering, booting and grain filling stages) was the best treatment and recorded significantly better growth, higher values for yield attributes, higher grain and straw yield and higher concentration and uptake of Zn in grain and straw of Basmati rice than soil application of ZnSHH or Zn-EDTA and two or a single foliar application of ZnSHH or Zn-EDTA. Three foliar applications of 0.5 % solution of Zn-EDTA recorded significantly higher head rice recovery than soil application. The highest KLBC, KLAC and KLER were obtained with three foliar applications of 0.5 % solution of Zn-EDTA.Keywords Milling and cooking quality parameters Á Zn sulphate hepta hydrate Á Zn-EDTA Á Foliar application Á Zn biofortification of rice Á Zn use efficiency
