Rice is a staple food for at least 50% of the world’s population. Therefore, it is one of the most important crop plants on Earth (Lucca et al., 2002). However, milled rice is a poor source of essential micronutrients such as Fe and Zn (Bouis and Welch, 2010), whose deficiencies affect over three billion people worldwide, mostly in developing countries (Welch and Graham, 2004). Fe and Zn malnut...

this paper concerns the removal of zn 2+ and cr 6+ ions from waste water using a naturally occurring zeolite from semnan region in iran. a continuous fixed-column study was carried out by using zeolite as a low-cost adsorbent for the removal of zn 2+ and cr 6+ ions from aqueous solution under the effect of various process parameters such as, grain size and time. the efficiency of removal is hig...

Micronutrient deficiencies in the diet of many people are common and wheat is a staple food crop, providing a carbohydrate and micronutrient source to a large percentage of the world’s population. We conducted a field study to compare five Canadian red spring wheat cultivars (released over the last century) grown under organic and conventional management systems for yield, grain micronutrient c...

Tensile–creep experiments were conducted in the temperature range 100–200 C and stress range 20–83 MPa for a series of magnesium–zinc–yttrium (Mg-Zn-Y) and mangnesium-zinc–zirconium (Mg-ZnZr) alloys ranging from 0 to 5.4 wt% Zn, 0 to 3 wt% Y, and 0 to 0.6 wt.% Zr. The greatest tensile– creep resistance was exhibited by an Mg–4.1Zn–0.2Y alloy. The room-temperature yield strength increased with i...

in order to investigate the impact of foliar zn application in reducing the negative effects of water stress on bean growth and yield, a field experiment was carried out in the research field of ilam university in 2011. the experiment was arranged in split factorial based on a randomized complete block design with three replications. the experimental factors were water stress including water wi...

BACKGROUND Wheat is the staple food for most of the world's population; however, it is a poor source of zinc. Foliar fertilization of zinc via zinc loaded chitosan nanocarriers (Zn-CNP) post-anthesis has proved to be a promising approach for grain zinc enhancement in durum wheat as evidenced in our earlier study. However, the molecular mechanism of uptake of zinc via Zn-CNP remains unclear. M...

Introduction: The Zakłodzie meteorite, a moderately weathered find discovered near the village Zakłodzie, Poland, is an ungrouped enstatite-rich achondrite ascribed to an impact melt [1] or internal melting within the parent body [2]. During our nanomineralogy investigation of the Zakłodzie meteorite, a new Fe-dominant monosulfide mineral, (Fe,Zn,Mn)S with the P63mc wurtzite-type structure was ...

The relationships between grain yields and whole-plant accumulation of micronutrients such as zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu) in maize (Zea mays L.) were investigated by studying their reciprocal internal efficiencies (RIEs, g of micronutrient requirement in plant dry matter per Mg of grain). Field experiments were conducted from 2008 to 2011 in North China to evaluate RIEs...

A fundamental study on the adsorption of metal elements on Shirasu, a pyroclastic flow deposit distributed in southern Kyushu, Japan, has been conducted. The adsorption experiment was carried out by a batch method, and by using Zn(II) and Cu(II) under several conditions; the effects of the initial concentration of metal ions, grain size, and pH were investigated. At smaller grain sizes, the amo...

to study effect of fe and zn spraying on some characteristics of mungbean, an experiment was designed as factorial based on randomized complete block with three replications in urmia university, 2012. treatments were nutrition systems (organic, chemical, integrated and no nutrition) and micronutrients (fe, zinc, no foliar application and water spraying). the plant height, pod length, number of ...
