Agriculture faces significant challenges to satisfy the need for food production without significantly increasing the area under cultivation (Stevenson et al. 2013). Improved control practices including reduced or no-tillage management, crop residue addition, crop rotation, and the balanced nutrient application will increase soil organic carbon and improves agricultural sustainability (Six et al. 2002)
The insufficient supply of food to the poor community of ever-increasing global population is a much-highlighted problem. This situation has elevated the pressure to provide more food, and agriculture has effectively met the challenge of feeding this ever-growing population. But regrettably, the agriculture system has not been planned with the goal to support human health, food/nutrition security. (Mayer et al., 2008).
These days, due to the cultivation of high yielding wheat genotypes and using new agricultural structures, modern plant breeding has been extraordinarily oriented towards high agronomic yield instead of the nutritional high quality of the crop. (Morris and Sands, 2006).
In keeping with a latest WHO record, Zn deficiency ranks 5th among the most critical health risk factors in developing countries and 11th global, and it’s far equally as critical as iron (Fe) and vitamin A deficiencies. Micronutrient de?ciencies a?ict more than two billion people, or one in 3 people, globally (FAO et al., 2015).
In adult males, zinc de?ciency might also cause prostatic hyperplasia, affecting the reproductive characteristic and fertility. however, zinc supplementation is a powerful therapeutic tool in dealing with a long list of illnesses (Bhowmik et al. 2010).
Wheat (Triticum aestivum L.) is the most widely planted crop in the world, occupying approximately 22% of worldwide’s total cultivated area (Leff et al., 2004; Shewry, 2009). Wheat accounts for 9.1% of the value added in agriculture and 1.7% of GDP of Pakistan. The wheat crop was cultivated on an area of 8,734 thousand hectares with the production of 25.492 million tonnes (GOP, 2017-18)
Wheat (Triticum aestivum L.) is the most important dietary source of food supplying up to 50% of the everyday calorie intake of populations in developing countries (Cakmak,2008). In recent times, due to the cultivation of high yielding wheat genotypes and the use of new agricultural systems, modern plant breeding has been extraordinarily oriented towards excessive agronomic yield instead of nutritional quality (Morris and Sands, 2006). Soil Zn deficiency in major wheat growing areas leads to inherently low grain Zn concentration and is considered as a major factor in low human Zn intake (Alloway, 2009).
The problem of low grain Zn concentrations is exacerbated via inadequate selection of wheat cultivars and by the fact that many soils on which wheat is grown are low in plant-available Zn. this could be due to low total soil Zn concentrations or to factors that limit the availability for plant uptake of soil Zn which is actually found in sufficient quantities (e.g. in calcareous soils). The most important soil factors leading to the low availability of Zn in soils are high pH, high contents of calcium carbonate, clay, iron, and aluminum oxides and low moisture content (Alloway, 2009; Cakmak, 2008).
