Nutritional Evaluation of Durum Wheat with Respect to Organic and Chemical Fertilizers

Organic food is considered as safe as and healthier than their conventionally grown counterpart, but superiority over nutrient content is still undecided between these. Wheat, one of the main staple foods and a significant source of nutrients, is essential for human health. It is an input-intensive crop and requires a sizeable amount of organic and chemical fertilizers. Determination of the effect of organic and chemical sources on the nutritional quality of durum wheat (cv. GW-1) was the main objective of this study. The comparison of nutritional quality of organically and chemically amended wheat was made on many biochemical parameters (moisture, carbohydrate, oil, protein, ash, fiber, water-soluble vitamins), anti-nutrients (heavy metals and phytic acid) and mineral composition (Fe, Mn, Zn and Cu). The results revealed that durum wheat supplemented with chemical fertilizer recorded significantly higher amount of anti-nutritional factors, but lower in protein, zinc and water-soluble vitamin content. The present investigation reflected that durum wheat grown under organic fertilizers were at par with chemically supplemented wheat for nutritional quality, but were safer due to the significantly lower content of anti-nutritional factors. Therefore, consumption of organically grown durum wheat is able to supply nutrients and simultaneously reduces the risk of exposure to many harmful chemicals.
