THE INFLUENCE OF ORGANIC FERTILIZERS IN THE FORM OF INDUSTRIAL AND AGRICULTURAL WASTES ON Fe-TRANSLOCATION AND ACCUMULATION IN GRAINS OF WHEAT: ASSESSMENT OF PUBLIC HEALTH RISK.

Micronutrients perform a significant role in growth and development of human population, but food crops grown on metal deficient soil showed limited accumulation in their grains, leads toward human malnutrition. Present experiment evaluated the Fe effect in soil and different wheat varieties grown under organic fertilizers treatments. For this purpose, experiment was conducted in Municipal solid waste (MSW-100 & MSW-200g), Poultry waste (PW-100 & PW-200), Press Mud (PM-100 & PM-200), Farm yard manure (FM-100 & FM-200) and control (CT) treatment under both pot and field trials. Study results presented that organic fertilizer treatment significantly increases the Fe content in wheat varieties with respect to control treatment. Maximum Fe level (4.33-8.78mg/kg) was found in MSW-200 treated soil. Root (12.86-29.97mg/kg) and shoot (29.11 to 12.41mg/kg) samples showed maximum Fe mean value in 11CO23 variety grown in FM-200 treatment. Grains (12.46-29.63mg/kg) showed highest Fe accumulation in the JOHAR-16 grown in PM-200 treatment. Fe content was ranges as 0.076-0.154mg/kg in pollution load index, 2.878-4.609mg/kg in bio-concentration factor, 0.00542-0.01287mg/kg in Daily intake index and 0.7737-1.8386mg/kg/day in health risk index. In term of varieties and treatments, maximum Fe content was exhibited in JOHAR-16 during PM-200 treatment while its minimal concentration was recorded in IHSAN-16 during CT treatment. Organic fertilizer treatments basically enhance the Fe content in wheat grains; which proves to be fruitful in decreasing micronutrient malnutrition from human diet in future. [ABSTRACT FROM AUTHOR]
