Abstract:
An experiment was conducted on basmati rice (var. Pusa Basmati 1121) in 2016 to study the distribution of micronutrient in different parts of rice on sludge treated and metal polluted soils. The different doses of sludge were used as treatments 0, 10, 20, 30, 40 and 50 g/kg in IARI soil whereas, Debari soil is used as such treatment. The results indicated that total (aqua regia extractable) Zn, Cu, Fe and Mn varied from 94.4-1032 mg/kg, 17.1-24.2 mg/kg, 1.12-1.93% and 590-652 mg/kg, respectively throughout the treatments with corresponding values for EDTA extractable micronutrients were 3.94-329, 3.03-6.18, 81.5-167 and 47.3-95.6 mg/kg, respectively. DTPA extractable micronutrients in post- harvest soil were significantly higher in sludge application @ ≥ 30 g/kg treatments. Distribution of Zn and Cu content in rice crop found in the following order straw > grain > husk whereas, Fe and Mn found with the following sequence straw > husk > grain. Finally, it can be concluded that zinc and iron content in brown rice was increased with increase rates of sludge application, which may help in alleviating the deficiency of these two micronutrients in human.
