Abstract: The study entitled, “Effect of EDTA on phyto extraction of Pb by sunflower (Helianthus annuus L.)†was undertaken by conducting a micro-plot experiment in the net house of Micronutrient Research Project (ICAR), Anand Agricultural University, Anand (Gujarat) during kharif season of the year 2015. The soil used for the experiment was alkaline in reaction with low in available P205 and medium in K20. The Pb status was 0.00025 mg kg-1 soil, which was spiked with 300 mg Pb kg-1 soil before 30 days of sowing for the purpose of artificial contamination for the study. Three levels of EDTA (3, 6 and 9 mmol kg-1 soil) and three periods of EDTA application (P1: 6th, 7th and 8th weeks after sowing, P2: 9th, 10th and 11th weeks after sowing and P3: 12th, 13th and 14th weeks after sowing) and one absolute control were kept for the study. The lead content of seed, shoot and root was significantly more under E9P1, combination than the rest of the combination except E6P2 for seed and shoot and E9P2 for root. The uptake of Pb by shoot and total uptake were significantly more under E9P1 as compared to the rest except E6P2, while uptake by seed was maximum under E6P2. Remediation of Pb polluted soil is possible by using EDTA.
