Abstract

In order to study the effects of organic amendment application on growth and biochemical characteristics of French marigold (Tagetes patula) in a soil contaminated with different levels of gas condensate, a factorial experiment has been conducted based on a completely randomized design with three replications. The experimental factors are gas condensate at five levels of 0, 7500, 15000, 30000, and 60000 μ L per kg of soil, and soil amendment includes vermicompost (5%), biochar (2%), Activated carbon (1%), vermicompost + Activated carbon + biochar, and non-amendment (control) treatments. Results from the analysis of variance show that the main and interactive effects of gas condensate and soil amendments are significant on fresh and dry weight of root and shoot, chlorophyll a and b, and proline content (P<0. 01). At the highest contaminant level, application of Activated carbon and vermicompost plus Activated carbon plus biochar causes an increase of 3. 82 and 4. 45-fold in shoot fresh weight, 3. 76 and 4. 4-fold in root fresh weight, and 2. 52 and 2. 56-fold in chlorophyll a, respectively. It also decreases 30. 66% and 39. 5% of proline content, compared to the control at this level of the contaminant. Results of this research indicate the effective and useful role of organic soil amendment, especially Activated carbon and vermicompost + Activated carbon + biochar in reducing the toxicity of gas condensate on French marigold.
