Abstract

Marigold is one of the most popular annual ornamental plants. Six different varieties of African marigold (T. erecta) viz. Local Selection, Pusa Narangi Gainda, Pusa Basanti Gainda, African Tall Orange, Sunset Giant and Inca-Hybrid were grown in sodic soils having 9.9 (control), 20, 30 and 40 ESP levels to evaluate the effect of sodicity on chlorophyll content (mg/g) in leaves of these varieties. The experiment was laid in Factorial CRD design with a total of twenty four treatments and three replications. Experiment was conducted consecutively for two years i.e. during 2010-11 and 2011-12. Sodic soils were artificially prepared using different concentrations of sodium bicarbonate for each ESP levels. It was found that chlorophyll ‘a’ and chlorophyll ‘b’ contents along with total chlorophyll decreased with increase in sodicity levels. The decrease in chlorophyll ‘a’ content was 2%, 16% and 30% while, chlorophyll b showed 13%, 27% and 34% reduction at 20, 30 and 40 ESP levels of sodicity. Similarly, the total chlorophyll decreased progressively at each sodicity levels. The reduction in total chlorophyll was 8%, 23% and 30% at 20, 30 and 40 ESP levels, respectively. Inca-Hybrid maintained its chlorophyll content significantly higher (chl’a’ 2.46 and 2.42 mg/g, chl’b’ 0.87 and 0.85 mg/g and total chl 3.36, 3.34 mg/g) than other five varieties while Sunset Giant variety (chl ‘a’ 2.04 and 1.99 mg/g, chl’b’ 0.60 and 0.57 mg/g and total chl 2.65 and 2.60 mg/g) showed poorest performance among all the varieties.
