Effect of Carpet Effluent and its Dilution on Seed Germination Potential and Seedling Growth of Hordeum vulgare var. RD 2508

The study Effect of carpet effluent and its dilution on seed germination potential and seedling growth of Hordeum vulgare var. RD 2508 was conducted at Tonk which is located in north-eastern part of the Rajasthan state between 75°07' to 76°19' east longitude and 25°41' to 26°34' north latitude. Aim of the study was to assess the delirious effects of original carpet effluent (100 %) and its dilutions viz. 5%,10%,25%, 50% and 75% on the relative germination potential and seedling growth parameters (7 days) like ischolar_main length, shoot length and total dry weight of Hordeum vulgare var. RD 2508 in comparison to the control. It was found that after 48 hours of sowing, percent germination of seedling showed a decreasing trend with increasing concentration of the effluent (from 5% - 100%).At 100% concentration, germination was only 11.66 % while it was 55.0 % and 31.66% respectively on 50% and 75% concentrations.

Growth parameters for seedling were also recorded after 7 days. Effect of the effluent content was more on shoot growth as compared to ischolar_main, at all the concentrations. Reduction in shoot and ischolar_main length were recorded up to 26.66% and 24.59% respectively at 25% effluent concentration in comparison to control. At higher effluent concentration (75%), the reduction in shoot length and ischolar_main length was 63.25% and 54.75% respectively. At the original concentration of effluent (i.e. 100%) the ischolar_main length and shoot length were 2.04 cm. and 1.04 cm. and the reduction percentage was 83.41% and 82.95% respectively. Plant dry weight also declined along with the increasing concentration of effluent. It was reduced upto 10.65% at 5% concentration, 17.21% at 10%, 26.22% at 25%, 39.34% at 50%, 58.19% at 75% and 84.42% at 100% effluent concentrations.
