In poultry dung average pH, conductivity, organic carbon, nitrate, phosphate and arsenic content were found as 7.25± 0.59, 1.256± 0.08 mS, 218.4± 32.75mg/gm, 2.57± 0.17mg/gm, 21.44 ±4.47mg/gm, and 0.038±0.005mg/gm respectively. In sodium arsenite contaminated culture with arsenic concentration ranging from 0.5 to 10 ppm, maximum seed germination was found in 0.5 ppm As (98.88%) and minimum in 10 ppm (30 %). Germination index (GI), relative growth index (RGI) and quality index (QI) also showed a maximum of 96.61%, 95.54% and 0.234% respectively at 0.05 ppm As in arsenic contaminated culture. Poultry dung suspension (PDS) culture showed 100% seed germination in 1%, 3% and 5% poultry dung suspension (PDS) and in 7%,10%, 15%, 20%, 25% and 50% the germination was found as 98.88%, 96.66%, 86.66%, 73.33%, 71.11% and 53.33% respectively with a maximum of 99.12% GI, 98.21% RGI and 1.44% QI at 1% PDS respectively. Thus PDS culture was favourable for germination and seedling potential of gram Copyright@ International Science Community Association
