The present investigation was carried out at Agroforestry Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India, to study the chemical property of soil before and after the growth of taro as sole crop and under poplar based agroforestry system. After planting of taro, soil pH was observed maximum for germplasm PA-73 (7.23) and PA-16 (7.15), EC was observed maximum for germplasm PA-56 (0.40 dSm-1) and PA-60 (0.36 dSm-1) and soil organic carbon (OC) was observed maximum for germplasm PA-49 (1.17%) and PA-73 (1.06%) under poplar based agroforestry system and open system respectively, whereas after harvesting of taro, the maximum soil pH was observed with germplasm PA-16 for both the condition, which was 7.20 and 7.14, maximum soil EC was observed with germplasm PA-56 (0.39 dSm-1) and germplasm PA-60 (0.35 dSm-1) and maximum soil OC was observed under poplar based agroforestry system as compared to open system respectively. Results of the present study revealed that the chemical property of soil varied significantly in different taro germplasm under poplar based agroforestry system as compared to open farming system.References
