| dc.description.abstract | The present investigation was carried out at Agroforestry Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India, during March to October, 2017. The experiment was laid out in Factorial Randomized Block Design with three replications (3 open field + 3 under poplar canopy) and ten treatments. Study was conducted on Populus deltoides and ten germplasm of Colocasia esculenta namely PA-12, PA-16, PA-18, PA-29, PA-33, PA-49, PA-56, PA-60, PA-63 and PA-73. The quantitative characters of taro for days needed to 50 % sprouting, plant height, collar diameter of plant, number of leaves per plant, leaf length, leaf breadth, leaf area index, weight of corms and cormels per plant, number of corms and cormels per plant, width of corms and cormels, length of corms and cormels and tuber yield were recorded, which were higher in the open system as compared to poplar based agroforestry system. Among the germplasm, the maximum (145.74 q/ha) yield was recorded in germplasm PA-16 under agroforestry system while under open system, maximum yield was observed in germplasm PA-12 (364.10 q/ha). In poplar tree height, tree diameter, crown spread and tree volume was measured, which were increased and found that poplar gave 0.029 m3 per hectare. The physico-chemical property of soil for pH, electrical conductivity, organic carbon, available soil nitrogen, available soil phosphorus and available soil potassium were analysis, which were better under poplar based agroforestry system as compared to open farming system. | en_US |
