Field experiments was conducted during the kharif seasons of 2012-14 at the forest nursery and research center, College of Forestry, Allahabad Agriculture Institute, Deemed University, Allahabad, on growth and productivity of Ipomoea batatas under poplar based Agroforestry system. The experiment was laid out in shade (under trees) condition with 7 treatment replicated thrice in Randomized Block design. A sweet potato variety known as Pusa Red was used for the study. The vine cutting of 15 cm length with 4-6 nodes of Pusa Red variety of sweet potato were planted in spacing 45cm × 60cm. Nitrogen, Potash, and Phosphorus was applied in form of organic manure Farm yard Manure, Vermicompost, and Neemcake. T3 (vermicompost) recorded highest survival percent , length of vine, number of branches/vine, shoot fresh weight, shoot dry weight, tuber yield/plot, number of tuber per plot under poplar trees. The maximum Gross return was noticed in T3 with Rs. 99204.00. The maximum Benefit cost ratio was noticed in T3 with 1:1.37
