Economic analysis of different organic manures in sweet potato production under poplar-based agroforestry system

Field study was conducted at the forest nursery and research center, School of Forestry and Environment, Sam Higginbottom Institute of Agriculture Technology and Sciences, Deemed University, Allahabad, UP on economic analysis of the use of different organic manures on sweet potato production under poplar based agroforestry system. The experiment was laid out in shade (under trees) condition with 7 treatments replicated thrice in randomized block design (RBD). The vine cuttings of sweet potato (20-25 cm) veriety Pusa Red were planted at 45 x 60 cm spacing. N, P2O5 and K2O were applied in the form of farm yard manure (FYM), vermicompost and neem cake. The highest cost of cultivation was recorded in neem cake (Rs 72071.36) and gross return and net return (Rs 99204.00 and Rs 57299.00 respectively) in vermicompost. However benefit/cost ratio was maximum in FYM (1:1.02) under poplar trees.
