Abstract: The field experiment was carried out in Agroforestry Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar, Uttarakhand during the rabi season for two years 2014-15 and 2015-16 to study the comparative performance of wheat varieties under poplar based agroforestry system. Five wheat (Triticum aestivum L.) varieties (PBW-343, UP-2565, WH-711, DBW-17 and VL-907) were tested in randomized block design with three replications (under poplar plantation and in open field) during both the years. Among different wheat varieties under poplar based agroforestry system, spike length was found significantly higher in UP-2565, number of fertile spikelets, grains per spike, grain weight per spike and test weight in VL-907 under poplar based agroforestry system while number of infertile spikelets was observed higher in PBW-343 during both the years. Wheat variety VL-907 showed the maximum biological yield among wheat varieties under poplar based agroforestry system during Y₁ and Y_2.while, biological yield was lower among different wheat varieties under poplar based agroforestry system than open farming system. Maximum grain yield under poplar based agroforestry system was recorded in wheat variety VL-907 during Y₁ and Y₂, respectively, However open farming system had more grain yield than poplar based agroforestry system. Straw yield was also more in VL-907 in 2014-15 and in 2015-16 more in PBW-343 under poplar based agroforestry system. Among wheat varieties, VL-907 had maximum harvest index in poplar based agroforestry system. Harvest index was higher in poplar based agroforestry system than open farming system. Among the different wheat varieties grown with poplar, wheat variety VL-907 gave the better performance under agroforestry system as well as open farming system during both the years of experiments.
