Abstract

For two years, field experiments were carried out at Agro-Forestry Research Center of G.B.P.U.A. & T., Pantnagar, Uttarakhand (29°N Latitude, 79°30’ E longitude and at an altitude of 243.84 msl) during 2013-14 and 2014-15, to study the growth, biomass and carbon sequestration potentials of poplar clones in association with different wheat varieties in a sandy loam soil. The soil of the experimental site contained 1.175% of organic carbon, 259, 20 and 195 kg/ha available nitrogen, phosphorus and potassium, respectively. The soil was almost neutral in reaction (pH 8.2). The study was laid in split plot with poplar tree clones viz., S7C8, G-48, W-39 and Kranti in main plots and wheat varieties viz., DBW-17, PBW-502, UP-2748 and HD-2967 in sub-plots. Poplar trees were planted at spacing of 7.0m x 3.0m.
Poplar clones S7C8 in 2013-14 and Kranti in 2014-15 recorded higher values of diameter at breast height (DBH) and tree height than clones W-39 and G-48. Wheat variety DBW-17 exhibited higher values of poplar growth than varieties PBW-502 and UP-2748. In 2013-14 clone S7C8 recorded the highest values of different components of trees biomass. In 2014-15, clone Kranti produced significantly higher stem, roots and total biomass than clones G-48 and W-39. The total carbon sequestered by the agroforestry system during both the years, was the highest with the clone Kranti (57.14 t/ha in 2013-14 and 65.69 t/ha in 2014-15). In 2014-15, the total carbon sequestered by clone Kranti was significantly higher than other clones. The total carbon sequestered by the agroforestry system was the lowest with the clone G-48.
Except carbon stock in wheat plant biomass, wheat varieties did not affect the poplar growth, biomass and carbon stock of the agroforestry system significantly. Wheat variety DBW-17 in 2013-14 and HD-2967 in 2014-15 recorded the highest amount of carbon in plant biomass.
