Abstract

The present investigation titled, “Effect of Silver Oak (Grevillea robusta) and poplar (Populus deltoides) based Agroforestry systems on growth and yield attributes of different varieties of Wheat (Triticum aestivum) in Dehradun region” was carried out to examine the effect of different agroforestry systems on growth and yield attributes of different varieties of wheat crop. Under open condition, VL Gehun 804 variety was found to have average maximum plant height as on 30, 90 and 120 DAS; number of tillers per running row meter as on 60 and 90 DAS; Tiller Production Rate 60-90 DAS; dry weight as on 30, 60, 90 and 120 DAS; number of effective tillers; flag leaf length; spike length; number of grains per spike; grain yield; and Harvest Index. VL Gehun 738 variety was found to have average maximum plant height as on 60 DAS. VL Gehun 907 variety was found to have average maximum number of tillers per running row meter as on 30 DAS and average maximum Tiller Production Rate 0-30 DAS. VL Gehun 401 variety was found to have average maximum Tiller Production Rate 30-60 DAS. VL Gehun 832 variety was found to have average maximum test weight and straw yield. Under Poplar based agroforestry system, VL Gehun 804 variety was found to have average maximum plant height as on 30, 60, 90 and 120 DAS; number of tillers per running row meter as on 30, 60 and 90 DAS; Tiller Production Rate 0-30 DAS; dry weight as on 30, 60 and 120 DAS; number of effective tillers; and flag leaf length. VL Gehun 616 variety was found to have average maximum Tiller Production Rate 30-60 DAS. Both VL Gehun 802 and VL Gehun 829 varieties were found to have average maximum Tiller Production Rate 60-90 DAS. VL Gehun 719 variety was found to have average maximum dry weight as on 90 DAS. VL Gehun 892 variety was found to have average maximum number of grains per spike. VL Gehun 832 variety was found to have average maximum test weight. VL Gehun 832 variety was found to have average maximum spike length and straw yield. VL Gehun 829 variety was found to have average maximum grain yield and Harvest Index. Under Oak based agroforestry system, VL Gehun 804 variety was found to have average maximum plant height as on 30, 60, 90 and 120 DAS; number of tillers per running row meter as on 30, 60 and 90 DAS; Tiller Production Rate 0-30 DAS and 60-90 DAS; dry weight as on 60 and 120 DAS; number of effective tillers; flag leaf length; spike length; and Harvest Index. VL Gehun 719 variety was found to have average maximum Tiller Production Rate 30-60 DAS and dry weight as on 90 DAS. VL Gehun 892 variety was found to have average maximum number of grains per spike. VL Gehun 832 variety was found to have average maximum test weight and straw yield. VL Gehun 829 variety was found to have average maximum dry weight as on 30 DAS and grain yield.
