Abstract
An experimental trial to know the effect of inter-cultivation of Populus ciliata Wall. ex Royle at different spacing, as a shade providing nurse crop on the survival and growth performance of Abies pindrow Royle and Picea smithiana (Wall.) Boiss. - high level conifers of Westren Himalayas was conducted in Solang valley of Himachal Pradesh. The results of the experimental trial revealed significant effect of inter-cultivation of Populus ciliata on the survival and growth performance of Abies pindrow and Picea smithiana. The maximum survival of both species was recorded under the shade of nurse crop at a spacing of 4 x 3 m. However, maximum average height and collar diameter increment of both species was recorded under the shade of nurse crop at a spacing of 6 x 3 m followed by plants under the shade of nurse crop at a spacing of 4 x 3 m. So it can be concluded that these high level conifers should be inter-cultivated with Populus ciliata for successful establishment of field plantations during their early stages of growth and development.
