摘要: A study was conducted around Chandigarh (Punjab), India to assess the effect of Populus deltoides shelterbelt on wheat. Crop density, root and shoot length, biomass grain yield wheat at crop maturity were significantly lower, up 12 ± 1 m in fields sheltered by P. than unsheltered plots. The reduction comparatively more that other parameters. observed growth could be attributed phytotoxic interference phenolics from tree with crop.
