A field experiment was conducted during the winter seasons of 1994-95 and 1995-96 to find out the response of five wheat (Triticum aestivum L.) varieties to two spacings of Dalbergia sissoo Roxb. in an agrisilviculture system. Both the tree canopies of 5x5 m spacing and 10x10 m spacings of D. sissoo had adverse effect on plant dry matter production, leaf area index, earheads/m and grains/earhead of intercropped wheat, resulting in 71 per cent decrease in wheat yield under 5x5 m spacing and 24 per cent under 10x10 m spacing as compared to control (without trees) field. Among the wheat varieties, WH 533 and WH 542 showed greater tolerance to shade and their yield did not differ significantly from control when intercropped with 10x10 m spacing of D. sissoo.
