An experiment was conducted to study the effect of modified microclimatic conditions on wheat intercropped with Eucalyptus tereticornis and Dalbergia sissoo. There were fifteen tree rows of each, Eucalyptus tereticornis and Dalbergia sissoo (planted in a Neider fan design, in March, 1989) at the angle of 24° from each other starting from north in anticlockwise direction. Both the experiments have separated control (i.e. sole crop) treatments. Whea cv. PBW-226 was intercropped with both the tree species during rabi season 1996–97. Treatments 1 (0°-24°), 2 (120°-144°) and 3 (216°-240°) were compared with control. Grain yield ranged from 61.10% to 51.23% below eucalyptus canopies and from 80.57% to 71.58% below shisham canopies of control. Biological yield below eucalyptus and shisham ranged from 61.63% to 56.02% and from 72.02% to 69.16%, respectively. Higher harvest index was found in some of the treatments below eucalyptus and in all the treatments below shisham canopies, than that of control.
