Abstract
Comparative performance of five wheat varieties, viz., WH-147, S-308, WH-896, WH-542 and WH-533 grown under 5 m x 5 m and 10 m x 10 m spacings of Dalbergia sissoo Roxb. and two wheat varieties, viz., HD-2285 and WH-542 grown along Eucalyptus tereticornis Smith and Populus deltoides Marsh windbreaks was studies. Recently released wheat variety, WH-542 performed better under both block plantation of sissoo and the windbreak of poplar. However, with eucalypt windbreak wheat variety, HD-2285 out yielded WH-542. Grain yield, irrespective of variety, increased with an increase in distance from the windbreaks as well as with increased tree spacing in block plantation and at 10 m x 10 m spacing the grain yield of WH-542 and WH-533 was at par with control. Eucalypt tree belt had more adverse effect on wheat than the poplar tree belt.
