Double rows of tall wheatgrass (Agropyron elongatum) were planted as barriers 48 ft apart near Culbertson, MT. The greatest soil water gain occurred during the harvest to spring period, with a precipitation storage efficiency ranging from 41-57 %. Annually cropped wheat and spring wheat following fallow responded positively to barrier protection. Yields were highest in the annual crop rotation of wheat-barley-safflower, followed by the 3-yr rotation with fallow. The traditional fallow-crop system had the lowest yields. Net returns paralleled yield results, and in most instances there was an economic benefit from the barriers. Also, safflower had a high net return and appears to have potential as an alternative crop in Montana.
