8578. Pannkuk, Chris. n.d.. Estimating N credits for no-till wheat.. unpublished report, Land Management unit, USDA-ARS, Pullman, WA 99164.
N contributions from tinga pea (hayed or green manure) and black medic (green manure) of 70, 54, and 59 lb N/ac, respectively, were made on a subsequent spring wheat crop. All crops were planted no-till. Poor wheat stand establishment after the green manure tinga pea may have caused the low apparent contribution. Three nitrogen rates of 0, 50, and 100 lb N/ac were used. Wheat yields after legume at zero N were about twice as high as in continuous wheat, but the 100 N rate brought the latter yields up to par with the wheat after legume.
