Popis: ments toward minimum and zero tillage systems in many parts of the Canadian prairies and northern U.S. Great The opportunity to include late-season cover crops in northern Plains and significant reduction in the practice of sumcropping systems has been enhanced with the adoption of winter cereal production; however, cover crop feasibility has not been evaluated mer fallow. There is also increasing interest in alternain these regions. Field experiments were conducted at two sites in tive forms of nutrient management, particularly the role Manitoba in 1998 and 1999 to (i) assess establishment and dry matter of legumes in supplying N to nonleguminous crops (DM) production of legume cover crops that were relay-cropped through rotation and intercropping. [alfalfa (Medicago sativa L.) and red clover (Trifolium pratense L.)] The role of forage legume crops in improving agriculor double-cropped [chickling vetch (Lathyrus sativus L.) and black tural sustainability is well recognized. Benefits include lentil (Lens culinaris Medik. subsp. culinaris )] with winter cereals higher grain protein levels, higher yields, weed suppres[winter wheat (Triticum aestivum L.) and fall rye (Secale cereale L.)], sion, increased soil N, and improved soil properties (ii) assess the effect of relay cover crops on cereal grain yield, and
