Technical Abstract: Improved soil and water conservation practices have resulted in more intensive and diverse cropping systems in the Northern Great Plains. Developing crop sequences for diverse cropping systems to take advantage of synergism among crops can be a problem. No-till field research was conducted 11 km southwest of Mandan ND on a Wilton-Temvik silt loam (fine-silty, mixed, superactive, frigid Pachic and Typic Hapulustolls) to determine the influences of previous crops and crop residues on seed and residue production of buckwheat (Fagopyrum esculentum), canola (Brassica napus), chickpea (Cicer arietinum), corn (Zea mays L.), dry pea (Pisum sativum L.), grain sorghum (Sorghum bicolor L.), lentil (Lens culinaris), proso millet (Panicum miliaceum L.), sunflower (Helianthus annus L.), and spring wheat (Triticum aestivum L.) in 2003 and 2004. Crop sequence enhanced seed production for corn, dry pea, grain sorghum, proso millet, and sunflower, when compared to the crop seeded on its residue. For these crops, seed production was enhanced by up to three-fold. Seed production of chickpea and wheat were not influenced by crop sequence. Residue production was less responsive to crop sequence and in most cases was not different than the crop seeded on its own residue.
