  1. Developing Perennial Grains Lee DeHaan The Land Institute

  2. No-till cropland Central Iowa J. Scheibel 2013 2.8 cm of soil loss reduces productivity by about 7%, due primarily to loss of water infiltration, water holding capacity and nutrient supply Pimental et al. 2004

  3. Just developing new software will never make a laptop

  4. 20% Kernza

  5. Field Performance of Starting and Selected Kernza Plants Forage Varieties

  6. 168 florets 105 florets 50 florets

  7. Kernza plots in Michigan nearly eliminate leaching of nitrates into the ground water. Organic fertilizer system has less leaching, but the annual wheat still “leaks” much more than the perennial Kernza. Nitrate concentration in water below the root zone (mg/L) Culman et al. 2013

  8. B1126F3

  9. Ray florets per head: • 2006 average= 30, max = 42 • 2008 cross >45; 2010 cross if > 60; • 2012 average = 52, max = 164

  10. Silphium integrifolium Helianthus maxamiliani

  11. Sorghum halepense Sorghum bicolor

  12. PerennialRice • Soil erosion in uplands of southeast Asia has been a serious problem that led to the project of developing perennial upland rice at IRRI (IRRI 1989) Upland Rice in Yunnan, China

  13. Also could aid aerobic rice production

  14. Yields of PR 23 perennial (ratooning) rice over 3 harvests (2 years)
