SLIDE CONTENTS
  1. Row Patterns - Tillage John Baldwin Univ. of Georgia
  2. Topics Rotations Land Prep and Fertilization Varieties Seed Disease and Nematodes Insects Cultural Practices Weed Management
  3. TSWV Varieties Planting Date Seeding Rate Row patterns Tillage In-furrow insecticide
  4. Yield Losses 20-40 lbs/A ($4-10/A) for each percent of row feet affected 50% affected = 1000-2000 lb/A yield loss Early season infection worse than late Levels seen in 95-97 were a real threat to survival of the peanut industry in GA
  5. Why does severity vary from field to field? Severity affected by cultivar, planting date, plant population, at-plant insecticide, row pattern, tillage, (adjacent crops?, others?) Impact of each of these is not equal, but additive Use of multiple practices can greatly reduce severity and increase yield
  6. Twin Vs. Single Rows Less TSWV Better Yield and Grade Quicker Canopy Closure
  7. Seed Management Twin and Single Rows Seeding Rates Seed Quality
  8. Seeding Rate/Acre for Various Peanut Varieties 6 seed/ft single 3 seed/ft twin
  9. The Formula is: Seed/ft x row length seed count per pound
  10. Ga Green Seeding Rate Tests 6 Locations-1999 & 2000
  11. Effect of Seeding Rate on Yield and Grade of C99-R peanut planted in Twin Row patterns at Four locations during 1999-2001
  12. In-Furrow insecticides on Twin Rows Thimet 3.5 on each twin row Temik 4 on each twin row Ortene 4 oz/ 100 lb of seed .
  13. Reduced Tillage Strip Tillage Less LCBs Less TSWV Twin Vs. Single Rows Water Conservation
  14. Advantages for Reduced Tillage Reduces Labor Reduces Time Reduces Fuel Less Machinery wear Traps Soil Moisture Improves water availability
  15. Challenges for Peanuts One versus Two Pass System Activation of Herbicides Plant Stands Cover Crop and Level Fields Heavy Soils Harvest Losses More Detail to Management
  16. Strip till into Rye
  17. Strip Till rye mulch Contil farm
  18. Twin Row Strip Till 2001
  19. Can you get to much mulch?
  20. Yield of 3 Peanut Cultivars planted in Single and Twin Row Patterns from 1999-2001 Georgia Green (13 locations) AgraTech 201 (7 locations) Georgia Hi/Ol (4 locations)
  21. Effect of Row Pattern on Yield, Grade and TSWV incidence of 11 peanut cultivars at 13 locations for 1999-2001
  22. Effect of Row Pattern on Yield, Grade and TSWV incidence of 11 peanut cultivars at 13 locations for 1999-2001
  23. Yield and Grade of Six peanut cultivars planted by strip till and conventional methods on twin or single rows at 13 locations 99-2001
  24. Effect of Row Pattern on Yield, Grade and TSWV incidence of 11 peanut cultivars at 13 locations for 1999-2001
  25. Terms to Remember No till saves you time and labor but you better be on time with your labor If it donít rain it donít matter Good judgment comes from experience and experience comes from poor judgment
